If i made flash banner in Adobe Flash CS4, how we add it in website which is based on html and CSS.
you will need to copy the swf file + any other script associated (can leave .fla) to the website server, then use the <embed> or <object> tags to add to webpage:
refer to adobe help for the tags: http://kb2.adobe.com/cps/415/tn_4150.html
u can add ur flash banner with adobe dreamweaver. it's a good software for adding flash base bannar in website
publish your flv file with html. then you can see the a html file will be created. view the source of the page. then copy only code of between <object> </object> tag.
then paste that code where you want to see in you site...
The simplest way is to just google/bing/whatever for the proper html to put the banner into your site. Using Dreamweaver is simple and easy, but putting a flash movie in a site with using Dreamweaver is horrendous on the code side-a TON of extra crap code you don't need, id's are ridiculously long-20+ characters, and the code the DW writes is just plain ugly.
