Front-end designs and creates website and app interfaces, bringing user experience to life. It's the visible part we interact with on sites and stores.
Front end programming
What does a front-end developer do?
A front-end developer builds websites and web applications, focusing on their visual elements and functionalities. They should deliver a site that is aesthetically pleasing and clear, and above all, usable. Nowadays, dynamic sites are most often designed, which allow users to interact with the site. However, for smaller business sites, you can build a static site that appears to the search engine exactly the way it is stored on the server. This type of site does not contain any elements for user interaction.
Front-end developers often have knowledge of User Experience and User Interface. This allows them to build not only an eye-pleasing layout for the site, but also to make the process of user navigation through the site as simple as possible. Therefore, their job is to build layouts for subpages and individual blocks, create intuitive and user-friendly navigation, and attract the user's attention with interesting graphics or animations.
Front end languages and technologies
A front-end developer uses several programming languages. They allow them to write instructions for the computer on how the various elements of the site should look and where they should be located. The basic front-end languages are:
- HTML (Text Markup Language), which is a character coding language that enables the structure of a website;
- CSS (Cascading Style Sheets), which is responsible for the appearance of the website, and therefore determines the colors and positions of the various elements on the page, the type and size of fonts, and even allows you to create interesting effects and animations;
- Java Script is the primary front-end language, which allows you to introduce interesting functionalities on the site and make the user interact with it.
Additionally, the front-end developer uses a number of frameworks and libraries that significantly improve work and optimize code length, examples of which include:
