Can i add a bootstrap carousel slider in Unbounce?



I have coded in my editor a slider carousel with bootstrap.css owl.carousel.css and jquery.
Also i am using some custom css in an external file that i want to link to unbounce but there is not an easy way.

In this case i ve copied an pasted all the css from the external files into the javascript and css tab.

Now when i load the unbounce page i get a blank page.

Has anyone faced something similar?

Kind regards,
