Yes, as mentioned in my previous post, for asp textboxes you could use both width or style, for HTML text inputs you should use style, and for both asp and HTML you could set a specific class. When using style you could set the width i pixels, em, pt etc. Using width property you could use pixels and percentages.
In previous versions, as IE6, 7, 8 does not support rounded corners we are using additional HTML elements to simulate it, because of these additional HTML elements if you set the width to 100px it would be 100 in modern browsers, but more in IE6-IE8 - about 108px.
Now with the unification fix, the problem is solved.
