Introduction to CSS

CSS Cascading Style Sheets cascading style sheets.
The main purpose of CSS is to add various expressions (formats, styles) to HTML tags. For example: text style, background, text style, link style.

Tip: CSS is the style added to HTML tags; JS is the behavior added to HTML tags. HTML tags come first.

HTML Hypertext Markup Language: various HTML tags.
CSS Cascading Style Sheets: Styles added to HTML tags.
JavaScript script program: a program that adds HTML tags.

Let’s look at a simple example:

<!DOCTYPE HTML>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        <title>php.cn</title>
    <style type="text/css">
        h1{
            color:red;
            border:1px solid black;
            text-align:center;
            background-color:#666666;
        }
    </style>
    </head>
    <body>
        <h1>欢迎加入php.cn</h1>
    </body>
</html>
