How to make text fields wider

Thanks for the plugin. New version has me stumped. I’m not a CSS or PHP expert. Apologies in advance for my novice question.

I’m using the 2010 theme. I’ve read your FAQ. The “How to set or reset the styles of the form field” has a tantalizing graphic which says “Let’s make this wider”. Sadly the text in the FAQ doesn’t actually explain how to do it.

I’ve been playing with your new Styles tab. So far I’ve been able to work out that the first style (Form DIV) is value that controls the overall width of the form. So I’ve increased this to a suitably big number of px. I also changed the “Input Text Area Fields” to have a wider max-width and that’s worked for my Text Area field. The last thing I want is to increase the width of the Text fields (“Let’s make this wider”) but I don’t know how. I’m pretty sure I need to put some magic value in the “Input text fields” style. There is no max-width in the default value for this style but I tried adding max-width:600px That’s had no effect. None of the other styles look like they could affect a text field. How do I do it?
