This CSS: article, aside, footer, header, section { display: block; } Does not make the new sectioning elements work in IE8. It sucks but since IE8 is the highest version of IE available for Windows XP and Win7 machines still ship with IE8 installed as default, supporting this browser will continue to be critical for all consumer sites for the next several years, minimum. Besides, using: <div class="header"> Is not that bad.
