are<header>, <hgroup>, <section>,
<article>, <aside>, <video>, <audio> ,
What is the "poster" parameter?

while the video is not playing. So whatever picture you would like
to display before starting video, we can set in poster parameter as

Is it possible to tell browser to stricly render only HTML
Yes, by giving doc type i.e. <!DOCTYPE HTML>
Will browser render HTML 5 if the deprecated tags are
Yes the browser will render however the source code is not W3C
compliant for HTML 5 (http://validator.w3.org). And
to code the application to be compliant for further versions it is
preferable to avoid using deprecated tags.
With regard to storage, is the fight between the browsers db
Local storage feature is a great way to simplify and improve the
web applications and change the perspective and approach of storage
in web applications. However same as two sides of a coin, there are
pros and cons of the same.
It is purely our own skills with which we should decide how
optimally to use the new features so that we can use their power in
action as well as handle the limitations.
More about local storage
We can take up more details in upcoming seminars, however as a
quick glance HTML 5 provides several APIs like - Web Storage, Web
SQL Database, Indexed Database, and File Access. These APIs provide
different methods to store data on the user's local device, instead
of the server. This will enable user to work offline if used
correctly. Also it improves the performance of the application.
Do you have some example about browser storage usage?
There are few examples, we can take up in detail in further
Can you explain a little bit about file access and its
potential to be used as storage alternative
Again, we can take up more details in upcoming seminars, however
just to know basics it is applicable to store large content and
binary files, like images, audio, video, PDFs, etc. It gives better
performance as it is an asynchronous API. On the other end,
the support is quite limited and is only available in Chrome.

any simple way to do this?
Yes, you can change all tags with new tags as we discussed on
example over our webinar and replace CSS according to it.

Which is preferable flash or HTML5?
In terms of speed HTML5 is faster, it does not need any external
plugin and also has lesser coding to get the same output.
Performance wise is HTML5 better than flash? Are there any
disadvantages of using HTML5 over flash?
In terms of speed HTML5 is faster, however the limitations of
using HTML 5 are the higher file size as there multiple file
versions referred for broswer compatibility and no support
available for browsers like IE 7 & 8.
