So, when using tabs active tab pane should have a border and padding to look like .. normal.
Here's what seems like right to me:
.tab-pane.active {
border: 1px solid $nav-tabs-border-color;
border-top: none;
padding: $grid-gutter-width / 2;
}
Seems like a matter of taste to me. I can't seem to recall or find any other requests/complaints for such styling.
You can always use a card in the tab pane or around the entire tabs widget to achieve a similar result.

I mean isn't this better:

than this?

Especially when the tab contains text (or at least starts with text).
Is this possible with cards?
Almost, if you add .card.card-block to .tab-content, but the border still requires extra tweaking.

Yeah, I agree at least some padding would be nice in that case, but implementing that properly could be fiddly.
Doing it with cards seems like tuning css with javascript :)
If this is added, it should be entirely opt-in.
Perhaps we could could add a class that would be placed on .tab-content and use a selector like .tab-pane-outline .active for the styling.
ok, opt-in is fine. It just should be there in some way.
Closing as a won't fix. There are easy padding utilities now that can accomplish all the spacing, and borders are a preference that don't need to be set initially IMO.
