HTML
The markup language that defines the structure of every web page.
Build the screens, forms and interactions of websites in HTML, CSS and JavaScript.
UI developers turn design mockups into working web pages: they write the HTML, CSS and JavaScript for layouts, buttons, forms and animations, and make them accessible and fast on every screen size. They use frameworks such as React, Git, browser developer tools and design handoff files from Figma. Entry is often a portfolio of live sites or a certificate; a degree is not required.
Take these courses in order, from beginner to mid-level.
The shared base every STEM career uses: working with numbers and units, testing ideas fairly, handling data and code, and explaining your work.
The everyday computer, internet, safety and AI skills every tech and STEM job assumes you already have.
Learn how the web works and build, style and publish your own responsive website with semantic HTML and modern CSS.
The programming language of the web: variables, functions, the DOM, arrays and objects, and fetching data from APIs.
Write clear emails and documents, present and run meetings, work well on teams, and navigate résumés, interviews and networking.
The practical math behind tech and STEM work: numbers, algebra, functions, geometry, logic and counting, with short code exercises.
Use the terminal with confidence, track your work with Git, and collaborate on GitHub with pull requests.
Learn hierarchy, layout, type, colour and icons, then build and critique real screens in Figma.
