Bug 141262 – Web Inspector: if a known CSS property has an unsupported value, only strikethrough the value

• Component: Web Inspector
• Status: RESOLVED FIXED

Current appearance

Use case: accidentally put 'visibility: none;' in the stylesheet. The whole line is strikethrough with red. But we know 'visibility' is a real property (cross references with CSS.getSupportedProperties), so just cross out the property value.

Do we need to do anything special for properties that can have a "-webkit-" prefix or not? Like transform can, and some others.

Will this marker get cleared when edits are made to make the value valid?

I tested this with a few different "-webkit-" prefixed properties and it worked correctly without any issues, so no.  As far as I understand, the property name includes "-webkit-" so it will match with that in mind.  If I had used canonicalName, then this would be a problem as it strips prefixes.

Yes the marker is redrawn every time the editor is updated, so if the property is no longer invalid it will not draw.

Array.prototype.includes?

This name reads weird to me. How about isValidPropertyName or isSupportedPropertyName?

Yes!
