Frontend Development Basic Guide

A frontend developer is a person who is in charge of the visual and interactive aspects of a website, for everything you see when you enter a particular page.

Sounds pretty clear, doesn’t it?

Although you may think that a designer is in charge of the look of your favorite site, you are only partially right. The designer is the one who creates the visual identity of the page, while the frontend developer is the one who “revives” the design and creates a functional site, using some of the programming languages ​​(HTML, JSS, CSS, etc.).

Today, one frontend developer, in addition to knowing programming languages, has knowledge of User Interface (UI) design. In addition, it is necessary to add new programming languages ​​to the repertoire.

So it’s a two-in-one approach.

The ultimate goal of a frontend developer is to make life easier for the end user – you.

That is why the original design and the idea of ​​the visual identity of a certain page are subject to change. The layout of images, links, buttons and texts on the site is adapted to the needs of visitors. And the frontend developer is the ultimate responsible person for all this to happen and not to leave the page as soon as you open it.

Who can work as front-end developer?


In terror, anyone who wants to.

In practice, preference is given to people who are willing to work in teams and communicate with other “sectors” such as designers, backend developers and project managers.

Since he is in constant communication with other team members, the frontend developer should have good communication skills.

In addition, creativity and the desire for constant learning and research is a feature of a good frontend developer who keeps pace with trends in site design and appearance.

By adapting the design to different functions on the site, there are problems for which a solution needs to be found. Quick and creative reaction and problem solving is important for anyone who would like to do this job.

As employees in the IT sector, working under pressure is not excluded due to frequent changes and breaking deadlines.

Although soft skills are essential for success and coping in the business you do, it is important to keep in mind that you cannot be a frontend developer without technical knowledge and experience, as well as knowledge of a programming language.

What technical experience do you need?

  1. HTML / CSS
    Hyper Text Markup Language is the standard language for creating a web page. It is one of the easiest languages ​​for site styling, which does not support logical operations.

HTML is used to create the structural skeleton of web pages, while CSS (Cascading Style Sheet) is used to change colors, fonts and styles.

Both HTML and CSS are essential for the frontend developer profession.

  1. JavaScript
    Interactive elements on the website, such as audio and video effects, animation are added to the site via Java Script.

Unlike HTML, CSS also supports logical operations, so with well-written code, JS can repeat some operations and tasks.

  1. Framework
    CSS and Java Script framework collect CSS and JS data that perform different tasks with the same functionality.

You do not start coding with a blank page, but the framework stores certain JS data that is already on the page.

In addition to the advantages and disadvantages of the framework, you should choose the one that suits the website you are working on.

  1. Responsive Design
    Sites should be adapted to different devices and different screen dimensions that we use daily – phone, tablet, laptop.

Sometimes the pages have data entered in their basic settings, while in most cases the frontend developer needs to recognize and “fix” the problem.

Responsive site is obtained by entering the appropriate CSS code.

  1. Testing / Debugging
    Testing is a key part of the development process of any project.

The frontend developer should have the ability to test and troubleshoot code.
