If you look at a shorthand CSS property in the web inspector, it will have a dropdown displaying the proper longhand syntaxes. For example, background: blue url(img/bg.png) no-repeat 5px 5px); expands out to its component background-image, background-color, background-positon..., and background-repeat. However, these expanded properties are non-editable. Editing them would be quite useful, as it could optimize css debugging on particularly complex properties. Reproduction: * Open web inspector, and select an element * Add a shorthand syntax, for background * Click the arrow next to the background entry to view the sub-properties * Attempt to edit said properties Desired behavior: * Properties should be editable, and update the shorthand syntax appropriately.
