Basics of Google Font API

Link to CSS files

You essentially hotlink directly to CSS files on Google.com. Through URL parameters, you specificity which fonts you want, and what variations of those fonts.

<head>
   <link rel="stylesheet" type="text/css" href="http://fonts.googleapis.com/css?family=Tangerine:bold,bolditalic|Inconsolata:italic|Droid+Sans">
</head>

CSS

In your CSS you can then specify these new fonts by name on any element you wish to use them.

body { font-family: 'Tangerine', 'Inconsolata', 'Droid Sans', serif; font-size: 48px; }

FontLoader

You can use the FontLoader JavaScript instead of linking to the CSS. It has advantages, like controlling the Flash of Unstyled Text (FOUT), and also disadvantages, like the fact that the fonts won’t load for users with JavaScript off.

<script src="http://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js"></script>
<script type="text/javascript">
  WebFont.load({
    google: {
      families: ['Cantarell']
    }
  });
</script>
<style type="text/css">
  .wf-loading h1 { visibility: hidden; }
  .wf-active h1, .wf-inactive h1 {
    visibility: visible; font-family: 'Cantarell';
  }
</style>

Those class names, e.g .wf-loading get applied to the <html> element. So notice when the fonts are “loading”, you can use that class name to hide the text. Then when they are shown, make them visible again. That is how FOUT is controlled.

    This is still new so kinda complicated for newer coders. But it will develop more and soon be very easy.

Remember:
  • Be nice.
  • Wrap multiline code in <pre> and <code> tags and escape it first (turn <'s into &lt;'s).
  • You may use regular HTML stuff like <a href="">, <em>, and <strong>
