Career role

Front-End Developer

Front-end developers build everything users see and interact with in the browser: layouts, forms, navigation and interactive features. They turn designs into accessible, responsive and fast interfaces using HTML, CSS, JavaScript and usually TypeScript with a component framework.

What the job involves

  • Turn designs into responsive pages that work on every screen size.
  • Build interactive components such as forms, menus, dialogs and data tables.
  • Fetch data from APIs and show loading, empty and error states.
  • Keep interfaces accessible, fast and consistent across browsers.

Core skills

  • Semantic HTML and accessibility
  • CSS layout (Flexbox, Grid) and responsive design
  • JavaScript and the DOM
  • TypeScript
  • A component framework (such as React)
  • Browser developer tools

Your learning path

Work through the steps in order. Each one links to the lessons and practice to use.

  1. Step 1: Semantic, accessible HTML

    Every interface starts with well-structured HTML. Use the right elements for headings, navigation, buttons and forms so the page works for keyboards and screen readers too.

  2. Step 2: CSS layout and responsive design

    Master the box model, Flexbox and Grid, then make layouts adapt with media queries and container queries.

  3. Step 3: Polished, maintainable styling

    Custom properties, transitions, animations and dark mode make interfaces feel finished. A clear CSS architecture keeps large style sheets manageable.

  4. Step 4: JavaScript, the DOM and events

    Learn the language properly, then use it to update the page, respond to events and store small amounts of data in the browser.

  5. Step 5: Asynchronous code and APIs

    Interfaces load data from servers. Learn promises, async and await, fetch, and JSON.

  6. Step 6: TypeScript and components

    TypeScript catches mistakes before the code runs, and component frameworks keep big interfaces organized. Learn TypeScript here, then pick a framework.

    • End-to-end testing with Playwright

  7. Step 7: Prepare for interviews

    Expect questions on HTML semantics, CSS layout, JavaScript behaviour (closures, this, the event loop) and small UI coding tasks.

Projects to build

Projects prove your skills and give you something to show.

  • A responsive portfolio site that scores well on accessibility checks.
  • A searchable, filterable product list that loads data from a public API.
  • A multi-step form with validation and saved progress in local storage.
