how to make animation, and about this,in fact it's not complicated.
First,when u write blog(make a new one or use the old),click HTML view,then put the code into it,then click again,you'll see the result.you can search the code from network or use the fllowing.
this is the background code :
<style>body {background:url("http://pic.ik68.cn/pic/C2E784BA-1DD3-42C5-B4DF-504D2144A518.gif") repeat fixed!important;}</style>
or
<style>body {background:url("http://pic.ik68.cn/pic/C2E784BA-1DD3-42C5-B4DF-504D2144A518.gif") repeat scroll!important;}</style>
u can change the picture's web site address(the green part) into the one u like.It can be static or dynamic .
And this is the flash pendant code:
<DIV id=float style="DISPLAY: block; Z-INDEX: 1; LEFT: 15px; POSITION: absolute; TOP: 30px"><EMBED id=show_swf1 src=http://imgfree.="transparent"></DIV>
it's only an example,u can change the flash and its'position.the green part can be change.
the following is some flash web site address,use to instead of the green part
