== Syntax ==
#REDIRECT [[Differences from HTML4]]
 
* HTML5 specifies its own syntax rules authors have to follow. These syntax rules are compatible with the XHTML syntax rules althoug this does not imply that parsing such a document with an HTML parser will give the same result as parsing it with an XML parser.
 
* HTML5 defines its own parsing rules (including "error correction") for text/html resources and no longer assumes SGML features are supported.
 
== New elements ==
 
=== Document Structure ===
 
* article
* aside

* m

* source
* time
* video
 
=== Applications ===
 
* canvas

== Changed elements ==
 
These elements have a new meaning in HTML5 which is incompatible with HTML4. The new meaning better reflects the way they are used on the web or gives them a purpose so people can start using them.
 
* b
* hr
* i
* menu
* small
* strong
 
== Dropped elements ==
 
That these elements are dropped means that authors are no longer allowed to use them. User agents will still have to support them and HTML5 will probably get a rendering section in due course that says exactly how. (isindex for instance is already supported by the parser.)
 
* acronym (use abbr instead)
* applet (use object instead)
* basefont
* big
* center
* dir
* frame
* frameset
* isindex
* noframes
* noscript (only dropped in XHTML5)
* s
* strike
* tt
* u
