What is web design?

Web design is the process of designing websites and making them attractive and functional. This web design process involves the use of all design techniques known to improve the overall appearance of a website, as well as its functional elements.

This means web designers are responsible for a multitude of tasks including graphic design, layout, user interface, responsive design, and using interactive elements to create dynamic content. Together, all of these parts will result in a positive user experience.

Web designers who can code and know how to make something visually appealing are in high demand, as they can create and maintain a responsive web design themselves. Even a basic knowledge of how to build source code will be of great help if you are a web designer. Combining your knowledge of coding with web design terminology will help your colleagues better understand your work.

5 common web design terms

Here are five of the terms of web design most common ones you should be aware of if you work as a web designer, graphic designer, or any related technology role.

Error 404

The 404 Not Found error is one of the most common errors encountered in a browser window. It means that the page you are looking for is not found on the server. It usually happens when the requested content has been removed, or if an incorrect URL has been typed. Links that lead to a 404 page error are called dead or broken links.

Why Web Designers Should Be Aware of 404 Errors
One in five website requests leads to a 404 error. This makes it one of the most common terms you'll hear as a web designer. You need to be aware of this error in order to fix the problem and get the website working properly again.


CSS stands for Cascading Style Sheets. CSS is a computer language responsible for the appearance of your web pages. CSS files dictate the colors, fonts, and layouts of websites. It is also used to add interactive features to websites, such as animations. Three CSS styles are available: internal, external, and inline.

Why Web Designers Should Know CSS
CSS is one of the most important building blocks of a site. Without CSS properties, all websites would be text based, plain and boring. CSS allows the use of colors, fonts, and interactive layouts. It also creates a responsive design, which helps a website work on any screen size or device.

Domain name

A domain name refers to the exact location of a website within a search engine. It usually goes after an "@" in an email address or after "www" in a web address. Examples of domain names are or

Why Web Designers Should Know About Domain Names
Domain names are one of the most important aspects of building a website. Without a domain name, a web page will have no address and therefore cannot be found. A web designer must understand what a domain name is and how it works.


HTML stands for Hypertext Markup Language. HTML is the most basic element of any web page. It is used to display documents and is responsible for the overall structure of a website. It is used in conjunction with other languages, such as CSS and Java, to create visual design elements.

Why web designers need to know about HTML
Every website uses HTML. A web designer must know what HTML is and how to use it. It is the most basic element of a website and acts as its foundation and structure. Therefore, without HTML, there would be no websites.


JavaScript is a programming language that allows you to implement complex functions on your site. JavaScript is used when you need to add an interactive design element to your websites, such as an animation, an interactive map, an audio or video file, or a zoom button.

Why web designers need to know about JavaScript
JavaScript is important because it controls all activities within its framework. It also manipulates the website according to user requests, so without JavaScript, your site won't work properly.

5 advanced web design terms

Learning advanced web design terminology will help you become a better web designer. Now that you know some of the key web design terms, it's time to look at some advanced terms. Although these terms are less common, they are still important to understand. If you're working in a high-level web design role, you'll find this section particularly useful.

Caching or Caching

Caching is the process of saving files to a temporary store so they can be easily accessed later. For example, this allows a browser to access files from the cache instead of from the original server, thus saving time.

Why web designers should be aware of caching
Caching helps your site load faster. Increase the speed of your network without having to sacrifice anything else. It also decreases the load on your server, which leads to faster load times and increases the user experience.

CMS or Content Management System

A content management system (CMS) is a software application that allows users to create, modify and manage the contents of a website. A CMS allows you to build a website without having to code.

Why Web Designers Should Know About Content Management Systems
It's important to know how to use a CMS if you don't know how to code. Learning how to modify, manage and create content for a site without coding is a huge advantage. It also helps save time, so even an advanced web designer who knows how to code can use CMS to build a site quickly.

DNS or Domain Name System

DNS stands for Domain Name System. DNS converts domain names to Internet Protocol (IP) addresses. Every device connected to the Internet has an IP address, and these are used for the devices to communicate with each other. The DNS server is like a phone book for the Internet.

Why web designers need to know DNS
A user doesn't know the different IP addresses of the sites they visit every day. That's why they use domain names. A web designer must know the DNS to make websites useful and easy to search.
