Auto Width Feature
Auto Width automatically adjusts your image size based on the content block and available space.
To Enable Auto Width

- Turn on the Auto Width toggle
- Your image will automatically fill the content block

When to Use Auto Width
- Your image is smaller than the content block
- You want consistent spacing in your layout
- You're using images of varying sizes
