I use Montserrat font on my website, but it doesn\'t display on IE11 (windows 7). I put this other question some days ago: Montserrat font isn't displayed on IE 10 and 1
Use:
@import url(http://fonts.googleapis.com/css?family=Montserrat:400,700);
To call it inside your stylesheet and:
font-family: 'Montserrat', sans-serif;
To make something that font..
From google fonts: "Note: For best display in IE, make the stylesheet tag the first element in the HTML section. In IE, if the link is placed after tags, the entire page will block and not display anything until the font is loaded."
<link href='http://fonts.googleapis.com/css?family=Montserrat:400,700' rel='stylesheet' type='text/css'>
If that does not work, try this: https://developers.google.com/fonts/docs/webfont_loader#Example
This will make every browser "behave like Firefox".
