Change width of paragraph text

I can’t look at your form right now but this question comes up periodically. There are a couple of support threads which cover this issue like this one.

The rules on that thread will likely work but something like this should also work:

input.ss-q-short {
    width: 385px;
    height: 35px;
}

textarea.ss-q-long {
    width: 685px;
    height: 35px;
}

Change the numbers to suit your application. The height rules are optional, the width rules are the ones you care about. Make sure you enable Custom CSS on the plugin settings page or your custom CSS will not have any effect.
