Javascript auto-scroll couplet advertisement code sharing

This couplet advertisement is different from other advertisements. This is the two couplet advertisements that were first not seen when the page was loaded, and then quickly flown in from the left. Let's take a look at the couplet advertisement effect code.

 

The Code is as follows:

<P>

<Meta content = "text/html; charset = gb2312" http-equiv = "Content-Type"/> <style type = "text/css">

 

. Shuoming {margin-top: 20px; border: 1px solid # ccc; padding-bottom: 10px; width: 600px; margin: 0 auto ;}

. Shuoming dt {height: 30px; line-height: 30px; font-weight: bold; text-indent: 10px ;}

. Shuoming dd {line-height: 20px; padding: 5px 20px ;}</style> </p>
