引用

块引用，标签在于`<blockquote>`

<blockquote cite="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/blockquote">
  <p>The <strong>HTML <code>&lt;blockquote&gt;</code> Element</strong> (or <em>HTML Block
  Quotation Element</em>) indicates that the enclosed text is an extended quotation.</p>
</blockquote>

行内引用，标签在于<q>

<p>The quote element — <code>&lt;q&gt;</code> — is <q cite="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/q">intended
for short quotations that don't require paragraph breaks.</q></p>

引文跳转，上面两种情况的看起来很方便，但是如果不配合css或js，实际上是没有跳转效果的。

但是可以用链接的方式实现：

<p>According to the <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/blockquote">
<cite>MDN blockquote page</cite></a>:
</p>

<blockquote cite="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/blockquote">
  <p>The <strong>HTML <code>&lt;blockquote&gt;</code> Element</strong> (or <em>HTML Block
  Quotation Element</em>) indicates that the enclosed text is an extended quotation.</p>
</blockquote>

<p>The quote element — <code>&lt;q&gt;</code> — is <q cite="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/q">intended
for short quotations that don't require paragraph breaks.</q> -- <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/q">
<cite>MDN q page</cite></a>.</p>
