Font Weight

Usage

Control the font weight of an element using the font-{weight} utilities.

Responsive

To control the font weight of an element at a specific breakpoint, add a {screen}: prefix to any existing font weight utility. For example, use md:font-bold to apply the font-bold utility at only medium screen sizes and above.

<p class="font-normal md:font-bold ...">The quick brown fox jumps over the lazy dog.</p>

Customizing

Font Weights

By default, Tailwind provides 10 font-weight utilities. You change, add, or remove these by editing the theme.fontWeight section of your Tailwind config.

  // tailwind.config.js
  module.exports = {
    theme: {
      fontWeight: {
-       hairline: 100,
+       'extra-light': 100,
-       thin: 200,
        light: 300,
        normal: 400,
        medium: 500,
-       semibold: 600,
        bold: 700,
-       extrabold: 800,
+       'extra-bold': 800,
        black: 900,
      }
    }
  }

Variants

默認情況下, 只有 響應式 的 font weight 變化模式 (variants) 會產生。

在 tailwind.config.js 的 variants 區塊中變更 fontWeight 屬性來決定有哪些變化模式會生成。

舉個例子來說，這個設定將會生成 響應式 和 hover 的變化模式。

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       fontWeight: ['responsive', 'hover'],
      }
    }
  }

Disabling

如果你不打算在專案中使用 font weight 功能，可以在你的設定檔裡的 corePlugins 屬性中將 fontWeight 設定為 false 來停用功能：

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     fontWeight: false,
    }
  }
