Acid2

Called Acid2, a website test would check,
Exposing flaws a browser may conceal,
By testing all the features' newest tech.
A garbled image: errors thus reveal.

Cascading style sheets to frame a face,
And object eyes with alpha layers shade,
And padding, margins, borders, rightly place.
The nose glows blue: on cursor hover stayed.

Safari was the first to pass the test.
A year passed: Opera and Mozilla next.
In two more years, last March, it joined the rest,
Explorer 8, at last, passed all the checks.

Each mainstream browsers now with all complies,
"To Acid3," the web consortium cries!
