Not every HTML5 or CSS3 feature has widespread browser support, naturally. To compensate for this, enterprising developers have created a number of tools to let you use these technologies today, without leaving behind users who still live in the stone age.
Free for use in all web projects, professional or personal, HTML5 Reset by Monkey Do! is a set of HTML5 and CSS templates that jumpstart web development by removing the styling native to each browser, establishing basic HTML structures (title, header, footer, etc.), clearing floats, correcting for IE problems, and more.
