As looking around the internet I am not able to find the desired comparison of HTML5 and standard HTML4. I know some of advantages of HTML5 like multimedia and new components etc. But I am looking for a nice comparison of both of these. For example I have following questions in my mind.
- What are the major advantages of HTML5 over standard HTML4 (I know of many)
- What are disadvantages of using HTML5 (Except it does not work before IE9)
- What are the advantages and disadvantages using HTML5 with CSS3 over standar HTML4 with CSS.
Here I am looking for both the advantages and disadvantages of using HTML5 and CSS3.
Thanks for time.
In short:
Advantages:
Disadvantages:
First, it’s key to remember that the language itself is not considered finished. Thus, HTML5 is a continuation of earlier versions and is considered an improvement of the language.
As you alluded in your question, the major disadvantage of HTML5 is that it’s only supported by modern browsers (see http://html5test.com/). So if your target audience does not have access to a modern browser, HTML5 would definitely be a disadvantage. This is also the major disadvantage of using CSS3.
The advantages certainly outweigh the cons. This is an excellent resource that outlines many of the differences and advantages of using HTML5 – http://dev.w3.org/html5/html4-differences/ This site has the major advantages of CSS3 over CSS – http://www.magentojunction.com/blog/advantages-of-css3-over-css/
