按钮在 IE 中不可点击，但在现代浏览器中有效

Question

在此处的示例中，带有文本 "Description" 的 button.vertical-button__btn 在除 IE 之外的所有浏览器中都可以悬停和单击。（我在悬停上放置了一个 CSS 边框来说明这一点。您还可以通过出现的 'hand' 指针来查看按钮何时可点击。）

注意事项： 当我说它在 IE 中不可点击时，我的意思是完整的按钮文本（以黄色突出显示）不可点击。奇怪的是，button 元素的最右边缘确实按预期进行了点击和悬停。

是什么导致了这种行为，我怎样才能使 IE 中的功能与现代浏览器中的功能相同？

我只对支持IE 11和Edge感兴趣...IE 10及以下不需要支持。

编辑： 另一个奇怪的行为：如果我删除元素 div.project__image 按钮变得可点击，但我不知道为什么，我需要保留 div 元素。

Answer 1

我相信这是 z-index 的问题。如果您将 z-index: 200 添加到 vertical-button，即使在 IE 中，该按钮也是可点击的。

.project {
    -webkit-column-count: 2;
    -moz-column-count: 2;
    column-count: 2;
    padding: 20px;
    margin: 30px auto;
    width: 740px;
    height: 295px;
    box-shadow: 0px 4px 10px rgba(0,0,0,0.3);
}
.project__image, .project__text {
    position: relative;
    width: 280px;
    max-width: 408px;
    height: 210px;
    display: inline-block;
    margin: 0 auto;
}
.project__text {
    height: 200px;
    padding: 20px 8px 20px 8px;
}

.vertical-button {
    width: 1px;
    height: 20px;
    background: #000;
    position: absolute;
    right: -100px;
    top: calc(50% - 10px);
    display: flex;
    flex-direction: column;
    justify-content: center;
    opacity: 1;
    -webkit-transition: 0.8s;
    -moz-transition: 0.8s;
    -ms-transition: 0.8s;
    -o-transition: 0.8s;
    transition: 0.8s;
z-index: 200
}
.vertical-button__btn, 
.vertical-button__btn:focus, 
.vertical-button__btn:active {

    outline: none;
    outline-offset: 0;
    position: absolute;
    top: 0px;
    transform-origin: left top;
    transform: rotate(90deg) translateX(-32%);
    float: right;
    padding: 5px;
    cursor: pointer;
    cursor: hand;
}
.vertical-button__btn:hover {
    border: 1px solid red;
