CSS: Giving text lines a background-color (with configurable line padding and margin)

The gist is:

  • wrap the text with a span
  • use line-height for the spacing between lines ("margin")
  • use box-shadow to control the line background size ("padding")



span box-shadow: 0 0 0 10px #fff background-color: #fff box-decoration-break: clone # Fix Firefox line-height: 2.2


The fourth number of box-shadow indicates spread, which can be imagined as the shadow growth when moving the light source closer towards the object. The shadow in my example creates a visual padding of 10px.

Custom Padding

You can combine multiple shadows, moving each where you need the padding. Example with 7px extra padding left and right:

box-shadow: -7px 0 0 10px #fff, 7px 0 0 10px #fff

Note that this does only work with opaque colors.

Thanks to Geoff Muskett for the inspiration.

Once an application no longer requires constant development, it needs periodic maintenance for stable and secure operation. makandra offers monthly maintenance contracts that let you focus on your business while we make sure the lights stay on.
