1849255 - [Inactive CSS] Report ignored properties on ::placeholder pseudo-elements

Status: RESOLVED FIXED

(DevTools :: Inspector: Rules, enhancement)

Description

[Sebastian Zartner [:sebo]]

The ::placeholder pseudo-element allows to be styled the same way as the ::first-line pseudo-element.

As user agents are allowed to apply any additional properties to the ones listed in the spec., the only ones that are explicitly excluded are:

• writing-mode
• direction
• text-orientation
• All CSS Inline properties (as of a CSSWG resolution)
