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.
The good news is that, except for Internet Explorer, you can create more semantic markup by using the new HTML5 elements — even in browsers which don’t officially support them. Just remember to set the correct display mode: block. The following snippet should reference all necessary elements:
article,aside,details,figcaption,figure,
footer,header,hgroup,menu,nav,section {
display: block;
}
The article goes on to detail HTML5 Shiv, Modernizr, Selectivizr and other great tools that you can use to move into HTML5 and CSS3. Enjoy!
