HTML and CSS Reference
In-Depth Information
• The benefit of events and sophisticated attributes, such as
style
, is unclear for
browsers that would use content within
<noframes>
, given that older browsers
that don't support frames probably would not support these features.
<noscript> (No Script Support Content)
This element is used to enclose content that should be rendered on browsers that do not
support scripting or that have scripting turned off.

class="class name(s)"
dir="ltr | rtl"
