If you’re new to web development, be sure to read our CSS basics article to learn what CSS is and how to use it. Here we will show one HTML page displayed with 4 different stylesheets.

CSS (Cascading Style Sheets) allows you to create great-looking web pages, but how does it work under the hood? This article explains what CSS is with a simple syntax example and also covers some key terms about the language. CSS declaration always ends with a semicolon, and declaration blocks are surrounded by curly braces.

If your website has a lot of styling information included in the HTML code, it can be difficult to read and edit. By keeping the styling information in a separate CSS file, it will be much easier to read and edit your HTML code. The declaration block contains one or more declarations.

How Does CSS Work?

A style rule set consists of a selector and declaration block. You might be wondering how this CSS code is actually applied to HTML content, though. CSS code (or a style sheet) can be external, internal, or inline. Properties are things like font size, color, and margins, while values are the what is css settings for those properties, and you can change these by applying changes to the selector. For example, “background-position,” “border-color,” “border-style,” and “border-width, “and “text-align” are properties and “top,” “red,” “dotted,” “thick,” and “left” are values, respectively.

In addition to these simple attributes, there are more sophisticated CSS instructions for inserting shadows in text, adding filter functions for images and highlighting forms and other elements. This language can be used to create both simple and complex websites. In order to understand how CSS works, it is important to understand the basics of HTML. Try adding a rule to make a span red if it is inside a paragraph. You will know if you have it right because the span in the first paragraph will be red, but the one in the first list item will not change color. With a simple change of one line, a different style sheet can be used for the same page.

If you or your team is working on a large project or has a large company website, standardization of style will be important. Keeping the style separate from the structure means that global style changes can be done efficiently and more accurately than with an internal style sheet. For example, you could use the color property to change the text color of an element or the font-family property to change the font of an element. Multiple declarations can be added within the same declaration block by separating each declaration with a semicolon.
