Text contrast (text-contrast)

Text smaller than 18pt (or 14pt bold) must meet a contrast ratio of 4.5:1 against its background.


Insufficient text contrast with opacity 2.1:1:

This paragraph uses black text with 30% opacity on a white background. The effective contrast ratio is approximately 2.1:1, which fails WCAG minimum contrast requirements for normal-sized text.


Some text in English

Note: Possible to implement because rendered text and background colors (including opacity) can be computed programmatically to calculate contrast ratio and compare it against WCAG thresholds.
