my page is a div set and a div, wants to achieve the following effect:
is that the background only acts on the annular area and does not cover the div2.
Baidu listed below, saying that it wants to set up zMui index, but the setting still has no effect. Xiaobai, ask for advice. Thank you.
<body>
<!-- div1 -->
<div style="z-index: -100">
<!-- div2 -->
<div class="col-md-10 col-md-offset-1" style="margin: 20px 100px 20px 100px;box-shadow: 0px 0px 20px;z-index: 999"> Content </div>
</div>
</body>
