external css style

External css style (also called external style) is to write the css code in a separate external file. This css style file has the extension name of ".css" and is in <head> (not in <style> tag) Use the <link> tag to link the css style file to the HTML file, as shown in the following code:

<link href="base.css" rel="stylesheet" type="text/css" />

Note:

1. The name of the css style file begins with Named with English letters of meaning, such as main.css.

2. rel="stylesheet" type="text/css" is a fixed writing method that cannot be modified.

3. The <link> tag position is generally written within the <head> tag.

body { line-height: 130pt}
H1,H2,H3,H4,H5,H6 {
color: red;
text-decoration: underline;
font-family: " 黑体 "
}
b {
font-style: italic;
color: #FF3333;
text-decoration: underline
}

We see that only the < STYLE> and comment tags are missing, and the rest of the external style sheet has not changed.
