So you want to learn to use CSS?
If you want to be a successful web designer, a solid grasp of CSS is a must. Even if you don't do the coding yourself, understanding how it works will help you design for the web. We've built a comprehensive guide to help you learn CSS online, whether you're just getting started with the basics or you want to explore more advanced CSS. This Learning Guide will help you:
- Learn CSS from scratch.
- Build on your CSS experience to write better code faster.
- Explore the most recent developments in CSS.
We'll start with a basic explanation of what CSS is and how it works. Then we'll get into the fundamentals of CSS, such as typography, layout, colors, and backgrounds. After that, we'll explore some more complex areas of CSS and take a peek at what the future of CSS may hold. And we'll finish by looking at CSS preprocessors and animation.
In each section, we'll provide plenty of resources for you to use to learn more about a particular area. With this guide and the courses and tutorials we link to within it, you have all the information you need to go from CSS novice to pro.
1. What Is CSS?
CSS stands for Cascading Style Sheets, documents that contain styling rules that describe how HTML elements are displayed. CSS allows you to control the layout of multiple web pages all at once.
How Does It Work?
CSS works hand in hand with HTML; HTML sorts out the page structure, while CSS adds style, makes it look pretty, and allows you to introduce subtle levels of interaction.
Multiple style rules can point to one HTML element, in which case there needs to be a way to determine which rule should take effect. The term cascading describes the process of filtering down from general rules, until the most specific rule is encountered. That rule is then chosen to do its work.
CSS is read by web browsers. They take the HTML markup document, and then they apply the CSS styling rules to the elements within that document.
Learn HTML Basics
This guide assumes that you already have a basic understanding of HTML. If you don't, you can get up to speed quickly in our short course on HTML basics. By the end of this short course you’ll know what HTML is, how it works, and how to use its most common elements.
2. The Fundamentals of CSS
Typography, Layout, Colors, and Backgrounds
It's time to master the fundamentals of CSS: typography, layout, colors, and backgrounds.
In Start Here: Learn CSS Typography, you'll start by learning how CSS affects the way a website displays, what CSS selectors are, what CSS properties are, and the coding syntax you’ll need to know to write your own CSS.
In our Start Here series of courses, Kezz Bracey will go on to show you how to build the typographic foundation of your site, how to create the most common types of layouts in web design, and how to breathe some life into the site you’ve been creating using CSS colors and backgrounds.
Once you've got to grips with the basics of backgrounds, check out this tutorial for an in-depth look at the upgraded background property and the new capabilities beyond just adding a CSS background image or color.
CSS positioning is arguably the most fundamental skill in web design; it powers layouts and hence forms the foundation of everything inside those layouts. That said, it can be quite tricky to wrap your head around when you are first starting out.
By the time you’ve finished this course, you’ll have a firm grasp of the essential principles you need to drive your layouts. You’ll learn each of the four types of positioning used in CSS, as well as how to work around some of the oddities that can pop up when using them.

Learn in Community
Why not find your own heroes on a social coding site like GitHub or CodePen? The best thing about networks like these is the advice everybody gives each other; if you have a CSS problem, someone will have had it before you and will be willing to lend a hand. Remember, you can always ask for help in our forum!
Get to Grips With Browser Support
Browsers don't always interpret style rules the same as each other, and as browsers develop, so too does their support of newer styling proposals. It's important to understand how the major desktop and mobile browsers will treat your CSS.
It's often the browser manufacturers themselves who experiment with CSS properties, in the hope that their suggestions will be adopted by users. Ultimately, it's down to the World Wide Web Consortium (W3C) whether CSS properties are standardized or not.
Fortunately, all modern browsers (such as Google Chrome, Mozilla Firefox, Apple Safari, Opera, and Microsoft Edge) have proactive updating management, which should stop older versions floating around for too long.
However, there are differences between each of these browsers, irrespective of how up-to-date they happen to be. Some CSS will be well supported in one browser but interpreted differently in another, so for this reason it's sound advice to pay attention to browsers.
Here are some useful resources which will help you on your way:
- BrowserStack is quite simply the best cross-browser testing tool available today. Use it to see how different browsers and platforms mess with your CSS.
- Can I Use... is an invaluable website for checking which CSS properties are supported in which browsers.
3. Next-Level CSS
Once you've mastered the fundamentals, there's still lots to learn to really make the most out of everything CSS has to offer, from frameworks that help you organise your CSS to CSS libraries and creating flexible grid-based layouts using the box model.
SMACSS (Scalable and Modular Architecture for CSS) is a set of CSS guidelines which organizes your CSS rules into reusable modules. In this course, Adi Purdila will introduce you to this great front-end framework!
Essential CSS Libraries
In this next course, you’ll learn how to use ten essential CSS libraries for web designers. You’ll learn about resets, animations, transitions, and typography related libraries. You’ll be using Bower to manage your projects, to make sure that everything stays up to date and is easily maintainable.
The CSS Box Model
Understanding the CSS box model is crucial for getting your designs to behave as you want them to. In these two courses, you'll learn you how to master the box model, take control of your layouts, and use Flexbox to create flexible and grid-based layouts without having to rely on floats or inline-block elements.
Now it's time to build on what you've learned by trying some practical projects! These three courses use CodePen so you can easily follow along.
Take some time to explore the incredible results you can achieve using next-level CSS. These CSS tutorials are perfect for expanding your knowledge and digging further into grids, blending modes, counters, and units.

The Future of CSS
CSS is constantly evolving, and you can remain current and ahead of the field by knowing what the future is likely to look like. In these courses and tutorials, you'll learn about some of the bleeding-edge features of CSS, such as CSS selectors, layout modules, filters, pseudo-elements, and adding drop caps so you can take your designs to the next level.
4. CSS Preprocessors
What Is a CSS Preprocessor?
A CSS preprocessor is a scripting language that extends CSS and allows you to do a number of things and can dramatically improve your workflow. Preprocessors help you to write well organised code that's easier to maintain and allow you to use code shared by other people, but the biggest advantage is that they save you time.
This is a quick-fire explanation of CSS Preprocessors, in 60 seconds!
Learn Sass, LESS, and Stylus
Sass, LESS, and Stylus are the three most mature and stable CSS extension languages around. We have courses that will get you up to speed with all three!

5. CSS Animation
Get Started With Web Animation
Motion has become a really important part of the web design field in recent years. Motion and animation add layers of dimension to an interface, aiding the user, offering feedback, delighting, and engaging along the way.
CSS animation techniques are often a web designer’s gateway into the world of motion, and the best way to get started is to check out our post.
Alternatively, you can jump right in with our animation course and learn practical ways to create animations for buttons, pricing tables, and other web elements, using concise CSS and jQuery.
