Too small fonts

I've created a form at http://www.mandalaofthesun.org/mots/?page_id=97 and it works great. Only issue is the font size in the "Enter the text for your report below (copy and paste)" area and the "Please add any private message to the admins here" area. Input area fonts in all other part of the form are a good size. Just can't get these two to be the same.

I'm using the Headway theme and this is the code in the visual editor

.block-type-header span.banner a {

}

body.layout-using-single-page-50 .block-type-widget-area li.widget {

}

.block-type-gravity-forms .block-title {

}

.block-type-gravity-forms .block-title {

}

.block-type-gravity-forms .block-subtitle {

}
body .gform_wrapper input[type="text"], body .gform_wrapper input[type="email"], body .gform_wrapper input[type="tel"], body
.gform_wrapper input[type="body"], body
.gform_wrapper input[type="paragraph"] {
font-size: 14px;
color: #000;
}

Wish I knew what it all means!
Anyway, thanks for a little help.

David, thanks for your reply. Sorry to say the problem persists. For example, if I type text in the field "Give your report a title here" and then type text in "Enter the text for your report below" I see the the font sizes are quite different. I am reviewing in Firefox and Chrome.

You're the man! Thanks David. In Headway I put the code into the Live CSS editor. Looks great. Many thanks.
