1. how to change header background color ? (i want it black)
This color is defined in the css/template.css file in this code fragment:
- Code: Select all
 #gk-head {
   background: #f8f8f8;
   border-bottom: 1px solid #eee;
}
2. How to change content background color? (with image)
The white background is defined in the body element styling in the same file (css/template.css) :
- Code: Select all
 body { 
   background: #fff;
   color: #666;
   font-size: 17px;
   font-weight: 300;
   line-height: 1.6;
   margin: 0;
   min-height: 100%;
   padding: 0;
   word-wrap: break-word;
}
3. how to set up "Gk-form" to have 4 fields on my home form? Is it possible to add gravity forms in that place?
The form in the header is a Text Widget, so you can modify it to any form, but please remember that you will have to restyle it, because this theme supports only the visible form layout.
