Web fonts formats

Different font formats exist:

  • Web Open Font Format (.woff)
  • TrueType/OpenType (.ttf/.otf)
  • Scalable Vector Graphics Fonts (.svg)

Currently, most browsers support these font formats, with the exception of .svg, that is only supported by Firefox. See Wikipidia article on Web fonts.

use a custom font

To use a custom font, the font file has to be stored somewhere, either locally (same folder as your site) or remotely.

locally

  • download a font from: https://fontlibrary.org/
  • save the font files (.ttf .woff) on your website folder, best in a folder dedicate to fonts
  • write the CSS @font-face rules for each of the fonts and font files

Try changing the following example with other custom font

In this case I'll use 5by7 https://fontlibrary.org/en/font/5by7 which includes 2 styles: regular and bold.

Notice how 2 font sources (files) are used under the same font name, but with different weight, so that both the regular and bold font-styles are used.

<!DOCTYPE html>
<html>
  <head>
    <style type="text/css">

      @font-face {
      font-family: "5by7";
      src: url("fonts/5by7.ttf");
      font-weight: normal;
      font-style: normal;            
      }

      @font-face {
      font-family: "5by7";
      src: url("fonts/5by7_b.ttf");
      font-weight: bold;
      font-style: normal;            
      }

      body {
      font-size: 16pt;
      font-family: "5by7"; }



    </style>
  </head>
  <body>
    <h1>This is a custom font in Bold.</h1>
    <b>Bold again</b>
    <p>Regular font-weight in a paragraph</p>
  </body>
</html>

Open-source fonts libraries

remote custom fonts

It is possible to use custom fonts, that are not stored locally, and instead "live" in a service like Google Fonts or Open Font Library.

This method is:

  • convenient
  • easier

but, on the down-side:

  • it takes more time to load the page
  • the font can be removed at any point by the service

remote custom font example

Using the font https://fontlibrary.org/en/font/barrio and following the "Use this font" instructions:

<html>
<head>
<link rel="stylesheet" media="screen" href="https://fontlibrary.org/face/barrio" type="text/css"/> 

  <style type="text/css">
    
    h1 {   font-family: 'BarrioRegular';
           font-weight: normal;
           font-style: normal; 
    font-size: 3em;
    }
  </style>
</head>
<body>
  <h1>This is a remote custom font.</h1>
</body>
</html>
