Inquiry

All

I've just finished the basic layout of my site and have a question:

I've noticed that the site doesn't display the same on a Mac vs. Windows
localhost. Also, when I try to expand the site using ctrl + to enlarge the fonts
it separates and pics stay the same static size.

I thought about using Wordpres/Drupal in that their themes display the
same on any PC and do enlarge/float.

I've also research floating vs static webpages and am using the CSS value
@ the beginning of body:

<div style="width:100%">

and at the end of body:

</DIV>

with no results.

Is there a setting or code that I can implement that can help with this.
I really enjoy the voda software in that I have created a website that I
really like.

I don't want my site to be boxed in a wordpress/drupal format limiting my
creative ideals.

Any help would be appreciated.
