Begun as a separate working group effort,Cascasing Style Sheets-Positioning offers much more in the way of interactively:more of the D in DHTML.The basic notation of CSS-P is that an element or group of elements can be placed in its own plane above the main document.The element lives in its own transparent layer,so it can be hidden,shown precisely positioned and moved around the page with out disturbing the other content or the layout of the document.For the first time,HTML elements can even overlap each other.
A script can maka element fly around the page or it can allow the user to drag elements around the page.Content can pop up out of now where or expand to let the viewer see more content all without reloading the page or contacting the server.
As an ass-on to the CSS1 effort CSS-P functionality uses a syntax that simply extends the CSS1 vocabulary.CSS-P rules are embedded in document the same way that CSS1 rules are embedded.The W3C work on CSS-P wasn't as far along as CSS1 was when Navigator 4 had to be put to bed.Moreover,Netscape had been lobbying the standards bodies to adopt a different technique for handling content positioning involving both a new HTML tag and a scriptable object.
