child page not displaying correctly

Unless you provide a link to a page demonstrating the problem, no one will be able to offer much in the way of specific help.

Here is a link to one of the subpages with the problem. https://www.klmarcom.com/portfolio/jd-rose-and-company

As you can see the logo image at the top is a broken image and the form at the bottom isn’t styled correctly by CSS as it is on the main pages.

Thanks.

I figured out my problem. On child pages any links to images or style sheets have to be absolute links and not relative. So I am guessing that it is probably good practice to use absolute links whenever working in WP.

Absolutely!
