How to include files for admin in materialize css?

Question

material design

I am learning materialize css. I'm trying to use it to make the same header in the admin panel as in https://pixinvent.com/materialize-material-design-...
from here materializecss.com/getting-started.html I download the materials and take the starting html. I insert

<div class="card-panel teal lighten-2">This is a card panel with a teal lighten-2 class</div>

css is working fine. But when I take the starting html from here https://pixinvent.com/materialize-material-design-... , then the same

<div class="card-panel teal lighten-2">This is a card panel with a teal lighten-2 class</div>

no longer sees css.
I understand that there are not all those css and js files that are connected to the second html. Where can they be downloaded from?
