Help: Styling comment input box

You can use the following as suggested changes to your style.css file …

Around line 579 (font size and background color):

#commentform textarea {
  background-color:#123FFF; /* a shade of blue */
  float:none;
  font-size:2em; /* edit to your preference as px, em, or percent */
  overflow:auto;
  width:98%;
}

… (add to the end of your style.css file) for the (unstyled) submit button text:

input#submit { font-size: 2em; }

Remember to make a backup!
