如何解决在网格布局中单击时突出显示图像,然后将其放到最前面
我真的很困,希望有人能帮助我。 我使用的是网格布局(稍后将flexbox作为后备解决方案,但这应该没有什么区别),并且服务器图像必须在单击时位于前面,后面应该是弹出窗口(重叠),而后面应该是覆盖图您可以看到背景,即网格布局。
到目前为止,我已经设法在单击时打开弹出窗口和叠加层div,然后再次单击将其关闭。我看不到如何进行更改,例如z-index创建我需要的订单。 我所需要的只是当我单击它时将甜甜圈放在其他任何东西上…… 有什么想法吗?

解决方法
您尝试过fancybox吗?它是您可以使用的出色工具。 只需将data-fancybox属性添加到图像中即可
<div class="div1">div1 </div>
<div class="div2 popup">
<img src="https://cdn.pixabay.com/photo/2016/01/14/11/57/donut-1139832_960_720.png" width="100px" data-fancybox >Popup text...</span>
</div>
<div class="div3">div3 </div>
<div class="div4">div4 </div>
<div class="div5">div5 </div>
<div class="div6">div6 </div>
<div class="div7">div7 </div>
<div class="div8">div8 </div>
<div class="div9">div9 </div>

如果有人感兴趣,我已经解决了。我不知道这是否是最好的方法,但似乎可行:
