Solution 1:

In v2, there isn't anything built-in for that much vertical space, so you'll want to stick with a custom class. For smaller heights, I usually just throw a <div class="control-group"> around a button.

Solution 2:

Wrapping works but when you just want a space, I like:

<div class="col-xs-12" style="height:50px;"></div>

Solution 3:

In Bootstrap 4/5 there are spacing utilites (BS4, BS5).

Excerpt from the documentation:

Spacing utilities that apply to all breakpoints, from xs to xl, have no breakpoint abbreviation in them. This is because those classes are applied from min-width: 0 and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.

The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.

Where property is one of:

  • m - for classes that set margin
  • p - for classes that set padding

Where sides is one of (please note differences in BS4 and BS5):

  • t - for classes that set margin-top or padding-top
  • b - for classes that set margin-bottom or padding-bottom
  • l - for classes that set margin-left or padding-left (Bootstrap 4)
  • s - for classes that set margin-left or padding-left (Bootstrap 5)
  • r - for classes that set margin-right or padding-right (Bootstrap 4)
  • e - for classes that set margin-right or padding-right (Bootstrap 5)
  • x - for classes that set both *-left and *-right
  • y - for classes that set both *-top and *-bottom
  • blank - for classes that set a margin or padding on all 4 sides of the element

Where size is one of:

  • 0 - for classes that eliminate the margin or padding by setting it to 0
  • 1 - (by default) for classes that set the margin or padding to $spacer * .25
  • 2 - (by default) for classes that set the margin or padding to $spacer * .5
  • 3 - (by default) for classes that set the margin or padding to $spacer
  • 4 - (by default) for classes that set the margin or padding to $spacer * 1.5
  • 5 - (by default) for classes that set the margin or padding to $spacer * 3

So to have some extra vertical space above and below an element you would use my-5 class.
