Expanding Column Layout

Hey folks,

I am a pretty noob and still trying to understand the things, so I apologize for stupid questions. I have downloaded this template (Expanding Column Layout) and after extracting and running the index.html file in my browser, the template wont work properly. When I click on a column, it opens normally but the “X” or the “close-button” at the right top is missing, so I cannot close the column and get to the start page again like in the demo.

Obviously I have to install something additionally but I dont know what…could anyone help me?

Thx

Good evening
