For Laravel 4 & 5:
<link rel="stylesheet" href="https://stackoverflow.com/questions/15232600/{{ URL::asset("assets/css/bootstrap.min.css') }}">
URL::asset
will link to your project/public/
folder, so chuck your scripts in there.
Note: For this, you need to use the “Blade templating engine“. Blade files use the .blade.php
extension.
