https://fonts.google.com helps you to directly embed fonts into your web page without actually hosting them yourself.
If you want to use the free fonts, simply go over to the website, select the font/fonts you want to use, when you're done you'll automatically be given the link (<link rel="stylsheet" href="*****">) along with the "font-family: font name;". Then paste them in their appropriate places and you're done 😁
Hope I helped 😊
1) visit http://fonts.google.com/
2) select your font
3) copy link.
You can do it without copying the link too. The links are usually given as : https://fonts.googleapis.com/css?family=<your_font_family>
So if you know the name of font, just replace that <your_font_family> with font's name. E.g: https://fonts.googleapis.com/css?family=Raleway
