Line Height

Utilities to change an element's line-height.

Relative Line-Heights

Use d-lh-{n} to change an element's line-height relatively. This means no unit is set with the line-height. Instead the line-height value is a multiple of the font-size.

<p class="d-lh-unset">...</p>
<p class="d-lh-100">...</p>
<p class="d-lh-200">...</p>
<p class="d-lh-300">...</p>
<p class="d-lh-400">...</p>
<p class="d-lh-500">...</p>
<p class="d-lh-600">...</p>

Fixed Line-Heights

Use d-lh{n} to fix an element's line-height. This allows you to target a specific line-height based on the font-size. For example if a target 20px line-height is desired and the current font-size is 14px, apply .d-lh6 to achieve this target (14px font-size + 6px = 20px target line-height).

<p class="d-lh0">...</p>
<p class="d-lh1">...</p>
<p class="d-lh2">...</p>
<p class="d-lh4">...</p>
<p class="d-lh6">...</p>
<p class="d-lh8">...</p>
<p class="d-lh12">...</p>
<p class="d-lh16">...</p>
<p class="d-lh20">...</p>
<p class="d-lh24">...</p>
