I want to prepare for HTML 5 and start playing with it. Should I install it or something before using it? How it works? Now I am on shared hosting.
HTML5 is not a server technology. All you need to get started is a browser that supports HTML5.
See these pages for HTML5 support in different layout engines:
http://wiki.whatwg.org/wiki/Implementations_in_Web_browsers http://en.wikipedia.org/wiki/Comparison_of_layout_engines_(HTML5)
HTML5 - XHTML 1.1 HTML 4.x? ( , ). HTML 5, .
HTML 5 /: (HTML5)
HTML 5 : HTML 5
. -. , - -, HTML5. .
HTML. HTML5 - . 18 2011 W3C , HTML5.
<!DOCTYPE html> - HTML 5, .
<!DOCTYPE html>
Even if you have not added doctype, HTML 5 tags still work (if supported).
No.
Like all HTML, it has nothing to do with hosting (unlike PHP, etc.).
Just create your page with HTML5 elements and upload it to your hosting. You can then view the page in your browser if the browser supports HTML5, of course.
