CSS Syntax

css

CSS (Cascading Style Sheets) is a stylesheet language that is used to control the appearance and layout of web pages. It allows you to specify the styles for HTML elements, such as fonts, colors, and margins, and apply those styles consistently across multiple web pages.

CSS has a simple and flexible syntax that consists of a set of rules, called “selectors”, that define which elements on a web page the styles should be applied to, and a set of declarations, which define the styles themselves.

Here is an example of a basic CSS rule:

h1 {
    color: red;
    font-size: 24px;
    margin-bottom: 10px;
}

In this example, the rule is applied to all h1 elements on the web page. The rule consists of a selector (h1) and a set of declarations (color: red; font-size: 24px; margin-bottom: 10px;). Each declaration consists of a property (such as color or font-size) and a value (such as red or 24px).

You can apply CSS styles to a web page by including them in a style element in the HTML document, or by linking to an external CSS file using the link element.

Here is an example of how you can include CSS styles in an HTML document:

<!DOCTYPE html>
<html>
<head>
    <style>
        h1 {
            color: red;
            font-size: 24px;
            margin-bottom: 10px;
        }
    </style>
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>

And here is an example of how you can link to an external CSS file:

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="style.css">
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>

In this example, the style.css file contains the CSS styles that are applied to the web page.

Note: CSS supports a wide range of selectors and properties that you can use to control the appearance and layout of web pages. You can learn more about the CSS syntax and how to use it by reading the CSS documentation and tutorials.
