  <meta content="The :first-line pseudo-element can be used and will apply onto an :hover pseudo-class." name="assert" />

  <style type="text/css"><![CDATA[

  <p>Test passes if "Text sample" becomes white on blue background when the mouse cursor hovers over it or hovers over its right-hand side.</p>
