<meta name="assert" content="This test checks the syntax allowed by rgba() function. White space characters, instead of commas, are allowed between numerical values. <alpha-value> can be omitted for rgba() function, in which case it must defaults to 100%. Finally, rgba() function can take real numbers but their computed values will be rounded to the nearest integer, with values halfway between adjacent integers rounded towards positive infinity."> | |
