我有一个Vue应用，可在屏幕上呈现一个按钮。我正在Bulma中使用CSS。页面加载时，按钮应该是带有白色字母的纯红色，这是应该的，因为没有“ is-outlined”类。当我单击按钮时，应该添加“ is-outlined”类，然后将按钮呈现为红色文本和白色背景上的边框。这是我单击按钮时发生的情况：
但是，一旦我单击其他按钮以将焦点从按钮上移开，css即被“渲染”，并且我得到了轮廓按钮。不管我做什么（单击屏幕，单击其他窗口或桌面），只要执行其他操作，按钮就会根据刚刚添加的类更改颜色。
如果再次单击该按钮，则该类将被删除，并且该按钮将立即更新回到红色背景上的白色文本。 （无需单击按钮即可。）
那么，当我添加一个类（没有立即结果）和删除一个类（立即响应）时，渲染的区别是什么？
已更新完整组件（对于Vue还是新手，所以可能不是最佳选择）

我找到了问题和解决方案。在我离开按钮之前，按钮一直没有更改为轮廓样式，因为按钮仍然处于“聚焦”状态，并且呈现了聚焦样式。这是在Chrome中发生的，下面是发生了什么的更好的解释：
“它不是集中于活动而是按钮，它具有：focus伪类 样式。 Chrome似乎在单击按钮时使按钮集中显示， 而其他人则没有。”

我通过将按钮转换为锚点并使用按钮样式“修复”了我的问题。链接与镶边按钮的处理方式不同。
