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 812f7be0e9ba70c6f2a66273c3c04692...a2d87b9af1e305217ec9648d1e8a0a47 tag.

Copy code

The code is as follows:

<STYLE TYPE="text/css"> 
<!-- 
样式规则表 
--> 
</STYLE>

For example:

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

Usually write the entire 812f7be0e9ba70c6f2a66273c3c04692...a2d87b9af1e305217ec9648d1e8a0a47 structure in the ef1cac8df639bc9110cb13b8b5ab3dd7 34934661d7147ca926b095899343bad0 section of the web page. 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 3e76e57fc5dd9b761bdd2082385f4936 tag.
Suppose we save the style rules as an example.css file, we only need to add
83041f9ba485098ac35e9c4a11d887719c3bca370b5104690d9ef395f2c5f8d1 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 812f7be0e9ba70c6f2a66273c3c04692...a2d87b9af1e305217ec9648d1e8a0a47.

Copy code

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>

For example:

<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.
