为什么另一个客户元素的阴影根中的阴影元素的 % 宽度和高度不起作用?
Why does the % width and height for a shadow element in the shadow root of another customer element not work?
HTML:
<options-container>
<options-panel panel-type=“login”></options-panel>
</options-container>
父自定义元素样式:
options-container {
display: inline-flex;
flex-direction: column;
justify-content: flex-start;
align-items: center;
height: calc(100vh - 52px);
height: calc(100vh - (45px + 0.3vw));
min-height: max(calc(56.25vw - 52px), calc(100vh - 52px));
min-height: max(calc(56.25vw - (45px + 0.3vw)), calc(100vh - (45px + 0.3vw)));
position: fixed;
top: 52px;
top: calc(45px + 0.3vw);
right: 0;
z-index: 1;
width: calc(300px + 3vw);
-webkit-backface-visibility: hidden;
-webkit-perspective: 1000;
-webkit-transform-style: preserve-3d;

-o-transition: width 0.5s ease-in-out;
transition: width 0.5s ease-in-out;
will-change: width;
pointer-events: none;
}
子元素(在上述元素的阴影根中)样式:
:host {
display: inline-flex;
justify-content: flex-start;
align-items: center;
flex-direction: column;
width: 90%;
height: auto;
max-height: 100vh;
padding: 10px;
min-height: 10vw;
background-color: var(--white, white);
border: 2px solid var(--light-gray, lightgray);
border: 0.2vw solid var(--light-gray, lightgray);
box-sizing: border-box;
margin-top: 20px;
border-radius: 10px;
border-radius: calc(8px + 0.3vw);
overflow: hidden;
box-shadow: 0px 0px 10px 0px var(--shadow, black);
box-shadow: 0px 0px calc(8px + 0.3vw) 0px var(--shadow, black);
pointer-events: auto;
animation: fly-down 1.5s ease-out;
animation-play-state: running;
-webkit-transform: translate3d(0, 0, 0) !important;

-o-transition: max-height 0.5s ease-in-out 0.5s;
transition: max-height 0.5s ease-in-out 0.5s;
will-change: max-height;
}

在试图解释这种行为时遇到了真正的麻烦,而在试图让子元素变得可见时遇到了更多麻烦。我可能会遗漏一些非常小的东西,我不知道。但任何指导 and/or 解释将不胜感激!
已找到答案!
令人尴尬的菜鸟错误,我将影子根附加到 <options-container>
元素,这就是子元素未被渲染的原因。与 CSS 完全无关。
给自己和处于类似情况的其他人的注意事项:检查影子根。
正在做
this.shadowroot = this.attachShadow({模式: 'open'});
就是答案。
