if so, my first question would be “why do you use an image? Surely easier just to use css “backround: #d4ccaa” (I think that gives the same color as your image.)
If I’m on the wrong track completely, perhaps create an image showing what you want to achieve??
But I think your page looks even better if you simply remove your background image. Then the whole footer area has the same (pale green) background. Looks very good!
