Designing for variable browser sizes

[scottholmes]

I was recently given a criticism that a project of mine seems to be designed for "small screen". This is true as most of the work has been done on 17inch screens. I need some general advise and suggestions on what I should be most concerned about: fonts, iframe sizes, div sizes etc. I've got a pretty good idea what to do in specific situations. What I don't have is a designers eye. I've posted this query here as I'm quie sure that whatever I do will be done with AJAX.

To make web page independent of screen size, You should always make all the component of webpage in percentage size. for exp: and so on.

In this way if the screen is small or big it will adjust acording to the percentage given by you.
