    <title>CSS Test (Transforms): 'inherit' and em</title>

    <meta name="assert" content='The &apos;transform&apos; property&apos;s
    computed value (which is what&apos;s inherited if &apos;inherit&apos; is
    specified) is defined as "As specified, but with relative lengths converted
    into absolute lengths."  In this test, a parent element has a transform of
    1em with a font-size of 25px, and the child has "transform: inherit".
    Since the relative length of 1em is converted to an absolute length of 25px
    before inheritance, the child should be translated by a further 25px, for a
    total of 50px, even though its font-size is 100px.  An implementation that
    incorrectly inherited 1em without converting it to an absolute length first
    would translate by 125px.'>
