Tips for setting uniform line-height across an entire project by adding a fixed value to the font size

I need to update line heights for a complete project. The requirement is that all line heights should equal the font size plus 4 pixels.

Is there a simple way to do this using SCSS?

Adjusting based on percentage would be easy, but the specific value is giving me trouble.

Can I apply this globally without having to specify it for each class where the font size is changed?

Answer №1

A variety of methods can be used to achieve this:

  1. $fontSize is initially set as a static px value:
$fontSize: 12px;

$lineHeight: $fontSize + 4;
  1. If your font-size needs to be calculated dynamically at runtime:
line-height: calc(1em + 4x);

An illustration utilizing the calc property;

p {
  font-size: 14px; background: yellow;
}

.lh {
  line-height: calc(1em + 4px);
}
<p class="lh">Hello World</p>
