html - Bootstrap 4 border utilities

Question

I feel like this should be obvious to find but I have not come up with anything. Bootstrap 4 has utility class for adding and removing a border, but is there support for defining the border width or style like solid or dashed?

<span class="border"></span>
<span class="border-top"></span>
<span class="border-right"></span>
<span class="border-bottom"></span>
<span class="border-left"></span>

There are some classes that changes the margins and padding such as mr-3 and pt-2.

Maybe I just need to define them myself?

Answer 1

No, there are no classes in Bootstrap 4 for border width or style.

You can simply add something like:

.border-3 {
    border-width:3px !important;
}

NOTE: !important is needed in this case because Bootstrap also uses !important in many of the utility classes like border-*.
