I am trying to change the text field width, the box one comments in. Leaving the defaults produces a text field that is expandable vertically, but the horizontal width stays fixed at 246 px. This looks very small on the page, and is difficult to type into. I would like to make it around 600 px wide.
In fact this comment box's width I'm using here would be about perfect.
I went to the Styles settings and altered the Form DIV, the Left Box DIV, and the Right Box DIV, but nothing seems to change.
I'm using the theme Twenty Thirteen on a WordPress site.
