I would like to know if there is a way to use a particular css page as styling for a tag. For example, instead of
<div class="header" style="position: absolute; text-align:left; right: auto; margin: 0 auto 20px; z-index: 1; width: 60%; height: auto; left:9%">
Is there a way to specify style.css for the div tag?
For example,
This style.css must ONLY apply to the div tag above.
Also, is it possible for all tags contained within that div tag to follow the same specified css page?
