javascript - 如何更改 reddit 的嵌入评论 iframe 的最大宽度？

Question

Reddit 提供了将他们的评论嵌入网站的代码，

例如:

<div class="reddit-embed" data-embed-media="www.redditmedia.com" data-embed-parent="false" data-embed-live="false" data-embed-uuid="24a3e666-f855-4664-8e9e-9d040fef3ca6" data-embed-created="2016-06-29T16:56:02.732Z">
  <a href="https://www.reddit.com/r/Showerthoughts/comments/2safxv/we_should_start_keeping_giraffes_a_secret_from/cno7zic">Comment</a> from discussion <a href="https://www.reddit.com/r/Showerthoughts/comments/2safxv/we_should_start_keeping_giraffes_a_secret_from/">We should start keeping giraffes a secret from young children. Imagine discovering giraffes exist when you were like 15. &quot;Woah! Check out that long necked horse!&quot;</a>.
</div>
<script async src="https://www.redditstatic.com/comment-embed.js"></script>

当您将其粘贴到 HTML 时，它会呈现包含内容的 iframe。

此 iframe 的

max-width 属性设置为 800px，如何将其更改为其他值或 none ?

Answer 1

为了覆盖您无权访问的内联样式，您需要使用 !important(这是您需要使用 !important 的极端情况，否则避免)

iframe {
  max-width: none !important
}
