The World Wide Web is an evolving tool, it is again starting to take a great tweak, which improves the way graphics; text and multimedia are presented. It’s everywhere, it’s coming, and you want to know everything you can before it’s old news. We are talking about HTML5 and CSS3!
HTML5 and CSS3 (Cascading Style Sheets) are changing the way websites are being shown. The way HTML5 and CSS3 work is very similar to flash. Text can appear in very different ways, such as diagonal, with transparency, and even with different spacing or colors.
Is HTML5 and CSS3 the new Flash? Yes and No, because they can do a lot of the same things that flash does, but they don’t replace it. See it as an improved version of HTML. The good news is that it works perfectly with mobile technologies such as iPad, iPhone and Android.
The only issue is the compatibility with Internet Explorer. However, it works perfectly with Firefox, Safari, Opera and Chrome.
This is the best example of HTML5: http://www.romancortes.com/ficheros/meninas.html#
