  <h1>Targeting :first-letter disables some OpenType features</h1>
  <p>The headings below have CSS-required OpenType features enabled (Kerning, Common/Standard Ligatures, Contextual Ligatures, and Contextual Alternates), and the characters used by each heading clearly illustrate those features: Kerning is clearly evident in 'Tr'; Common/Standard Ligatures are evident in 'fi'; The string 'offi' followed by another character is a Contextual Ligature in action; And, every character of the word 'room' is replaced by a Contextual Alternate.</p>
  <p>In addition, the first letter of each heading is styled red using the :first-letter pseudo selector. This should result in the first glyph simply turning red, but instead many features are disabled in Chrome. The two words in each heading should be identically shaped and positioned, with the only difference being the color of the very first character. This expected behavior is evident in Firefox.</p>
