Use the style attribute to introduce CSS styles.

<p  style="font-size:14px;color:green;">直接在HTML标签中设置的样式</p>

<!DOCTYPE>
<html>
<head>
  <meta charset="utf-8" />
  <title>行内样式</title>
</head>
<body>
     <!--使用行内样式引入CSS-->
     <h1 id="Leaping-nbsp-Above-nbsp-The-nbsp-Water">Leaping Above The Water</h1>
     <p style="color:red;font-size:30px;">我是p标签</p>
</body>
</html>

2. Internal style sheet

Write CSS code in the style tag. The style tag is written in the head tag.

Example:

<head>
   <style type="text/css">
      h3{
            color:red;
         }
   </style>
</head>

For example:

<!DOCTYPE>
<html>
<head>
  <meta charset="utf-8" />
  <title>内部样式表</title>
  <!--使用内部样式表引入CSS-->
  <style type="text/css">
    div{
        background: green;
    }
  </style>
</head>
<body>
     <div>我是DIV</div>
</body>
</html>

HTML file in the style sheet refers to the style sheet with the extension .css. There are two ways: link type and import type.

<!DOCTYPE>
<html>
<head>
  <meta charset="utf-8" />
  <title>外部样式表</title>
  <!--链接式:推荐使用-->
  <link rel="stylesheet" type="text/css" href="css/style.css" /> 
  <!--导入式-->
  <style type="text/css">
    @import url("css/style.css");
  </style>
</head>
<body>
