Use a js program to implement the animation function

Since ie changed the display mode of flash, flash has suddenly become a chicken rib.
Many websites have removed the previous flash Animation and switched to a js program to implement the animation function.

The same is true for the csdn homepage .. I was bored and wrote one by myself. The features are as follows:

1. search engine friendly
2. It is friendly to artists, because the data and code are separated. if Javascript is not understood at all, you can use fontpage to modify the animation content.

You can save the js Code as a file and then <script src = "1.js"> </script>, without having to change the code to a letter.
You can achieve animation in multiple pages.


The Code is as follows:

Copy codeThe Code is as follows:
<Style>
# G_div {text-align: right; overflow: hidden}
. B {width: 24px; height: 16px; background: #737373; font-size: 14px; font-weight: bold; color: # fff; text-decoration: none; margin-left: 1px}
. B: hover {width: 24px; height: 16px; background: #780001; font-size: 14px; font-weight: bold; color: # fff; text-decoration: none; margin-left: 1px}
. Bhover {width: 24px; height: 16px; background: #780001; font-size: 14px; font-weight: bold; color: # fff; text-decoration: none; margin-left: 1px}
