href=\"https://github.com/jantimon/text-box-trim-examples#usecases\"></a><p></p>\n<p>Here are some cases where this property can be useful:</p>\n<p></p><h3>Centering text in buttons</h3><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples#centering-text-in-buttons\"></a><p></p>\n<p><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples/blob/main/docs/button.webp\"><img src=\"https://github.com/jantimon/text-box-trim-examples/raw/main/docs/button.webp\" alt=\"Button\" /></a></p>\n<p>With text-box-trim:</p>\n<div><pre><span>button</span> {\n  <span>text-box-trim</span><span>:</span> both;\n  <span>text-box-edge</span><span>:</span> cap alphabetic;\n  <span>padding</span><span>:</span> <span>10<span>px</span></span>\n}</pre></div>\n<p><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples/blob/main/docs/button-leading-trim.webp\"><img src=\"https://github.com/jantimon/text-box-trim-examples/raw/main/docs/button-leading-trim.webp\" alt=\"Button with leading trim\" /></a></p>\n<p></p><h3>Spacing Systems</h3><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples#spacing-systems\"></a><p></p>\n<p>Most design systems have a spacing system that is based on multiples of a base unit. For example, a spacing system might have a base unit of 4px, and then multiples of that unit, such as 8px, 12px, 16px, etc. This is a great way to ensure that spacing is consistent across the design system.</p>\n<p>However the added line-height destroys the spacing system:</p>\n<p><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples/blob/main/docs/spacing-system.webp\"><img src=\"https://github.com/jantimon/text-box-trim-examples/raw/main/docs/spacing-system.webp\" alt=\"Spacing systems without leading trim\" /></a></p>\n<p></p><h3>Icons</h3><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples#icons\"></a><p></p>\n<p>Aligning icons with text is a common problem. With leading trim, you can align the icon with the text:</p>\n<p><a target=\"_blank\" href=\"https://twitter.com/rauchg/status/1590375127136763907?s=46&amp;t=YizBtCVEYqCeqBbJWI6quA\"><img src=\"https://github.com/jantimon/text-box-trim-examples/raw/main/docs/icon.jpeg\" alt=\"Icon\" /></a></p>\n<p><a target=\"_blank\" href=\"https://iamvdo.me/en/blog/css-font-metrics-line-height-and-vertical-align\"><img src=\"https://github.com/jantimon/text-box-trim-examples/raw/main/docs/icon2.png\" alt=\"Icon with leading trim\" /></a></p>\n<p></p><h3>Images</h3><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples#images\"></a><p></p>\n<p>In articles images are often placed next to images. The leading trim property allows you to remove the whitespace above the text to align the text with the image.</p>\n<p><a target=\"_blank\" href=\"https://github.com/w3c/csswg-drafts/issues/3240\"><img src=\"https://github.com/jantimon/text-box-trim-examples/raw/main/docs/image.png\" alt=\"Image\" /></a></p>\n<p></p><h3>Art</h3><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples#art\"></a><p></p>\n<p>Especially in logo design and art leading trim can be used to create aligned different text elements:</p>\n<p><a target=\"_blank\" href=\"https://en.99designs.it/blog/tips/typography-design/\"><img src=\"https://github.com/jantimon/text-box-trim-examples/raw/main/docs/art.jpg\" alt=\"Art\" /></a></p>\n<p></p><h2>Open Issues</h2><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples#open-issues\"></a><p></p>\n<ul>\n<li><a target=\"_blank\" href=\"https://bugzilla.mozilla.org/show_bug.cgi?id=1816038\">Firefox Issue 1816038 - [css-inline-3] Implement <code>text-box-trim</code> (formerly <code>leading-trim</code>)</a></li>\n<li><a target=\"_blank\" href=\"https://bugs.chromium.org/p/chromium/issues/detail?id=1411581\">Chromium Issue 1411581 - Implement <code>text-box-trim</code> property</a></li>\n<li><a target=\"_blank\" href=\"https://bugs.webkit.org/show_bug.cgi?id=252161\">Webkit Issue 252161 - [leading-trim] nested elements shift text upwards</a></li>\n</ul>\n<p></p><h2>Related Links</h2><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples#related-links\"></a><p></p>\n<ul>\n<li><a target=\"_blank\" href=\"https://www.w3.org/TR/css-inline-3/#leading-trim\">w3.org text-box-trim</a></li>\n<li><a target=\"_blank\" href=\"https://www.w3.org/TR/css-inline-3/#text-box-edges\">w3.org text-box-edge</a></li>\n<li><a target=\"_blank\" href=\"https://medium.com/microsoft-design/leading-trim-the-future-of-digital-typesetting-d082d84b202\">Leading-Trim: The Future of Digital Typesetting</a></li>\n<li><a target=\"_blank\" href=\"https://en.99designs.it/blog/tips/typography-design/\">Typography design 101: a guide to rules and terms</a></li>\n<li><a target=\"_blank\" href=\"https://seek-oss.github.io/capsize/\">CapSize</a></li>\n<li><a target=\"_blank\" href=\"https://iamvdo.me/en/blog/css-font-metrics-line-height-and-vertical-align\">Deep dive CSS: font metrics, line-height and vertical-align</a></li>\n<li><a target=\"_blank\" href=\"https://kekee000.github.io/fonteditor/index-en.html\">Online fonteditor</a></li>\n</ul>\n<p></p><h2>Credits</h2><a target=\"_blank\" href=\"https://github.com/jantimon/text-box-trim-examples#credits\"></a><p></p>\n<ul>\n<li><a target=\"_blank\" href=\"https://twitter.com/fantasai\">Elika J.
