Tips & Tricks

Historically, this element has commonly been used solely for its font sizing features and even though the character formatting elements BIG, FONT and SMALL are now available, headings can still be used for this purpose (and Headings are still more widely implemented than these other elements.)
Mixing Headings and FONT elements (especially those with SIZE attributes) is possible, and is actually a good idea for backward compatibility.

Browser Peculiarities

Mosaic has always supported another heading size, H7, which has a lower importance than H6 and is rendered smaller.
Netscape versions 1.0-1.22 only understood ALIGN values of LEFT and CENTER. Support for ALIGN=RIGHT began in version 2.0.
The 'justify' value of the ALIGN attribute is currently only supported in the 4.0 Beta 2 and above versions of Netscape and Internet Explorer.
