So, according to bootstrap docs, I need to add the following two lines within the [font="Courier New"]<head>[/font] tag:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="assets/css/bootstrap-responsive.css" rel="stylesheet">
However, I cannot find [font="Courier New"]bootstrap-responsive.css[/font] anywhere within the yiibooster directory. As always, help is appreciated.
