BasicDifference between HTML 5 and HTML 4
HTML4 became a W3C Recommendation in 1997. While it continues to serve as a rough guide to many of the core features of HTML, it does not provide enough information to build implementations that interoperate with each other and, more importantly, with a critical mass of deployed content. HTML has been in continuous evolution since it was introduced to the Internet in the early 1990's. Some features were introduced in specifications; others were introduced in software releases. The same goes for XHTML1, which defines an XML serialization for HTML4, and DOM Level 2 HTML, which defines JavaScript APIs for both HTML and XHTML.

HTML5 is the latest version of HTML and XHTML. It comes up with a number of features like drag and drop, multimedia, video playback, form control etc.

The internet has changed a lot since HTML 4.01 became a standard in 1999. Today, some elements in HTML 4.01 are obsolete, never used, or not used the way they were intended to. These elements are deleted or re-written in HTML5. To better handle today's internet use, HTML5 also includes new elements for better structure, drawing, media content, and better form handling.

->HTML4 has some longer tag code than HTML5. HTML5 is easy to code tag because no additional information needed to insert it.
->Audio and Video are not supported in HTML4, but in HTML5 has tag for Audio and Video like ,. ->HTML5 supports the database to store data. Like SQL Server. ->HTML5 supports the run javascript in a browser while HTML4 and another not supported it. |
lots of differences.visit w3schools for more info

HTML Version 4.0 was published in Dec '97 by the W3C.. It offers three variations: Strict, in which deprecated elements are forbidden, Transitional, in which deprecated elements are allowed, Frameset, in which mostly only frame related elements are allowed..
And HTML5 is the latest revision of the HTML standard, including many new syntactical features and several APIs that support drawing, video, audio, etc.. |

HTML5 has several goals which differentiate it from HTML4.
The primary one is consistent, defined error handling. As you know, HTML purposely supports 'tag soup', or the ability to write malformed code and have it corrected into a valid document. The problem is that the rules for doing this aren't written down anywhere. When a new browser vendor wants to enter the market, they just have to test malformed documents in various browsers (especially IE) and reverse-engineer their error handling. If they don't, then many pages won't display correctly (estimates place roughly 90% of pages on the net as being at least somewhat malformed). So, HTML5 is attempting to discover and codify this error handling, so that browser developers can all standardize and greatly reduce the time and money required to display things consistently. As well, long in the future after HTML has died as a document format, historians may still want to read our documents, and having a completely defined parsing algorithm will greatly aid this. |
thanks for sharing important information about HTML 5 and HTML 4.

HTML5 having the error handling features. This one is very useful for developrers. Browser can expose easy interfaces like calenders etc. So we no need to include js for this type of interface.

Thanks for sharing, all information i got in here is very helpful.

Nice information.Thank you for sharing!!

The main difference between XHTML and HTML4 is that all tags, once opened, must be closed.
Some of the tags that are removed from HTML5 or have different functionality in HTML5 as compared to HTML4. HTML4 contained an |
