[Easy Checks] - Contrast ratio ("color contrast") - Ambiguity (Normal size)

[HerinHentry]

In the What to check for section, the below statement seems a bit ambiguous:
Web pages should also have a minimum contrast by default: a contrast ratio of at least 4.5:1 for normal-size text.

CSS font-size property supports the below font sizes:
font-size: medium | xx-small | x-small | small | large | x-large | xx-large | smaller | larger | length | initial | inherit;

Browsers support : Very small | smaller | medium | large | very large

I think we need to be a bit more clear here as some websites uses 10pts, some uses 12pts.

I agree this could be more specific, it is 4.5:1 for font sizes below 24px (18pt), or below 18.5px (14pt) when bold.

Proposed revised wording:

[... all text ... a contrast ratio of at least:]

• 4.5:1 for text that is smaller than 24px (18pt) normal, or 18.5px (14pt) bold
• 3:1 for larger text
