274847 - External .css containing HTML tags only partially recognized

Status: VERIFIED INVALID

(Firefox :: General, defect)

Description

[Andreas Höfler]

I know, it's not correct external CSS, but if an external css-file with the content:

  <style type="text/css">
  <!--
  .dummy { color: red; } 
  .dummy2 { color: blue; }
  -->
  </style>

is referenced with <LINK ...> then the .dummy2-Style is usable in the including
file whereas the .dummy-Style is not. Checked with DOM-Inspector.

Shouldn't the content in the .css be either fully ignored or fully recognized?
Partially presence of the styles easily leads to confusion.

That's because your improper inclusion of HTML created a CSS selector called:

<style type="text/css"><!--.dummy

Which obviously does not exist in your HTML code.

But in that case the DOM Inspector (Document Stylesheets) should display two CSS
styles:
- <style type="text/css"><!--.dummy
- .dummy2

but it only lists .dummy2

Could this perhaps be a bug in the DOM Inspector then?
