Bug 70325 – Web Inspector: CSS background-image applied inline shows a warning, but still works.

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Alexander Pavlov (apavlov)]

1. declare a CSS background-image inline (within the style
attribute of a <tag>)

What do you see instead?

Chrome's Developer Tools shows a warning icon
and strikethrough of the rule, yet the image still renders fine. No
warning is shown if the background-image is declared as a CSS rule.

Changing the inline rule from 'background-image' to just
'background' (but leaving only the url value) causes the warning to go
away. This seems very strange and I am curious if it is a bug.

Please see this example where there are 3 background-images (1 CSS
rule, 2 inline). The 2 inline have warnings. Change one of them to be
just 'background' and the warning will go away.

Please do not mix semantics changes with the lint fixes.

I would add CSSStyleSheet* contextStyleSheet parameter into the parseDeclaration and make existing call sites (~3 of them) explicitly pass either parent stylesheet or 0 there.

These are false positives (AFAIK, the lint fix is in the works).
