<p class="summary">Cascading Stylesheets — or {{glossary("CSS")}} — is the first technology you should start learning after {{glossary("HTML")}}. While HTML is used to define the structure and semantics of your content, CSS is used to style it and lay it out. For example, you can use CSS to alter the font, color, size, and spacing of your content, split it into multiple columns, or add animations and other decorative features.</p>

<h2 id="Learning_pathway">Learning pathway</h2>

<p>You should learn the basics of HTML before attempting any CSS. We recommend that you work through our <a href="/en-US/docs/Learn/HTML/Introduction_to_HTML">Introduction to HTML</a> module first. In that module, you will learn about:</p>

<ul>
 <li>CSS, starting with the <a href="/en-US/docs/Learn/CSS/Introduction_to_CSS">Introduction to CSS</a> module</li>
 <li>More advanced <a href="/en-US/docs/Learn/HTML#Modules">HTML modules</a></li>
 <li><a href="/en-US/docs/Learn/JavaScript">JavaScript</a>, and how to use it to add dynamic functionality to web pages</li>
</ul>

<p>Once you understand the fundamentals of HTML, we recommend that you learn HTML and CSS at the same time, moving back and forth between the two topics. This is because HTML is far more interesting and much more fun to learn when you apply CSS, and you can't really learn CSS without knowing HTML.</p>

<p>Before starting this topic, you should also be familiar with using computers and using the web passively (i.e., just looking at it, consuming the content). You should have a basic work environment set up as detailed in <a href="/en-US/docs/Learn/Getting_started_with_the_web/Installing_basic_software">Installing basic software</a> and understand how to create and manage files, as detailed in <a href="/en-US/docs/Learn/Getting_started_with_the_web/Dealing_with_files">Dealing with files</a> — both of which are parts of our <a href="/en-US/docs/Learn/Getting_started_with_the_web">Getting started with the web</a> complete beginner's module.</p>

<p>It is recommended that you work through <a href="/en-US/docs/Learn/Getting_started_with_the_web">Getting started with the web</a> before proceeding with this topic. However, doing so isn't absolutely necessary as much of what is covered in the CSS basics article is also covered in our <a href="/en-US/docs/Learn/CSS/Introduction_to_CSS">Introduction to CSS</a> module, albeit in a lot more detail.</p>

<h2 id="Modules">Modules</h2>

<p>This topic contains the following modules, in a suggested order for working through them. You should definitely start with the first one.</p>

<dl>
 <dt><a href="/en-US/docs/Learn/CSS/Introduction_to_CSS">Introduction to CSS</a></dt>
 <dd>This module gets you started with the basics of how CSS works, including using selectors and properties; writing CSS rules; applying CSS to HTML; specifying length, color, and other units in CSS; controlling cascade and inheritance; understanding box model basics; and debugging CSS.</dd>
 <dt><a href="/en-US/docs/Learn/CSS/Styling_text">Styling text</a></dt>
 <dd>Here, we look at text-styling fundamentals, including setting font, boldness, and italics; line and letter spacing; and drop shadows and other text features. We round off the module by looking at applying custom fonts to your page and styling lists and links.</dd>
 <dt><a href="/en-US/docs/Learn/CSS/Styling_boxes">Styling boxes</a></dt>
 <dd>Next up, we look at styling boxes, one of the fundamental steps towards laying out a web page. In this module, we recap the box model, then look at controlling box layouts by setting padding, borders and margins, setting custom background colors, images, and fancy features such as drop shadows and filters on boxes.</dd>
 <dt><a href="/en-US/docs/Learn/CSS/CSS_layout">CSS layout</a></dt>
 <dd>At this point, we've already looked at CSS fundamentals, how to style text, and how to style and manipulate the boxes that your content sits inside. Now, it's time to look at how to place your boxes in the right place in relation to the viewport, and one another. We have covered the necessary prerequisites so we can now dive deep into CSS layout, looking at different display settings, modern layout tools like flexbox, CSS grid, and positioning, and some of the legacy techniques you might still want to know about.</dd>
 <dt>Responsive design (TBD)</dt>
 <dd>With so many different types of devices able to browse the web these days, <a href="/en-US/docs/Web/Guide/Responsive_design">responsive web design</a> (RWD) has become a core web development skill. This module will cover the basic principles and tools of RWD; explain how to apply different CSS to a document depending on device features like screen width, orientation, and resolution; and explore the technologies available for serving different videos and images depending on such features.</dd>

<h2 id="Solving_common_CSS_problems">Solving common CSS problems</h2>

<p><a href="/en-US/docs/Learn/CSS/Howto">Use CSS to solve common problems</a> provides links to sections of content explaining how to use CSS to solve very common problems when creating a web page.</p>

<p>From the beginning, you'll primarily apply colors to HTML elements and their backgrounds; change the size, shape, and position of elements; and add and define borders on elements. But there's not much you can't do once you have a solid understanding of even the basics of CSS. One of the best things about learning CSS is that once you know the fundamentals, usually you have a pretty good feel for what can and can't be done, even if you don't actually know how to do it yet!</p>
