If a set of style is not compactable with adaptive width, it span to its full width even when it don't need to.

If a set of style is not compactable with floating sibling(s), the element may still work well with some short content in it; in another word, it may still looks fine when its content width + margin + padding + border is lower than the "remaining width" lefted by the floating sibling(s). So we have to use Lorem ipsum (as well as a floating box, for sure) to test it.

Ideally, you may just set the widths to fixed values, and pretend nothing happens and CSS is awesome. However, the content container of MediaWiki got adaptive width, and maybe you are maintaining a MediaWiki Template, with only inline styles.

Table rows have no margin, padding or border.

Other table display values works like table rows, or won't even display its contents.

This is the end of part one. Part two will feature contain: content, width: max-content, box-sizing: border-box; max-width: 100%, display: flex, display: grid, and more, if I ever got time to work on the part two.
