锚环绕按钮移动它的位置？
Anchor Wrapped Around Button Moves its Position?
我创建了一个网页 header，它将被其他网站页面继承。在我决定它会被继承之前，那样我只需要更新一次而不是跨页更新，主页按钮将包含 link 回到那个页面而不是根页面。现在主页应该包含 link 到根页面，这样下拉按钮（不是它的 dropdown-content 按钮）将 link 到该站点的主页。为此，我知道我必须在 <button class="dropbtn"></button>.
周围包裹一个锚点
在我这样做之后，我所有 header 项目的定位都变得歪斜了。我不确定为什么会这样，因为我认为 CSS 不会受到包含它的影响。
更新： 当前答案不适用于我的情况。在 JSFiddle 上，推荐的选项有效，但是当我在 SharePoint 上将 HTML 实现到我的网页 header 时，页面会在 parent 元素（link 之前的下拉列表）时重新加载重新加载同一页面，而不是重定向到我引用的 link。 In this fiddle，它演示了两个示例（答案中提供了一个示例，并在使用下拉内容的锚点时删除了按钮）。第一个 IT link 是适用于 SharePoint 的示例，但现在样式又全部歪斜了。 （当按钮元素存在时它也不会执行 "target="_blank"，但如果它只是锚元素，它会执行。）
这是预期的结果（减去锚点，只有样式）：
