Hello,
Not a coding issue. Coding is great!
However, I was looking ahead at one of the external resources for section 7 of the HTML & CSS course, and the Bootstrap 3 Grid Intro site is not loading.

Maybe I am the only one with this issue though, as I didn't see anything mentioned about it previously.
Anywho, thought I would mention it :
Thanks for all you do~! You guys are the best!
