The best and updated guide to front end development in 2021

How to be a frontend developer

You must have stumbled on the word “Web development” while scrolling through your social media accounts or surfing on the internet. Have you ever wondered why a website looks a certain way and how it is made to look that way? Or “I wish I could pull off something like that?”. Web designing determines the way a website looks while front end development is how it gets implemented on the web.

Everything that you see on the website is built with the help of front-end development (also known as front-end web development) and the people making it happen are known as Front end developers.

“A front end web developer is a software engineer who implements web designs through coding languages like HTML, CSS, and JavaScript”. If you visit any website, you can see the work of a front-end developer in the navigation, layout, and how the site looks different on your phone. For instance, the InvoZone website where you’re reading this article right now.

Why do you need to choose/specify?

The need to specify what you want to learn in website development is important to have a clear idea of your future. The problem with website development today is the excess of information that creates ambiguity and confusion in the minds of newcomers. The amount of information available on the internet can overwhelm and put you under pressure before even starting out. You shouldn’t indulge in irrelevant information as to what will be in demand three years from now and what you should learn keeping that in mind. This will not lead you anywhere, specify what you want to learn and start learning. The key here is: “YOU DON’T NEED TO LEARN EVERYTHING”.

HTML (Hyper Text Markup language) and CSS (Cascading Style Sheets) serve as the most basic building blocks of web coding. Without these two fundamental skills, you can’t create a web design. If you intend to become a web developer, you should learn HTML and CSS. This will not take more than a few weeks to get a basic understanding of either of these and you will have a workable grasp on both of these.

Learning JavaScript alongside HTML and CSS will let you add various functionality to websites. At the most basic level, JavaScript can be used to create and control maps that update in real-time, interactive films, and online games.
