I downloaded the Google Font Poiret One and want to use it with Bootstrap. However, that's not been working out well so far. It looks like Comic Sans.
<link rel="stylesheet" href="fonts/PoiretOneregular.ttf">
font-family: 'Poiret One', cursive;
You are attemping to link to a
.ttf font file with a stylesheet link, which to my knowledge isn't possible.
You could always try using the CDN instead
<link href="https://fonts.googleapis.com/css?family=Poiret+One" rel="stylesheet">
If you want to use the font that you've downloaded locally, take a look at: How do I load external fonts into an HTML document?
