Google AMP - Mathml
使用 MathML，我们可以显示数学公式。在本章中，我们将看到一个实际示例，说明如何使用 MathML 并使用一些数学公式来显示相同的内容。
要使用 MathML，我们需要包含以下 javascript 文件 −
<script async custom-element = "amp-mathml" src = "https://cdn.ampproject.org/v0/amp-mathml-0.1.js"> </script>
MathML AMP 标签
mathML amp 标签的格式如下 −
<amp-mathml layout = "container"
data-formula = "\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]">
</amp-mathml>
请注意，data-formula 是指定公式的必需属性。
示例
让我们借助示例更好地理解此标签。

输出
Amp-mathml 标签在执行时会在 iframe 中呈现显示，如下所示 −
