Summary of four methods to add CSS style sheets to web pages

Summary of four methods for adding CSS style sheets to web pages. You can choose your favorite method according to your needs.

1. Use the STYLE attribute: Add the STYLE attribute directly to individual component tags.

The advantage of this usage is that the style can be flexibly applied to each label. But the disadvantage is that there is no "unity" in the entire document.

2. Use the STYLE tag: Write the style rules in the tag.

The code is as follows:

<STYLE TYPE="text/css"> 
<!-- 
样式规则表 
--> 
</STYLE> 
例如： 
<STYLE TYPE="text/css"> 
<!-- 
BODY { 
color: BLUE; 
background: #FFFFCC; 
font-size: 9pt} 
TD, P { 
COLOR: GREEN; 
font-size: 9pt} 
--> 
</STYLE>

Usually the entire structure is written in the section. The advantage of this usage lies in the uniformity of the entire document. As long as there is a declared component, the style rule will be applied. The disadvantage is the lack of flexibility in individual components.

3. Use the LINK tag: Write the style rules in the .css style file, and then introduce it with the tag.
Suppose we save the style rules as an example.css file, we only need to add
The style specified in the style file can be applied. Usually the LINK tag is written in the section of the web page. The advantage of this usage is that you can assign several documents to which the same style rules apply to the same style file. The disadvantage is also the lack of flexibility in individual files or components.


4. Use @import to introduce: It is very similar to LINK usage, but must be placed in .

The code is as follows:

<STYLE TYPE="text/css"> 
<!-- 
@import url(引入的样式表的位址、路径与档名); 
--> 
</STYLE> 
例如： 
<STYLE TYPE="text/css"> 
<!-- 
@import url(http://yourweb/ example.css); 
--> 
</STYLE>

It should be noted that the semicolon at the end of the line is absolutely essential! In this way,
@import url(http://yourweb/ example.css);
can also be added to other styles to call.
