For more contexts, see bug 1659444. Query that currently captures all of these: https://searchfox.org/mozilla-central/search?q=%25if&path=css . There are broadly the following cases: 1. `%if 0`, especially for license headers. These can just be converted to normal comments. 2. CSS that can move from "shared" files to OS-specific files 3. CSS using `MENUBAR_CAN_AUTOHIDE`, which can probably switch to using an attribute on the root (moving the ifdef into browser.xhtml, where it's already used anyway) 4. CSS that is platform-specific and can switch to using an attribute, media query, or other mechanism 5. CSS that is inside the UA stylesheets. There we can use something like: ```css /* %ifdef MOZ_WIDGET_GTK */ ... /* %endif */ ``` to hide the preprocessor markup from a linter.
