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.
