How To Become a Front-End Developer?


Trends and Front-End development are always changing. What worked yesterday may not work today. This can make being your Front-End developer pretty challenging. But what’s most exciting about Front-End development is that you’re always learning new technologies.

So if you’re an aspiring Front-End developer or you’re learning Front-End technology, here’s what you need to know to be a Front-End developer in 2021. But, before this, you should know what a Front-End development is?

What Is A Front-End Developer?

There are generally two parts to any web application: the Front-End or client-side of the web app is everything you see and interact with within the browser as a user.

Then there’s the Back-End or server-side of the web application where the application’s data is saved, updated, manipulated, and sent back to the client-side. For example, you’re on a video website when you click on a video. The video is retrieved from a database and served by a server that’s the Back-End.
The Front-End or the user interface displays it in the browser and allows the user to interact with the video by providing buttons, video full-screen option, pause, rewind, or share with your friends.

As a web developer, you’ll likely need to know how the Front and Back-Ends of an application interact with each other. However, many companies split these top roles into two different careers: a Front-End Developer and a Back-End Developer.

Back-End Developers

Back-End developers use programming languages like Java, Python, Ruby, and PHP to build the behind the scenes functionality of a website, such as storing and retrieving user data or securely accepting and storing credit card numbers.

Front-End Developer 

A Front-End Developer is someone who builds the user interface (UI) of websites and applications by using HTML, CSS, and JavaScript. Almost every business or company uses a website or application to communicate with its customers. Every Business or company needs the skills of a Front-End developer to create a website or application using HTML, CSS, and JavaScript. 

In this article, I’ll clear all your confusions and questions about what you need to know to be a more general but still excellent Front-End developer. 

To be a Front-End developer, you’ll need to learn different technologies, but the leading technologies are HTML, CSS, and Javascript. 

1. HTML (Hypertext Markup Language) 

HTML is the foundation of every web page. Without HTML, everything on the internet would be a shapeless block of text. Using HTML, you provide information to the web browser about how your site content is structured by defining its different parts.
For example, you surround the content of your web pages with different HTML tags to tell the browser which parts are headings, sidebars, a footer, or the main area of the site. 

One of the HTML goals is to provide reasonable semantic markup that provides information about what kind of content the HTML tag contains. The Front-End Developers use HTML to define which elements on the web page are links, lists, items, buttons, paragraphs, checkboxes, and radio buttons.

CSS is used to style the pages. Search Engines use this information to understand your website pages, and semantic markup tools help accessibility like screen readers make a more friendly sense of your content. 

2. CSS (Cascading Style Sheets) 

CSS is a design language with a lot of power. CSS helps us to configure the presentation of web pages. With CSS, we define how the pages built with HTML should look and be laid out. For example, by using CSS, we tell the browser that we want our web page to display in a certain number of rows or columns or how much space should be between each element.

We’d also use CSS to configure the fonts’ colour, the font, size of a button, make it taller or wider, smaller or bigger, place it on the left, right, or the middle of the webpage, and so on.

The need to write good CSS means that we make sure the designs are responsive and are consistent across different devices. We use CSS to create responsive web pages. It means that the web pages look awesome and function well on any screen size or device. CSS seems easy at first, but it can quickly become more difficult. 

The formatting and styling of web pages are tough. It requires a lot of practice to create stunning and eye-catching designs for web pages.

3. JavaScript 

JavaScript is the first programming language that you’re likely to learn as a Front-End developer. it’s a continuously evolving language that’s used nearly everywhere these days on the Front-End, Back-End, on mobile, and even desktop devices. 

Like the other technologies, it can be tough to code but fun to learn. Generally, Front-End developers use the Document Object Model (DOM) to write JavaScript code for the browser.

The Document Object Model is like a representation of your webpage or application that allows JavaScript and the browser to communicate with each other. HTML elements on your web page are represented by using Dom and to manipulate those elements, you can use JavaScript.
You have some text on your web page that reads Download, you’d use HTML tags to define that text as a button. With CSS, you’d control the styling of the button. 

Finally, with JavaScript, you’d write code that triggers the page or application to do something every time the button is clicked, like playing a video or submit a comment to a social media post. 

If you’re serious about being a Front-End developer, javascript is a language that you’ll have to be an expert at. 

Code Editors

The text editor is where the developers spend most of their time. It’s the code editors where you write code for any given website or application. Visual Studio Code, Atom, and Sublime Text are the most popular text editors in 2021. 

If you don’t have any idea which text editor to use as a beginner, I’ve already written about the top free text editors for developers, and you can check that out here.


These are some of the main tools and technologies you’ll use daily as a Front-End developer. You don’t need to feel like you need to learn everything at once. There are tons of resources like podcasts, videos, tutorials, books, apps, conferences, meetups, etc., on how to be a Front-End developer.

While it’s a challenge to filter out what’s most valuable as most of these resources are going to be talking about something you won’t understand. Just immerse yourself in the language and take it all in concentrate by getting comfortable with the basics HTML, CSS, and JavaScript, and the rest will come in time.
