How to place the email opt-in form 'over' a homepage Featured Image?

Hi,

This is beyond “support” and I am unable to take on customization requests with my time available for the plugin. That said, here’s one idea without doing too much custom code.

You should remove the overflow:hidden declaration for the header section in minimum and add enews-extended to the header right area (assuming you aren’t using it for something else).

Then you could add something like:

#header .enews-widget {
position: relative;
top: 360px;

That should get it, more or less, in position. You’ll need to work with the CSS to give it a background color, etc, but that’s a start. You’ll want to consider the responsive aspect of the theme too to see what it does and how you’ll need to modify the responsive CSS.
