To make switches swipeable:

    <button>&nbsp;</button>
    <button>&nbsp;</button>
    <button>&nbsp;</button>
</div>

Creates a grid with horizontal flow and equal width columns.

<div class="grid" style="--column-gap: 0.9375rem; --row-gap: 0.9375rem;">
    <button class="x-1">x-1</button>
    <button class="x-2">x-2</button>
    <button class="x-3">x-3</button>
    <button class="x-1 2x">2x</button>
    <button class="x-1 3x">3x</button>
    <button class="x-1 start-x y-4">start-x</button>
    <button class="x-2 center-x y-4">center-x</button>
    <button class="x-3 end-x y-4">end-x</button>
    <button class="x-1 stretch-x y-5">stretch-x</button>
    <button class="x-2 bleed-x y-5">bleed-x</button>
</div>

Note that .bleed-x, which stretches an element half the way over the grid gap, depends on column-gap having been set via the custom property --column-gap.

<div class="grid" style="--column-gap: 0.9375rem; --row-gap: 0.9375rem;">
    <button class="x-1 y-1">y-1</button>

Base class for thumbnails, avatars, icons and other cases where an image replaces some semantic text. Text is hidden by pushing it outside the hidden overflow, and only the background-image, centered and ‘cropped’ via background-size and background-position, remains.
