<div class="f:sans">

Basic usage

Set the font family

Set the typeface of an element using the font-family: syntax.

Heavy boxes perform quick waltzes and jigs.

<p class="font-family:cursive">Heavy boxes perform quick waltzes and jigs.</p>

In practice, you wouldn't arbitrarily set the font family within the template; instead, you would unify your fonts through custom variables.

Apply fonts globally

Relying on the font-family inherited behavior, you can set the entire page font in <body>.

<body class="font:sans">…</body>

Resolve whitespaces in the value

Whitespace is used in the class attribute of the template to separate different classes. To replace whitespaces with non-breaking spaces \00a0.

<p class="font-family:'Open\00a0Sans'">…</p>

Is it not very kind to use \00a0 in markup?

Predefine your font variables without \00a0.

/** @type {import('@master/css').Config} */
export default {
    variables: {
        'font-family': {
           'open-sans': 'Open Sans'
        }
    }
}

Apply your custom fonts:

<p class="font:open-sans">…</p>

Conditionally apply

Apply styles based on different states using selectors and applying conditionally.

<div class="font:mono:hover font:mono@sm font:mono@dark font:mono@print">…</div>

Apply fonts to specified elements

Use the _:where(code,pre) to select specified elements and apply the font.

<body class="font:mono_:where(code,pre)">…</body>
