You can click/tap on “Acid3” after the test is done and get some details. E.g. on my phone (iPhone, up-to-dare, I think) which scored 98/100 I get: Failed 2 tests. Test 23 failed: expected '14' but got '5' - wrong exception for createElementNS('null', ':div') Test 25 failed: wrong exception Total elapsed time: 0.49s The first one means it passed invalid parameters to createElementNS and expected a NamespaceError (14) exception but an InvalidCharacterError (5) exception occurred instead. (I’m waiting at the drs office, and am happy to pass the time looking up error codes.)
