HTML and CSS Reference
• HTML5 includes the iframe but does not include standard frames.
• When a browser does not understand an <iframe> tag, it displays the text included
within it as an alternate rendering.
<ilayer> (Inflow Layer)
This Netscape 4-specific element allows the definition of overlapping content layers that
can be positioned, hidden or shown, rendered transparent or opaque, reordered front to
back, and nested. An inflow layer is a layer with a relative position that appears where it
would naturally occur in the document, in contrast to a general layer , which might be
positioned absolutely, regardless of its location in a document. The functionality of layers is
available using CSS positioning, and page developers are advised not to use this element. It
is presented solely for historical purposes in support of existing pages.
