BROWSER COMPATIBILITY
FOR THE CANVAS
You've come a long way with the canvas already. Now
it's time to step back and answer the question that hangs
over every new HTML5 feature: When is it safe to use it?
Fortunately, the canvas is one of the better-supported
parts of HTML5. The latest version of every mainstream
browser supports it, as shown in Table 6-1 . Of course, the
more up-to-date the browser, the better—later builds of
these browsers improve the drawing speed of the canvas
and remove occasional glitches.
