Changing default white background to an image

Hello

My site -greatactingperformances.com

What element (if in CSS) to I change to convert the white background on the main section of the hiero theme to a background image?

I will then test out the transparency of the image to make it fade nicely

Thanks

Hi glamptey99,

I guess you want to use a background image here instead of the white background, if so can you tell me if this is something for the full width of the container

Please add more details to your query

Thanks
