Operating A Website
It is difficult to understand what web development is without knowing how a website works. Although technology has changed rapidly over the years, the functionality of a website as well as the basic technology has hardly changed.
For the website to work, you first need a web browser. It can parse and render HTML and CSS into content, a format we often see under the name “web page”.

What Skills Does A Web Developer Need To Have?
A web developer will need many skills, of which there are 3 main skills front-end skills, back-end skills, and design analysis skills.
1. Front-end skill
The front-end is the “front” part of the website, where it displays and interacts with users. You can become a front-end developer if you like designing and being close to people. With the front-end, you need a set of key skills:
- Basic knowledge of HTML/CSS/JavaScript.
- Knowledge of UX/UI.
- Design skills (For example, Adobe Photoshop)
- Understanding of some famous frameworks and libraries such as jQuery, AngularJS, EmberJS, etc.
- How to design a standard responsive interface.
2. Back-end skill
If the front-end is the appearance, the back-end is the interior of the website, where the users cannot see. It helps the website system to operate stably and smoothly. To become a back-end developer, you need the following skills:
- Server-side languages to write back-end like Java, Python, Ruby, C#…
- Knowledge of web frameworks that come with programming languages such as Rails, Spring, ASP.NET MVC, Django, etc.

- Basic knowledge about websites, about some CMS such as WordPress, Umbraco, Joomla, etc.
3. Design analysis skills
You can learn either the front-end or the back-end skills to become a web developer. However, most web developers today know both of those skills and are often referred to as full-stack developers, who possess the ability to analyze the website’s design.
Design analysis skill is a useful skill because you will know how a website will function inside and out, from start to finish.
