It looks like you removed the background color and border from your css. This is how it originally looks – http://demo.appfinite.com/ally/contact/. If you look around line 87 in your css you’ll see this –
blockquote,
input,
select,
textarea,
.author-box,
.breadcrumb,
.sticky,
.taxonomy-description,
.wp-caption {
background-color: #ffffff;
border: 1px solid #ffffff;
}
….it originally had this code –
background-color: #f2f2f2;
border: 1px solid #ddd;
Since you changed them both to #fff (white) they can’t be seen.
I’m guessing you were trying to edit a different part of your site. So if you need to keep the code as it is, you can always style the Gravity forms input separately by adding something like this to your css –
.gform_wrapper input {
border: 1px solid #ddd !important;
}
Let me know if that works
