7.0+ | 4.5+ |
"AA" |
4.5+ | 3.0+ |
"Fail" |
below 4.5 | below 3.0 |
--hints--
getContrastRating("7.5", false) should return "AAA".
assert.equal(getContrastRating("7.5", false), "AAA");
getContrastRating("4.8", false) should return "AA".
assert.equal(getContrastRating("4.8", false), "AA");
getContrastRating("4.2", false) should return "Fail".
assert.equal(getContrastRating("4.2", false), "Fail");
getContrastRating("4.5", true) should return "AAA".

getContrastRating("3.0", true) should return "AA".
