Since https://github.com/discourse/discourse/pull/25501 this behavior was broken. This PR attempts to fix it by being more fine grain.
Also note that this PR is moving `footer-nav-ipad` and `footer-nav-visible` to the `html` element and not the `body`. It makes more sense as we are already adding most of other global state class like `keyboard-visible` to the `html` element.
Tested on:
- chrome desktop
- safari ios - iphone
- PWA ios - iphone
- PWA ios - ipad
- DiscourseHub iphone
This commit sets a default of 0px for `--footer-nav-height` and set it only when `body.footer-nav-visible` allowing us to safely use `--footer-nav-height` wherever it will be needed if set.
A first step to adding automatic dark mode color scheme switching. Adds a new SCSS file at `color_definitions.scss` that serves to output all SCSS color variables as CSS custom properties. And replaces all SCSS color variables with the new CSS custom properties throughout the stylesheets.
This is an alpha feature at this point, can only be enabled via console using the `default_dark_mode_color_scheme_id` site setting.
- moves footer nav to the header on iPads
- disables scrolling events for iPads
- removes footer nav entirely on Chrome PWAs
- toggles DiscourseHub iOS app status bar styling (dark/light) when opening/closing lightboxes and modals
