The framework is generally applied to the first page of the interface layout work. Cut a Web page into multiple page management. A frame file typically contains only the layout information of the frame and does not contain other content, and all the page effects are displayed on each frameset page. They all belong to the frame file and are independent (sideways) from each other.
<frameset rows= "10%,86%,4%" >
<!--top-->
<frame src= "Top.html#header" scrolling= "no" frameborder= "0" name= "top" >
<!--center-->
<frameset cols= "15%,85%" name= "cen" > <frame src= "lmenu.html" name= "Lmenu" > <frame src= "rmain.html" name = "Rmain" > </frameset>
<!--footer-->
<frame src= "footer.html" scrolling= "no" name= "Footer" >
</frameset>
IFrame is actually an embedded framework, is in a Web page (often has content) nested in the content of another page, the relationship between them is a parent-child relationship.
