01

Use blobs as layers

A blob works best behind or beside content, where its shape can create balance without becoming another component to understand.

  • Keep the shape out of the content reading order.
  • Use a restrained color or opacity when text is nearby.
  • Check the silhouette at the size it will ship.
02

Make the fallback intentional

Decorative SVG or CSS shapes should not be required for the page to communicate its message.

  • Provide a solid background color.
  • Respect reduced-motion preferences if the shape moves.
  • Avoid using the blob as the only boundary for important content.
Questions
Should a blob be interactive?

Usually no. Keep it decorative unless its shape is part of a real control or illustration the user needs to understand.
