Is there a better way to do this?

I just realized that I need to use percentages to set the width, height, left and top properties of my web controls to make my pages fit any browser window size at any screen resolution. But I have two problems:

1. Left and Top (the positioning attributes) are only available in HTML view. Can't I get these in the properties window so I can just quickly click through my form? It will take quite a while to position a lot of elements by altering tags in the HTML view. And without seeing the form, there will be a lot of trial and error.

2. Will the look of the page be silly if I use ONLY percentages? When a really small browser is opened you would see a tiny page perfectly in proportion to the window.
