Side by side

To make good use of the space on a slide, you will often want to place content next to each other. For convenience, Polylux provides the function #side-by-side for this purpose. If you used

#import "@preview/polylux:0.3.1": *

you have it directly available. Otherwise you can get if from the utils module.

It is basically a thin wrapper around the Typst function #grid but tailored towards this specific usecase. In its simplest form, you can use it as

#side-by-side[
  #lorem(7)
][
  #lorem(10)
][
  #lorem(5)
]

resulting in

As you can see, the content arguments you provide will be placed next to each other with equal proportions of width. A spacing (gutter) of 1em will also be put between them.

The widths and gutter can be configured using the columns and gutter optional arguments, respectively. They are propagated to #grid directly so you can look up possible values in its documentation (gutter and columns arguments). If not specified, they fall back to these defaults:

• gutter: 1em
• columns: (1fr,) * n if you provided n content arguments, that means an array with the value 1fr repeated n times.

A more complex example would therefore be:

#side-by-side(gutter: 3mm, columns: (1fr, 2fr, 1fr))[
  #rect(width: 100%, stroke: none, fill: aqua)
][
  #rect(width: 100%, stroke: none, fill: teal)
][
  #rect(width: 100%, stroke: none, fill: eastern)
]
