尝试一下
isolation: auto;
isolation: isolate;
<section class="default-example" id="default-example">
<div class="background-container">
<div id="example-element">
<img src="/shared-assets/images/examples/firefox-logo.svg" />
<p><code>mix-blend-mode: multiply;</code></p>
</div>
</div>
</section>
.background-container {
background-color: #f4f460;
width: 250px;
}
#example-element {
border: 1px solid black;
margin: 2em;
}
#example-element * {
mix-blend-mode: multiply;
color: #8245a3;
}
该属性与 mix-blend-mode 和 z-index 结合使用时尤其有用。
