Ofte stilte spørsmül

What is the difference between AA and AAA?
AA is the standard legal accessibility requirement most sites target. AAA is a stricter, optional level for maximum accessibility, harder to meet with brand colors.
What counts as "large text" for the 3:1 threshold?
Text that is at least 18pt (24px), or 14pt (18.66px) bold, per the WCAG 2.1 definition.
Does this check colorblind-safe contrast too?
This tool checks luminance contrast per WCAG, which helps broadly, but for color-vision-deficiency specifically, use the separate Color Blindness Simulator tool.
