<div>
<div class="content wysiwyg-content">
&lt;div id=&quot;foo&quot;&gt;<br />
..... more markup .....<br />
&lt;/div&gt;<br />
<br />
Assume all CSS rules for the content inside have an id selector of &quot;foo&quot; as the prefix<br />
<br />
Examples:<br />
<br />
#foo p{...}<br />
#foo #myspan{....}<br />
<br />
Is there any way for these rules to modify/affect CSS outside of the div? Reason being I plan on pre-fixing in this fashion to all user supplied CSS rules so my main page cannot be modified (I don't want to apply !important on all of my rules). Thanks

CSS Overriding and Scope

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.
