播放视频时使展开的框保持打开状态

Question

我有一个图像映射，其中包含各种点，单击时会放大到框中。当您在框外单击时，放大的框将关闭回其原始点。

看到这个小提琴

不幸的是，当我使用 IFrame 嵌入视频并单击视频上的播放时，它会关闭放大的框，就像我在框外单击一样。

我相信这是因为它将焦点从.mappoint上移开，并将其带到IFrame。

我目前的系统只使用 HTML 和 CSS，但我很高兴扩展，我对 jQuery 等知之甚少。

我被正确地卡住了，我希望在播放和暂停视频时放大的框保持放大。你们知道我的问题的解决方案吗？

在尝试修复您的JSFiddle时，我从这个问题中询问了解决方案：

是否可以使用 javascript 焦点函数专注于div - 堆栈溢出

作为参考，我将介绍我在您的小提琴上尝试过的所有内容：

• 我尝试在您的 onclick="this.parentNode(x3).focus()" 上添加iframe，以便map-point按钮仍保持其焦点，因此保留其 CSS :focus选择器。
• 除了上述内容外，我尝试根据上面链接中投票最高的答案将tabindex="0"添加到您的map-point按钮中。不幸的是，iframe焦点压倒了tabindex。
• 我尝试使用下一个最高投票答案中的document.getElementById('bad-map-point').scrollIntoView()，但没有成功。
• 我尝试在小提琴中使用.manualfocus类名和丑陋的 JS，但我搞砸了 CSS 而不是修复它，所以我恢复了它。

然后，我找到了一个，漂亮，整洁，有效的解决方案！

• 我在您的地图点上添加了hover选择器，它适用于 iframe！

变化：

.distribution-map .map-point:active,
.distribution-map .map-point:focus,
.distribution-map .map-point:hover { //Added :hover
  ...
}

和：

.distribution-map .map-point:active .content,
.distribution-map .map-point:focus .content,
.distribution-map .map-point:hover .content { //Added :hover
  ...
}

---

它很优雅，运行流畅，没有JavaScript！

希望这有帮助！
