* Dynamic tabs: use buttons rather than links
- change docs
- add mention that tabs should be <button> elements
- tweak styles to neutralise border and background
* Update js unit and visual test accordingly
- replace links with buttons
- make one specific test that uses links instead of buttons, as we still want to support it despite it being non-semantically appropriate
- Leaving a couple of tests for now. The test for removed tabs should be redone so that tabs are removed programmatically (as the approach of having that close button inside the link is invalid and broken markup). The test for dropdowns should be removed together we actually ripping out the handling for dropdowns in the tab.js code (arguably a breaking change, though we discouraged this for a few versions and effectively "deprecated" it)
* Add isolation:isolate to prevent focus being overlapped
https://github.com/twbs/bootstrap/pull/32630#issuecomment-756015766
Replaces #30498 by adding four new null default variables for .nav-link. Doesn't carry over font-style from the original PR though since that's rarely used, at least by default Bootstrap. Nullifies all values from that PR, too, since we count on some basic inheritance here and don't need color by default.
- Use a semitransparent gradient from light to dark which works on any background-color
- Store the gradient as a custom property (--bs-gradient)
- Remove `.bg-gradient-*` variants in favour of `.bg-gradient` which works even when `$enable-gradients` are enabled
- Add gradients to navbar, active page links and badges when gradients are enabled
Previously deprecated in v4.x, this clears out the now unused Sass option and removes some unused mixins. Arguably we could remove more, but I like the hover-focus mixin and we make extensive use of it across the project.
- Justified and fill nav variants need .nav-item classes on the anchors in addition to .nav-link
- Fix broken styles for the .nav-justified class which wasn't actually doing what we needed it to
- 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.
Given move to flexbox, we can make this available for everyone and clean it up some.
- Simplifies the `.nav-justified` styles to build on the flex-powered `.nav` base class.
- Adds the `.nav-fill` to make nav links fill available horizontal space, but not equal width.
- Set an explicit `display: flex` on the base `.nav` class and remove the floats/clearfixes from our navs.
- Set some global styles for `.nav-link`, a departure from the previous solution that featured no predefined padding.
- Move `.nav-link` from `inline-block` to `block` given this setting was added for our tabs and pills anyway.
- Remove horizontal margin from nav tabs; let folks set that on their own from now on.
