Image
One photo with an optional caption. Images fill the width of their column, so the same photo is a banner in a full-width row and a thumbnail in a quarter. Alt text is read aloud to families using a screen reader and shown when a photo fails to load; write what is in the picture.
Full width
One column across the page. The default, and what most of a site is.

Two equal columns
Half and half. Two things of equal weight, like in-house beside travel.


Wide + rail
Two thirds, then a third. The main thing on the left, something short on the right.


Rail + wide
A third, then two thirds. The rail leads; use it when the short thing matters first.


Three equal columns
Thirds. Three short things side by side. On a phone they stack in order.



Half + two quarters
A half, then two quarters. One main thing and two small ones beside it.
