Hi all ,
we are in the process to build an HTML page that contains a data capture feature.
I've been asked to provide my technical requirements.
since I'm a trainee and have no previous experience in such projects I'd like to have your advice in the requirements below.
Would anyone please check if I need to add/modify one of them.

1. The HTML page should be cross browser compatible.
2. The data capture fields should be well validated.
3. The HTML page should comply with W3C standards.

Is there any requirement should be added or the above is enough ??

Your help is really very much appreciated.

Kind Regards ,
