Created attachment 467812 [details] Image of Firefox Web Inspector - Pseudo-element option Enhancement Request to Inspect Element. Safari > Inspect Element > Pseudo-element option The user can view the following: active, focus, focus-visible, focus-within, hover, target, visited. Currently, within Web Inspector, the user does not have the option to view/change styling for ::placeholder. Example: Firefox > Inspect > Style panel > Pseudo-element.
You are right. That would be a good improvement. It seems to be in the backend code of the Web Inspector according to Bug 203269 *** This bug has been marked as a duplicate of bug 203269 ***
(In reply to Nilesh Prajapati from comment #0) > The user can view the following: active, focus, focus-visible, focus-within, > hover, target, visited. > Those are pseudo-classes. `::placeholder` is a pseudo-element, like `::before`, `::after`, `::marker` and others. The UI in the Styles panel is for toggling those pseudo-classes to reveal corresponding styles. The pseudo-element `::placeholder` would not be on that list. Karl is right that not showing CSS rules that include `::placeholder` in the selector in the Styles panel is indeed a bug and duplicate of Bug 203269 which we need to fix.
