'[l[http://en.wikipedia.org/wiki/Html5[HTML5] battles on BotB are the successor to '[l[http://battleofthebits.com/lyceum/View/html%20(format)[HTML battles] and, as such, are similar to them whilst incorporating many of the new standards of the modern web, most notably the tags of the massive upgrade that is HTML 5.
Often, your submission will rely heavily on using and abusing JavaScript to the fullest extent you can manage within an hour. More likely than not, the host will allow for external JavaScript libraries (eg. jquery, vanilla.js, AngularJS) to speed up production and add improved functionality to your websites.
'[#[Overview]
In HTML5 battles, '[[BotBr]s code something from scratch in an hour using the HTML language. Cascading Style Sheets (CSS) and JavaScript (ask your host if they allow '[l[http://jquery.com/[jquery] if you want to use it) are permitted; Flash, Java, and anything else that requires a plugin are not (video and audio tags ARE allowed however, this '[o]is'[/o] HTML5 afterall). The submitted file must either be a standalone .html file or a .zip file containing the main .html file and other assets.
All resources (images, stylesheets, JavaScript, etc.) used within the entry must be the author's own work (and, in the case of '[[OHB]s, created during the entry period). Hotlinking to files on the Internet is prohibited, since it wastes bandwidth from the host, is prone to breaking, and would likely break one of the other rules as is. This means that resources utilizing server connections (such as PHP code) is forbidden as well.
'[#[New Additions]
HTML5 has different standards than HTML; adding and removing features that separate it from the past allow it to be the standard of the modern web. Here's some essential info for some of these standards.
