To save you the trouble of opening 36 tabs and immediately giving up, we’ve rounded up some of the best free resources for seven of the most important skills to brush up on below… HTML What is HTML? Hyper Text Markup Language (HTML) is – to put it simply – the language in which websites are built. It is used to create web pages, tell a browser how to display certain blocks of the page, and labels elements of content, among a host of other crucial functions. HTML is a basic but essential building block in the web development process, so having a good grasp on it is crucial. It’s also a great introduction in ‘thinking like a coder’, so if you are new to the world of developers, HTML is a good place to start.

We recommend heading to , an expansive but easy to digest hub of HTML tutorials, references and cheat sheets designed with both beginners and experts in mind. HTML.com CSS What is CSS? If HTML is the structure, Cascading Style Sheets (CSS) is the style. CSS goes hand in hand with HTML when it comes to making web pages readable, as it’s used to apply styles to HTML elements. These can include colors, spacing, and other decorative elements. Getting to grips with CSS is an important next step once you’ve got HTML under your belt, as it gives you much more control over how a web page is displayed; the difference between a HTML-only page and one with CSS applied is night and day.

CSS-TRICKS JavaScript What is JavaScript? The third installment in this web design trilogy is JavaScript, a programming language that enables much more complex behaviors in web pages. Used to build elements from animation and interactive elements through to the loading of new content without reloading the page, JavaScript elevates a static page (made up of HTML elements styled by CSS) into a dynamic and intuitive user experience. A mastery of JavaScript also opens up the world of browser based and third-party APIs, ready-made blocks of JavaScript code that can add exciting (and otherwise extremely difficult to build) new features to your pages. Free JavaScript learning resource: With a staggering 1300 pages of guides, techniques and articles, is a treasure trove of advice being constantly updated. Whether you’re new to JavaScript or an expert looking to brush up and learn some new tricks, this free resource should be bookmarked ASAP. The Modern JavaScript Tutorial React What is React? Developed by Facebook, React is a JavaScript based user interface development library. One of the most popular front-end development tools out there, React uses a component based framework that makes it much easier to deliver a dynamic and complex web page or app, whilst requiring less complicated coding with reusable components. A good understanding of React is especially important for front-end developers. Free React learning resource: With 67 totally free lessons, offers a hands-on chance to learn React from scratch.

It enables a team to track changes and save copies of version history, with a branching workflow that allows developers and DevOps engineers to work simultaneously on different branches, eventually merging changes into a main branch. Cloud based repositories like GitHub offer an alternative to hosting Git locally. Many, GitHub being the most widely used, have grown beyond their roots as basic repositories to become end-to-end development platforms. With the prevalence of Git and GitHub in professional programming and developer environments, getting a handle on the process can be essential.
