HTML and CSS Reference
In-Depth Information
Notes
• Each <label> must not contain more than one form field.
• The label element should not be nested.
<layer> (Positioned Layer)
This Netscape 4. x -specific element allows the definition of overlapping content layers that can
be exactly positioned, hidden or shown, rendered transparent or opaque, reordered front to
back, and nested. The functionality of layers is available using CSS positioning facilities, and
the layer element is listed here purely for historical reasons in case developers come across
pages using them.
