Size mixin

[MartijnCuppens]

The size mixin is not documented in the docs.

bootstrap/scss/mixins/_size.scss

Lines 1 to 6 in 29f178d

	// Sizing shortcuts
	@mixin size($width, $height: $width) {
	width: $width;
	height: $height;
	}

Shall we:

• document this
• or remove the mixin (width and height are not the most complex properties to remember)

I think we should drop this, but let's hear @mdo's thoughts too.

I personally find it very useful, especially in complex SCSS files.

Not sure why anyone would want to drop this? It's not like it increases build sizes or anything. I find it cleans up the code a bit actually.

[mdo]

Yeah, it doesn't hurt anything having it, but it does apparently need documenting.

[kevinruscoe]

Hmm, at the moment there's no dedicated place in the documentation for the sass mixins. They are mentioned a couple of times but under their section (i.e. grid and float).

I think we would have to add a root level doc for the mixins because I'm not sure it fits anywhere else.

I'm closing this.
Discussion about mixins documentation here: #25977
Once we have an overview of all the mixins, we can figure out which mixins need to be deprecated in the future.
