Canvas images support inline captions — a text label that sits below the image and stays attached as you move or resize. Videos and uploaded video files take the same caption, under the card's footer.

Adding a Caption

Click the caption area below an image to start typing. The caption commits when you click away or press Escape.

Caption Behavior

• Stays attached when you move or resize the image
• Background color adapts to light and dark mode automatically
• Caption font is sized to remain readable at the image's current scale

Custom Caption Background

Change the image element's background color from the edit overlay — the caption background updates to match, so the pair stays cohesive.

Use Cases

• Label screenshots and diagrams with context
• Annotate moodboard images with source references
• Add alt-text style descriptions for board accessibility
• Number panels in a storyboard sequence
