Chrome developer tools - DOM Bread Crumb

Today, I was really stumped with some CSS and setting display:none; and display: block; on the correct DOM element. depending on @media query for Mobile responsive design.  Over and over I was incorrectly setting the correct DOM Element and then for some reason or another I finally looked at the bread crumb in Chomes F12 Developer tools, which quickly help me figure out the correct element and parent that needed the CSS applied to.  I will be using this for a long time to come. +Walt Daniels is still the best mentor to push me to use Chrome Dev tools and I am thankful for his mentoring and knowledge sharing.

Maybe this will help another developer out.
