Adds a new `[grid]` tag that can arrange images (or other media) into a grid in posts.
The grid defaults to a 3-column with a few exceptions:
- if there are only 2 or 4 items, it defaults to a 2-column grid (because it generally looks better)
- on mobile, it defaults to a 2-column grid
- if there is only one item, the grid has no effect
A follow-up to #15117 and #15141. Applies the previous changes to PM-specific fields, makes the preview area take the all the available height of the composer, and unifies more spacing between composer elements.
Major changes included:
- better support for screen readers
- trapping focus in modals
- better tabbing order in composer
- alerts on no content found/number of items found
- better autofocus in modals
- mini-tag-chooser is now a multi-select component
- each multi-select-component will now display selection on one row
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
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.
Uses a thin border as indicator that element is in focus for all editable items in the composer (inputs, select kit, textarea).
Disables a default iOS style that has a blinking background color on inputs/textareas
* FIX: Perform crop using user-specified image sizes
It used to resize the images to max width and height first and then
perform the crop operation. This is wrong because it ignored the user
specified image sizes from the Markdown.
* DEV: Use real images in test
