textbox shading

[Peter Ghali]

Hi all,

Does anyone know how to apply a colored shading to the active element (ie:
The textbox that currently has focus) in an InfoPath form? As the user tabs
around my form, I want the background of the active textbox to be shaded
yellow.

Since my form is huge and changes frequently, I'd like to find a way to do
this without using conditional formatting on each textbox--perhaps by
applying a css style to the view (.xsl file).

Thanks in advance.
