How to add text background-color?

[dsantiago]

I used the #block tag but it adjust to full line, how to have background-color only for a specific phrase?

[PgBiel]

Use #box instead, e.g.

Text #box(fill: red)[this is red]this is not

[dsantiago]

Tried: #box(fill: red)[#lorem(30)]

Too bad it's a box, it's not related to the text and does not stop at the text end.

Oh, I see what you mean - you want background that adjusts to the text. Right now this isn't natively supported, but here's a rough hack:

#[
   #show regex("\\w+|[^\\s]"): box.with(fill: red)
   #show " ": box.with(fill: red, width: 2pt)
   #lorem(30)
]

(Places every word - or, otherwise, character - in an individually filled box, with a special case for space (a box with just a space and auto width is automatically collapsed))

This should get better in the future - please open a feature request issue for this.

Tried it now! The result is the expected but text changes all spacing. The better approximation was width: 2.7pt but it's still visible words mixing up. Thanks anyway.

#[
   #show regex(".*"): box.with(fill: red)
   #show " ": box.with(fill: red, width: 2.7pt)
   #lorem(30)
]

Just to note, found the point why the text changes so much, my text property is set with hyphenate: true and with box property the words are justified together ofc.

For further tests use:

set text(size: 12pt, hyphenate: true)
#[
   #show regex(".*"): box.with(fill: red)
   #show " ": box.with(fill: red, width: 2.7pt)
   #lorem(30)
]

Gotcha. De nada, camarada!

Have there been any developments here? I'm still looking at how to do this

[PgBiel]

Yes, this is now built-in: https://typst.app/docs/reference/text/highlight/

Should this be marked as closed or is it important as a piece of documentation to searchers?
