Switch from SASS variables to CSS variables * Switch from SASS variables to CSS variables for most styling These are the simple cases, and the more complex ones will be covered by future commits. I’ve also replaced $fooZ ± 1 with the appropriate variable to avoid a runtime `calc()`. * Eliminate the `$style` variable 🔥 I’ve added a `--absolute` variable that’s `white` in dark mode and `black` in regular mode. * Remove `$inputFocusBorder` 🔥 * Switch the Prism styles to CSS variables * Convert `$mediumScreen` to a mixin * 🔥 `$selectionText` * Eliminate the final uses of SCSS variables I’ve dropped the 95% opacity on the background of the method source code overlay in RDoc since the difference isn’t noticeable but it makes implementation a lot easier. * Misc fixes * Extract the common variables from the two themes to a new file * Remove illegal usages of CSS variables in SCSS functions This flattens out the buttons on the settings page which makes the styles simpler (and more modern-looking IMO) and removes the box-shadow on the button, which was completely invisible to me. * Fix usages of SCSS functions in CSS variables * Use `html._theme-` selectors Eliminate `application-dark.css`; switch themes by toggling classes This also means that the Application Cache doesn’t have to get updated when toggling themes, and a new CSS file that’s nearly the same doesn’t need to be downloaded. 7 years ago
