bootstrap 4, cursor doesn't change when hovering over a button but does on anchors
提问by InitLipton
I'm using bootstrap 4 alpha, and it seems that the cursor on buttons has been removed for buttons but not anchor tags. example on the bootstrap site.
我正在使用 bootstrap 4 alpha，似乎按钮上的光标已被删除，而不是锚标签。引导站点上的示例。

In my application i have a form, with two buttons, one is to post to the form and the other is to redirec to another page. The input doesn't display the cursor but the anchor does. I know i can create a custom css class, but is there a reason why this has been removed or is it an issue with the current alpha version?
在我的应用程序中，我有一个带有两个按钮的表单，一个是发布到表单，另一个是重定向到另一个页面。输入不显示光标，但锚点显示。我知道我可以创建一个自定义 css 类，但是是否有原因将其删除，或者是当前 alpha 版本的问题？
<input type="submit" value="Sign In" class="btn btn-primary" />
<a role="button" href="@Url.Action("Register", "Account")" class="btn btn-secondary">Register Now</a>

I'm not sure Bootstrap v4 adds that on anchor elements either (can't check at the moment), but what I do know for sure is that browsers add the cursor by default whenever a link has the hrefattribute.
我不确定 Bootstrap v4 是否在锚元素上添加了它（目前无法检查），但我可以肯定的是，只要链接具有该href属性，浏览器就会默认添加光标。

add class="btn"
添加 class="btn"
it causes the cursor to be pointer
它导致光标成为指针
