Change a Page's Header Image

Question

I am using Sunrise Theme from s5themes.com , and I was wondering if in the individual pages I can have a different Header Image, because from what I can tell they use the same CSS code in displaying the header image on the Home Page.

Here is the screenshot of the Home page showing the Image as header

And here is the screenshot of the a Page (About Us) which uses the same Image (the brown texture with green part) as header only seemed zoomed-in.

I tried digging into the code and I believe this is the part in the Styles.css that deals with it.

CSS

.header-wrapper {
background: #333;
background-image: url(img/wood-only.png);
background-attachment: fixed;
background-size: cover;
min-height: 200px;

So I edited the code above, unfortunately it also affects the Image in the Home page I tried setting the background-size into

background-size: auto;

Ideally I can work with editing the template files but I am not familiar with WordPress' structure, and now I am not sure how to procede.

Answer 1

The body tag has quite a few classes eg "home page page-id-### page-template page-template-template-name" you could make use of to customize the header with css. Just specify a different target:

.home .header-wrapper {
   background-image: url(img/some-other-image.png);
}

I managed to solve this without relying too much on creating new templates, by using JetPack plugin.

And took advantage of it's ability to add Custom CSS

This is the CSS line I added

body.page .header-wrapper {
    background: #333;
    background-image: url(http://image-url/image.png);
    background-attachment: fixed;
    background-size: auto !important;
    min-height: 200px;
}
