Web Development

Technology is a big part of today's world. People spend a lot of their time using a variety of websites and apps, from the most simple ones to ones that are quite complicated. All of those websites and apps are created by web developers and the demand for more web developers is pretty high. If you're thinking of becoming a web developer, you should be aware of the skills that are essential in order to be successful in this profession. In today's post, we will go through the most important skills a web developer needs.

1. HTML/CSS skills

HTML, or Hyper Text Markup Language, is a programming language that is used to describe the structure of information on a web page and CSS, or Cascading Style Sheets is a style sheet language that is used to style documents written in markup languages. HTML is the most used markup language across the web and together with CSS they make up the essential building blocks of a website. HTML provides the structure of the website, while CSS controls the appearance of the page, it is used to style the website. HTML elements are used to specify what kind of information is contained on a web page, for example headings, paragraphs, images, videos and other types of data. Meanwhile, CSS is responsible of the choice of fonts, colors and general layout of the website. Every website you open in your browser from social media platforms to online stores uses HTML and CSS, so if you wish to become a web developer, having a good grasp of how these languages work is very important.

2. JavaScript skills

Along with HTML and CSS, if you wish to work as a web developer, you will need a good understanding of JavaScript as well. JavaScript is a high level programming language that helps you implement complex features in a website. These features can be search bars, moving elements, interactive maps, videos or animated 2D/3D graphics. While HTML provides the structure and CSS provides the page's appearance, JavaScript provides the functionality of a website. Essentially, it makes the website interactive and brings it to life. Since its creation in 1995 it has been pretty much present everywhere on the web and is used by around 95% of the websites on the world wide web so it is highly relevant and every web developer should be able to understand it and apply it in practice.

3. Testing/debugging skills

Bugs are an inherent part of the development process. As a web developer, you should be able to test your website for any errors that might arise. In addition to this, you should know how to debug them. Testing makes sure that your code is doing what it's supposed to be doing and there are a couple of different testing methods that web developers use. There's functional testing, which looks at a particular functionality on your website and makes sure it works properly and there's unit testing, which tests the smallest bit of code that is responsible for one thing. Its purpose is to validate that each unit of the software code performs as expected. Testing plays a big role in the front end development process, so the ability to test and debug is one of the essential skills for web developers.

4. Responsive design skills

As a web developer, it's very important to understand how responsive design works. Responsive web design essentially makes sure that all of the content and pages are flexible across different resolutions and screens. Whether you're viewing a website on your smartphone or a laptop, it will be easy to navigate despite the different screen size. If the website isn't responsive, it won't be compatible either with the desktop version or the mobile version. In this day and age where a lot of people use both smartphones and computers, building responsive websites is a must. Because of this, every developer should focus on learning how to design responsive websites which in turn will impact the number of visitors that a website gets since most people like using websites that adapt to any device.

5. Interpersonal skills

As a web developer, you will be working with clients a lot of the time, which requires good interpersonal skills. You have to be a good listener, to understand the needs of the client well and to be able to collaborate with your client. Alongside this, you need to have a good work ethic and to be able to effectively manage complex situations. If you manage to attain these skills, you will be better in your work and it will be a pleasure for clients to work with you which in turn will increase the number of people who require your services.


The path to becoming a web developer might seem long and difficult, but if you pay attention to these skills and strive to develop them as well as you can, the process will become easier and smoother. After all, all great web developers have started from zero and it takes time and effort to become good but if you are dedicated and have the will to improve, nothing will seem impossible.
