How do I… · Figma
Auto layout makes a frame arrange its children in a row or a column and resize itself around them. It is the difference between a picture of a UI and a UI that survives longer text.
If a text layer refuses to wrap, it is set to Hug rather than Fill. If a frame will not shrink, something inside it is Fixed. Absolute position (the icon at the top of the auto layout section) lifts one child out of the flow so you can place a badge on a corner without breaking the row.
This page is written by the people who make Open Portal: press Ctrl+Shift+O, box any part of your screen, and ask about it. Figma included — it works in every app, because it reads pixels rather than plugging into anything.
Faster than searching: box the part of your screen you cannot work out and ask about it directly — in Figma or anywhere else. Answers arrive where you drew the box.
