Front-end Development

Bringing your websites and apps to life

What is front-end development? The 'frontend' is the interface that exists between the user and the backend.

The front end web developer is the hybrid position that sits in between backend developers and visual designers.

HTML

The front end developer takes the data provided by the back end developer and wraps it with standards compliant markup, in order to display that data to the user correctly. This can either be with straight HTML, or might use some kind of templating language like Twig, Django templates, JSX etc. All produced markup should be accessible.

CSS

Once the data has been wrapped in HTML, the developer then creates one or many CSS files that create the user interface exactly as it appears in the original mockup made by the designer, while displaying all of the data to the end user. There are many factors that need to be taken into account when writing the CSS, such as different screen viewing sizes and resolutions, different types and versions of browsers, accessibility requirements, end users' connection speeds, & etc.

JavaScript

In a traditional website, JavaScript is used to create dynamic elements in the user interface, such as lightboxes/modals, tabbed navigation, form validation, etc. In an web application, JavaScript handles nearly all of the user interaction, replacing the traditional "user clicks link, browser sends request to server, server sends response to browser, browser displays response" cycle. This is usually done using a framework such as Angular or React. A common pattern is the single-page application (sometimes referred to as a SPA) where there is only one HTML page and all paths/routes are handled via HTML5 push state. Frontend JavaScript is also used for some cross-platform Mobile Application Development frameworks.
