Exercise #4

Ensuring Text Legibility Over Dynamic Imagery

Placing headlines directly over photographs is one of the most common causes of WCAG contrast failure:

Tested Mitigation Techniques

  1. Directional Scrim (Gradient Mask): Apply a subtle linear gradient overlay (e.g., 0% black to 60% black) behind the text. This preserves the photo's vibrancy while guaranteeing text contrast.
  2. Solid Card Containers: House the text in an elevated, solid or frosted glass (backdrop-filter: blur) container over the image.
  3. Contrast Tint Overlay: Apply a global semi-transparent tint matching brand surface colors across the entire image.
