How to add aero effects to controls in a webpage?
Styling form controls is a fools errand. Most of them are provided by the Operating system.
If by aero effects you mean transparency then this is easily possible with CSS3 in good browsers, and semi-transparent images in other browsers. IE6 has no native support for alpha-transparent PNGs, but using the excellent DD_BelatedPng library you can easily fix this.
