Wondering if the added-in should be on top of the page in orange-navbar.md.
In carousel.md, add a tag for play/pause button. (and add it in ship list ?)
In check-radios.md, add a tag for without labels part ?
In borders.md, add a tag for variables ? (maybe on Bs)
Do we need to add a tag on dark-offcanvas ? (on Bs side ?)

EDIT: masthead.html doesn't have the same code but it might not be an issue

• Orange Navbar didn't exist in v5.1.3 so it must be on top of the page
• Carousel with pause/play button. Good catch! Added in 9671024 (also in the ship list, IDK why it wasn't there)
• Check & Radios without labels comes from Bootstrap so let's let it as it is
• Same thing for Borders CSS variables (Bootstrap)
• Same thing for Dark OffCanvas (Bootstrap)
