For many elements Konsta UI uses so called "hairlines" instead of usual CSS borders.

Hairlines are made with :after and :before pseudo elements. This method allows to have true 0.5px and 0.33px wide "borders".

Add Hairlines

To add hairline we need to use .hairline-[side] classes:

Class
`.hairline-t`	Add top hairline
`.hairline-r`	Add right hairline
`.hairline-b`	Add bottom hairline
`.hairline-l`	Add left hairline

Note, hairlines use absolute positioning, so make sure element with hairline has absolute, fixed or relative position

For example:

<!-- add bottom hairline to the element -->
<div class="relative hairline-b">...</div>

Remove Hairlines

To remove hairline we need to use .no-hairline-[side] classes:

Class
`.hairline-t-none`	Remove top hairline
`.hairline-r-none`	Remove right hairline
`.hairline-b-none`	Remove bottom hairline
`.hairline-l-none`	Remove left hairline

Hairline Color

Hairline color is also customizable with .hairline-[color] classes:

Class
`.hairline-[color]`	Set hairline color

For example:

<!-- add bottom hairline with red-500 color to the element -->
<div class="relative hairline-b hairline-red-500">...</div>

Hairline Transition Duration

To control hairline transition duration we can use .hairline-duration-[duration] classes:

Class
`.hairline-duration-[duration]`	Set hairline transition duration

For example:

<!-- add bottom hairline with red-500 color to the element, and change its color to blue-500 on hover -->
<div
  class="relative hairline-b hairline-red-500 hairline-duration-300 hover:hairline-blue-500"
>
  ...
</div>
