- Removes the plain-hover-focus mixin from active and disabled states; no need for them.
- Adds :active and :disabled since we can use button elements here, too.
- Wrap the disabled background-image override in an -gradients condition.
- No need to set hover and focus on disabled or active elements. Disabled has no interactivity and active will inherit the focus.
- Also removes two now unused vars.
- removes original outline removal (hah)
- replaces it with an explicit `outline: 0` on `.btn`
- instead of replicating `:hover` for `:focus`, uses custom and themed `box-shadow` for an "outline"
- not mapped to the `$enable-shadows` variable because accessibility
Trying to simplify our output here by revamping these selectors. We overcomplicated things by setting hover styles for nearly every state (disabled and active included), and we set them in the wrong order.
This commit does the following:
- Reorders states so disabled comes before active, thereby removing the need to set disabled-active styles.
- Removes all focus and hover styles from disabled states as those will naturally inherit from the default button state.
- Renamed `.open` to `.show` to fix dropdown toggle highlighting.
- Tweaked some indendation in the Sass.
Fixes#21135.
There's a height mismatch here because we're setting padding on the labels, while inputs get padding *and* a top+bottom border. This now uses calc to determine the exact height needed to match labels to inputs.
This also fixes#21280. Previously, we were using float and clear on the individual controls, but that meant a computer height of `0` for the parent `.custom-controls-stacked`. No more problem after using flexbox though.
- we need to set margin for space between footer buttons as flexbox doesn't render HTML spaces like inline-block does
- flexbox doesn't have collapsing margins or anything, so we hack it with some :not(:first-child) and :not(:last-child) action
