A modern, great and responsive theme

Well, I’m developing an educational website to my gighschool students. I’m using the free version of this theme and really it looks very well. I’m teacher in computing science and the modern style of this template is perfect to te purpose of my site.
The only problem I have, is that I did some tests uploading the website from my computer (localhost) to the Internet and sometimes it doesn’t load the font awesome icons of the featured boxes and the icons of the pulldowns in the main menu.
Although that, it’s a very good template and it’s pretty easy to edit some things from the source code if you want to go beyond the possibilities of the WP customizer
