Question

I have two font related questions on Windows 8 metro style app development:

1. is there a list of available font families, and are they existing in any Windows 8 devices?

2. how to set a font family as a global font?

Answer 1

You are not limited to system fonts. You can load your own font via CSS @font-face.
If you want to change font of every element use * selector in your stylesheet and set font-family to your favorite font. I don’t recommend using star selector, decide what elements should get your font.

@font-face {
  font-family: "your-font";
  src: url(/to-your/local-font.ttf);
}

* {
 font-family: your-font;
}
