Please help:

• How do I add a whole page shadow as it is in this example: http://www.innobaby.ch/  See the left and right edges of the whole page.  I found instructions for preveious versions of Website X5 (https://helpcenter.websitex5.com/post/71374), but since I am using v13, I can't find the way since some things have beem remove or place elsewhere.

• Also, where do I find in the hard drive all the images and backgrounds?  I move around and sometimes I do not have internet.  I need all the images in my hard drive.

Thanks.
