Web development terms


Are you new to web development? If so, you’re probably overwhelmed by all of the technical terms and concepts. Don’t worry, you’re not alone! To help you better understand web development, we’ve put together a beginner’s guide and glossary of web development terms.

This guide will provide definitions for the most common web development terms so you can confidently navigate the world of web development.


Web development encompasses the tasks involved in designing, building, and managing a website. This can involve anything from writing the code behind the website, to managing the content on it. Web developers may also be responsible for ensuring that the website meets accessibility standards, as well as other legal requirements.

Web development may also encompass more complex tasks such as developing applications for mobile devices or integrating data from other websites.

Web development terms 1

It is important for web developers to keep up with industry trends in order to remain competitive in the web development market. Additionally, web developers must possess strong problem solving skills in order to debug issues that may arise during the course of web development.

Web developers should also have a basic understanding of database design and architecture as these concepts are integral to successful web applications. Lastly, web developers must have good communication skills in order to work collaboratively with other members of the web development team.



HTML stands for HyperText Markup Language and is the primary language used in web development. HTML defines the structure and content of a web page, along with other elements such as images, videos, and links.

HTML is written using a set of tags, which tell the browser how to display a particular element. It serves as the foundation for all other technologies and is necessary for any web page to exist. This is one of the first web development terms people hear when they begin their web development journey.


2. CSS

CSS is another popular web development term known fully as Cascading Style Sheets and is one of the key technologies used in web development. It is a style sheet language that is used to define the appearance and feel of webpages. CSS allows you to specify how elements on a webpage should be presented, including font sizes, colors, borders, and margins.

By using CSS, developers can design pages that have a consistent look across different devices and platforms. Html can be likened to a house with no paint, and CSS could be said to be the paint, color used to beautify a house.


JavaScript is an important part of web development, as it is a scripting language that can be used to control user interactions on websites. It can be used to enhance website content by creating animated features, dynamic webpages, and interactive elements. JavaScript code can also be used to manipulate HTML documents and other web-based technologies.

It is typically used in combination with HTML and CSS, allowing for more complex programming. Popular JavaScript libraries such as jQuery, React, and Vue are often used by developers to simplify their code and create powerful website applications.


Domain name - Web development terms

A domain name is a distinctive combination of letters and digits that serves to identify a website on the Internet. A web development project typically starts with a domain name registration, which is essentially reserving your chosen website name for use.

The domain name is linked to an IP address, which serves as a unique identifier for web servers and computers connected to the Internet. When users enter the domain name in a browser, they are directed to the server hosting the website.

Domain names help to make the web more accessible to users and are a critical part of any web development project. This is one of the most important web development terms.


Https (Hypertext Transfer Protocol Secure) is a protocol that is used to secure communications between web servers and clients. It is an essential part of web development as it encrypts data sent from one computer to another and authenticates the website or service the user is accessing.

Https also helps to protect sensitive information such as passwords and credit card numbers by using secure encryption algorithms. When you are visiting a website with https, your browser will show a padlock icon to confirm that the connection is secure. To ensure users experience safe and secure browsing, it is important for website developers to always use https when designing websites.


Caching is an important aspect of web development and is used to improve website performance. It involves temporarily storing data, such as images, HTML files, and scripts, so that they can be quickly accessed without having to retrieve them from the server.

This can result in faster loading times and improved user experience, as the browser doesn’t have to wait for a response from the server every time it needs a certain file. By reducing the amount of traffic going to the server, caching can also help reduce bandwidth usage and reduce the load on the server.

7. API

API - Web development terms

Application Programming Interface is used in web development to allow different applications to interact with each other. APIs act as a gateway for allowing different services, such as websites or apps, to communicate with each other without having to manually enter information.

An example of an API might be one that allows a weather website to display data from a weather service provider. By using APIs, web development projects can become much more efficient and streamlined.


When it comes to web development, an algorithm is a set of rules that are used to solve a problem. Algorithms are an essential part of coding and programming, as they provide the structure and foundation of the code written. An algorithm can be described as a step-by-step procedure for solving a particular problem.

They are used to create website functions such as search engine optimization (SEO) and user interface (UI) design. Algorithms can also be used to create artificial intelligence (AI) systems, allowing websites to interact with users in a more intelligent way.


An application is a type of software that serves a particular purpose for web development. It’s the end product of a web development project and is typically the result of an iterative process of design, coding, testing, and deployment. Examples of applications include mobile apps, desktop apps, and web-based applications.

Applications can also be used to automate or streamline business processes, such as managing customer relationships and tracking inventory. Web developers are often responsible for developing, deploying, and maintaining applications for their clients.


This is a very important web development term. It is a collection of data that is organized and stored in such a way that it can be easily accessed, managed and updated. The database stores information in the form of records and fields which are related to one another.

In web development, databases are used to store website content such as images, videos, text and other types of data. Databases can also be used for user authentication and tracking user activity on a website. Popular database systems used in web development include MySQL, PostgreSQL, Oracle, MongoDB and Microsoft SQL Server.



A web development framework is a software library that provides an application programming interface (API) for web developers to simplify the development process. Frameworks typically include structure, files and code to speed up the development of websites and web applications.

Common frameworks used in web development include React, Angular, Laravel and Symfony. Each framework has its own pros and cons so it’s important to do research to understand which one best suits your project needs.

Popular web development frameworks are easy to use, have plenty of tutorials and online resources available, offer regular updates and are highly customizable.


Hosting is a critical component of web development. It is a web development term every developer should know. It refers to the server on which your website will be stored and accessed. Without hosting, your website would not be visible online.

There are many different types of hosting services available, from shared hosting (where multiple sites share a server) to managed hosting (where a company manages the server for you). Depending on your website’s size, needs, and budget, there is likely a type of hosting that is best for you.


This focuses on organizing, structuring, and labeling content in order to make it easier to find and use. It also helps to define the navigation structure of a website so that users can easily move around and access information.

The purpose of Information Architecture is to provide an intuitive way for users to interact with a website’s content by allowing them to find what they need quickly and easily. As such, IA is an integral part of any successful web development project.


This is a piece of software that adds specific functionality to a larger piece of software. Plug-ins can be used to extend the functionality of a website or web application in order to enhance user experience or increase functionality.

Plug-ins are developed by third-party developers and are typically free for users to install on their websites. Common examples of web development plug-ins include analytics, SEO optimization, forms, shopping carts, and more. Plug-ins are a powerful and versatile tool for web developers as they offer flexibility and expandability to their websites.



Responsive web development is a design approach which allows webpages to adapt to the size and resolution of any device. It enables developers to create layouts that fluidly respond to the user’s device, whether it’s a desktop, tablet, or mobile phone.

By using flexible grids and layouts, developers can ensure that a website looks just as great on an iPhone as it does on a laptop computer.This is made possible by using CSS media queries which allow developers to target specific resolutions and display the corresponding design. Responsive design is becoming increasingly important for web developers as more and more people access websites from mobile devices.

Responsive web development is key for providing users with the best possible experience and ensuring that content is accessible across all platforms.


Retina Ready is a term used in web design to refer to the sharpness and clarity of images, text, and other elements on a website. With Retina Ready web designs, high-resolution displays like Apple’s Retina display can display content with a much higher resolution than standard displays, resulting in a sharper, more vivid viewing experience.

To make sure your website is Retina Ready, you will need to use images with twice the amount of pixels that would normally be used for the same image size on a non-Retina display. This will ensure that your content is displayed in optimal quality on Retina Ready devices.


A server is a computer system that provides services to other computers or web clients. It stores and shares web design files, such as HTML, CSS, and JavaScript, so that when someone accesses your website, they can view the content of your website. Servers also host databases and applications.

There are different types of servers which includes web servers, application servers, database servers, and more. It is important to understand the role that each type of server plays in web design, as they all serve different purposes.


This is very important term and a key part in the web development glossary. It stands for Secure Socket Layer, and it is a type of digital certificate that helps to secure online communications between a web server and a client browser. It provides authentication for the website, meaning that users can be sure that the site is legitimate and not an impostor.

The SSL protocol also encrypts all data that passes through the connection, making it impossible for malicious third-parties to intercept it. This makes it essential for websites that are handling sensitive user data, such as payment information or health records. Obtaining an SSL certificate requires verifying the identity of the website owner, which adds an extra layer of trustworthiness to the website.


UX - Web development terms

UX (User Experience) is a web design term used to describe the overall experience of a user when using a product or service, such as a website. UX focuses on the functionality and design of the product or service from the user’s perspective. It looks at the ease of use, intuitiveness, visual design, and other aspects that affect the user’s experience.

UX is often confused with UI (User Interface), which deals with the graphical elements of a website, such as buttons and menus. However, UX covers a broader spectrum and also incorporates web design, content strategy, copywriting, and other aspects of creating a website.

When it comes to creating a successful website, UX should be a top priority to ensure users have an enjoyable experience while they’re on your website.

20. CMS

A content management system (CMS) is a type of software that enables users to develop, manage website content. This is especially helpful for web design and development professionals who need to build, maintain, and update websites quickly and easily.

By using a CMS, users can store, format, and update content in a simple and organized way, without having to manually code HTML. CMS also provide other useful features such as templates, user roles, and security settings to help users create and manage websites with ease. One of the most popular CMS is wordpress.org.


This beginner’s guide and glossary of web development terms is a useful resource for those new to the field, providing a better understanding of common concepts and helping to navigate the world of web development confidently.

Basic Html Tutorial


In this guide, we will focus on the basic html tutorial for beginners. This is one of the most important languages in the world of web development. Html is the basis of almost every website, it is what we use to organise contents, set up headings, paragraphs, images, lists, forms and much more.

NOTE: A code editor will be put at the end of this post so you can practice as you like and also see the outputs of your codes.


HTML is a short term for Hypertext Markup Language and it’s the most widely used language to structure pages. It was created by Berners -Lee in late 1991, but HTML 2.0 was the first specification for a standard HTML, and it was released in 1995. And the current version of HTML which is widely used is HTML 5. Likened to a house, we can say HTML is like a building without painting, electricity, furnitures etc.

Most people ask this question “is HTML a programming language?”. There has been lots of debates and arguments on if it is a programming language. A programming language is a language that serves a functions such as declaring variables, modifying data and more. Examples of such languages are Javascript, Python and many more.

We can simply say HTML is a structural language used to create web pages. HTML is open-source and supported by all current browsers makes it cost-free to use and guarantees that your text, graphics, and other elements are shown as you intended. If HTML didn’t exist, all web pages would simply be plain text files like the image below.

HTML helps you format documents with headings, paragraphs, lists, images, videos, audio files, and other elements. And you can also set up navigation to link from one page to another. This language is one of the most important and foremost for every website.


Writing HTML is simple, it has to do with knowing how to position the tags and elements. To begin writing, the first thing we need is a code editor (Visual Studio code, Sublime Text, Atom) ,these are some of the most popular and powerful code editors. A code editor is program designed specifically for writing and editing codes.

After downloading your choice of a code editor, the next thing to do is a create a folder on your local computer, open it up in your code editor and create an html file. To create an html file, you name it (index.html). Index.html specifies the first or rather the homepage of every website, you can also create other html files like (about.html, contact.html and much more).

After creating your html file, you first begin by declaring your version of Html (html 5) to the browser. To do that , you create a tag with the less than symbol “<” and to close the tag you use your greater than symbol “>”. Below is an image of how to declare and set up a page to begin writing your HTML code.

Html Page Format


Tags, which are typically encased in angle brackets, are used to mark the beginning of an HTML element. The tag <h1> is an example. Tags should be opened and closed to function. (<h1> </h2> ).

In HTML, some of the basic tags are ;

  • <h1> </h1>
  • <h2> </h2>
  • <h3> </h3>
  • <h4> </h4>
  • <h5> </h5>
  • <h6> </h6>

The h1 to h6 tags are used for headings. H1 is the biggest and most important heading while H6 is the smallest and least important headings.

<!DOCTYPE html>
    <title>Hello, World!</title>
      <h1>Hello World </h1>
      <h2>Hello World </h2>
      <h3>Hello World </h3>
      <h4>Hello World </h4>
      <h5>Hello World </h5>
      <h6>Hello World </h6>

This is how headings are written in this markup language.

Another popular tag which is very useful when creating Web pages is the paragraph tag. This is usually done with the p tag.

<p> Hello World, my name is Obawharhe and this is a paragraph tag </p>

Paragraph tag always start on a new line and continues. If you want every sentence in a paragraph to begin on a new line, it is advisable to use the break tag (</br> tag ).

The function of the break tag is to take things to a new line. And it is a self closing tag. As such doesn’t need a closing tag. An example below.

<p> Hello World, </br>my name is Obawharhe and this is a paragraph </p>


Html has so many tags and not every single element will be useful to you in your Web development journey. As such below, I’ll show you some very useful elements that will be needed to customize texts on your website.

1<b> – BoldThe name is self explanatory. The bold tag helps highlight text.
<b> Hello, how are you </b>
2<strong>Strong performs almost the same function as bold but when strong is used, it is used to show that the text is very important. <strong> Hello World! </strong>
3<i>This tag is used to write contents in italic formats. <i> I am here </i>
4<em>This is used to emphasize a very important content and is most times written in italics as well. The tag is used for image captions as well.
<em> Html is fun </em>
5<small>It is used to make the font size of any text or content small. Note that small cannot replace an h6 tag because an h6 tag is an heading.
<small> A small text </small>
6<u>The tag underlines any content which is enclosed within it.
<u> My underlined text </u>
7<del>Delete tag – It’s used to either remove a text or show that the content is no longer important. When used, it strikes through the content.
<del> 5000 </del>
8<sub>It is used to create subscript text. Subscripts are usually displayed with a lower baseline and smaller text. Popular examples are ” H2O “.
<p> H <sub> 2 </sub>O </p>
9<sup>The tag generates a superscript. Superscripts are characters that are placed above the normal line. A popular example is ” 1st “.
<p> 1 <sup> st </sup> </p>
10<div>This is known as a block tag. A div is similar to a container that is used to hold contents or divide sections.
11<span>This is another type of block element. Span is similar to a container that holds contents, but it only takes up as much space as the contents.

Any of these tags could be used in a paragraph or anywhere else. The div tag can be used to divide the header, footer, and other elements, whereas the span tag can be used to divide the content into smaller chunks.

This will be discussed further in another post. Below, I will leave an example of some the tags we’ve talked about being used. You can also copy the code to a code editor to see the result.

<h1> ABOUT HTML </h1>

<p> Html is a <b>fun</b> language. </br> It is <strong>very</strong> important in the <i>development</i> of most <em>Web</em> pages. It could be <small>likened</small> to a <u>foundation</u> of a <del>horse</del> house.


Links are very important as they enable you navigate from one page to another or from one website to another website.

To add a link, the anchor tag is used <a>. Now let’s make a link to Google.

<a href="https://www.google.com"> GOOGLE </a>

We can also link it to a blog post on our site by following the same process.

Adding images in html is quite simple. This is done with the <img> tag and some attributes. Images are very important in website building, it could be used as a background, for contents and much more.

Most people prefer to resize an image (height and width) using Cascading Style Sheet popularly known as CSS ,which is a styling language. However, this is also easily accomplished using HTML.

Images in any format including jpg, png, svg, and gif can be added. The alt attribute is another significant attribute when adding images.

It is essential for visually impaired visitors, as well as when images fail to load properly. You can add images with external links or images from your folder.

The <img> tag is used as shown in the example below;

<img src="image.jpg" alt="about the image" height="150" width="150">


Lists are important for so many reasons ,they are easy to read, it makes information organized and it is easy to share. In HTML, there 3 types of list.

They are unordered list, ordered list and description list.


Unordered list are usually bulleted.

An unordered list code with result
<h2> LIST OF FRUITS  </h2>
<li> Orange </li>
<li> Apple </li>
<li> Strawberry </li>


Ordered lists are also known as numbered lists.

<li> Nigeria </li>
<li> United States of America </li>
<li> New Zealand </li>


This list is used to describe or define terms or items.

<dt> HTML </dt>
<dd> : Means Hypertext Markup Language 


Tables allow people arrange data (information) in rows and columns. A table was used when we talked about “OTHER USEFUL TAGS/ELEMENTS IN HTML”.

A table consist of a table head <th>, table row <tr> and table data <td>.

When creating tables, some developers also include table header, table body and table footer but that will be left for a more advanced tutorial.

<th> NAME </th>
<th> LEVEL </th>
<th> COUNTRY </th>
<td> John </td>
<td> 200 </td>
<td> Nigeria </td>
<td> Lisa </td>
<td> 100 </td>
<td> Belgium </td>
