Hi,
I’m trying to get an image in a header to occupy the full width of the browser window and to shrink/grow as needed to fill the available space. An example of the desired behavior is here:

However, on my site I can’t seem to get the right combination of parameters to get this behavior.

With my current configuration the graphic doesn’t fill the space horizontally when the browser width is big. The graphic also doesn’t shrink & grow as I resize the browser.
Can you provide me with some guidance on how to get the desired behavior?
