Where do I find the CSS area for a form to change appearance/size of text areas?

I am working on a form with several text areas.

The text areas are too large vertically and to small horizontally. I'd like to change the initial appearance of the text areas (similar to blue rectangle on screenprint.

When editing the properties none of the changed settings for width of text area/columns seem to take effect.

Is CSS already overriding the property settings?

Is there a way of finding out what CSS is necessary to effect that change to the initial height and width?

You can use this CSS code to adjust the dimension of the text area in your form. 

.form-textarea {

width: 800px !important;

height: 100px !important;

}

hey Jan, you guys are amazing! Not only do you have an extremely well designed product, but you even help new users in a very professional way (even the not-paying-yet-customers).

I realize that my primary problem is not knowing my way around the jotform site yet and that I'm just learning to find my way around.

Thank You!
