Cross Platform With jQuery Mobile & Touch
The bad old days of Windows vs. Apple are largely over (old versions of Internet Explorer notwithstanding). Most new web browsers handle HTML5 features well - and all will in the next few months!
Progressive And yet backward too!
Take advantage of progressive enhancement - using the latest/greatest CSS3 transitions, for instance - and still be backward compatible for the browsers that don't yet support features.
Customized FontsMore than Verdana & Arial!
You can import fonts with HTML 5 and make them work for all browsers - even add CSS 3 effects like glow, highlighting and drop shadow! (caution: for best results, use in moderation!)
