Bug 189673 – Web Inspector: move DarkMode.css rules into appropriate CSS files

• Component: Web Inspector
• Status: RESOLVED FIXED

[Nikita Vasilyev]

Move all CSS rules from DarkMode.css to appropriate CSS files, then remove DarkMode.css.

DarkMode.css consists of many sections, e.g.:

    /* ImageResourceContentView.css */
    .content-view.resource.image {
        background: var(--background-color-content);
    }

This CSS rule, for example, should move to ImageResourceContentView.css.

Well, this broke a few things since the order of the style rules changes. Priorities of some CSS rules need to be adjusted.

r=me, with a few minor things.

Is there a bug that can be referenced here?

> Source/WebInspectorUI/UserInterface/Views/Main.css:136
> +    background-color: var(--background-color-content);

Can this change go in https://webkit.org/b/189766 instead?

> Source/WebInspectorUI/UserInterface/Views/SearchSidebarPanel.css:82
> +@media all {

So the banner style applies to both light and dark mode? Why do we need "@media all" here?

Is there a bug that can be referenced here?

> +    /* FIXME: Use CSS4 color functions once they're available. */

Could you file a bug for this and add a reference?

> Source/WebInspectorUI/UserInterface/Views/Variables.css:266
> +        /* FIXME: these properties are duplicated so that they have higher specificity than WebKit's stylesheet.

If the workaround isn't temporary, you can drop the FIXME from this explanatory comment.

Whoops! Should be prefers-dark-interface!

AFAIK, there no syntax for this that vendors agreed on. I'll just remove this comment.
