STR:

  • visit webflow.com and scroll down until you see a blue section with white text
  • check the contrast ratio off the dimmed white text, e.g. Master

ER:

  • the contrast ratio should fail checks

AR:

  • the contrast ratio result gives AAA rating

Note: The text node is within a parent container which has an opacity: 0.1 applied.

Yeah this is tricky as the opacity overlay is applied to a container.

Priority: -- → P3
