Bootstrap

Yes for using BootStrap from a CDN you should have internet connection!

If you save your code here in SL you could use those files offline(They are cached).

Umar Bashir If you downloaded BootStrap for using it offline you can put it inside a link tag like this <link type="text/css" rel="stylesheet" href="location_of_your_bootstraps_file_in_your_computer">

You should download bootstrap and use it offline until your site is ready to upload. When its ready to upload change it to CDN
