在 Chrome 中正確位于父級上方的元素:

我怎樣才能讓它在 Firefox 中也能作業?如果overflow-y: auto從.container問題中洗掉不再出現,但這不是一個可行的解決方案,因為我需要可滾動的內容。
這是一個例子。您可以檢查它是否在 Chrome 中產生了所需的行為,但在 Firefox 中卻沒有:
.app {
overflow: hidden;
}
.container {
width: 260px;
max-height: 400px;
background: blue;
left: 10px;
right: 10px;
top: 10px;
position: fixed;
z-index: 500;
overflow-y: auto;
}
.wrapper {
height: 250px;
padding: 10px;
margin: 5px;
background: yellow;
top: 5px;
position: sticky;
}
.content {
height: 600px;
margin: 5px;
background: orange;
}
@keyframes fly-to-top {
10% {
top: 150px;
right: 80%;
width: 50px;
}
30% {
top: 120px;
right: 70%;
width: 45px;
}
60% {
top: 75px;
right: 40%;
width: 40px;
}
100% {
top: 10px;
right: 160px;
width: 35px;
}
}
.animated {
position: fixed;
right: unset;
top: 165px;
width: 50px;
background: red;
color: white;
animation: fly-to-top linear 2s forwards;
display: flex;
align-items: flex-start;
}
<div class="app">
<div class="container">
<div class="wrapper">
<div class="animated">
Text
</div>
</div>
<div class="content">
Lorem ipsum
</div>
</div>
</div>

您可以在 HTML 代碼的更高級別上將影片元素從其父元素(即具有 的元素overflow: hidden)中取出 - 作為容器的兄弟元素。我在下面的代碼片段中做到了這一點,還添加了一個z-index將影片元素放在容器上方的元素:
.app {
overflow: hidden;
}
.container {
width: 260px;
max-height: 400px;
background: blue;
left: 10px;
right: 10px;
top: 10px;
position: fixed;
z-index: 500;
overflow-y: auto;
}
.wrapper {
height: 250px;
padding: 10px;
margin: 5px;
background: yellow;
top: 5px;
position: sticky;
}
.content {
height: 600px;
margin: 5px;
background: orange;
}
@keyframes fly-to-top {
10% {
top: 150px;
right: 80%;
width: 50px;
}
30% {
top: 120px;
right: 70%;
width: 45px;
}
60% {
top: 75px;
right: 40%;
width: 40px;
}
100% {
top: 10px;
right: 160px;
width: 35px;
}
}
.animated {
position: fixed;
right: unset;
top: 165px;
width: 50px;
background: red;
color: white;
animation: fly-to-top linear 2s forwards;
display: flex;
align-items: flex-start;
z-index: 501;
}
<div class="app">
<div class="container">
<div class="wrapper">
</div>
<div class="content">
Lorem ipsum
</div>
</div>
<div class="animated">
Text
</div>

試試這個解決方案:
.wrapper位置設定為固定.content向下移動transform: translateY()- 在
.wrapper課堂上,我被添加了pointer-events: none;,因為如果游標在.wrapper沒有這個屬性的塊上,滑鼠滾輪不能滾動內容,只有在拖動滾動條時滾動才起作用。
.app {
overflow: hidden;
}
.container {
width: 260px;
max-height: 400px;
background: blue;
left: 10px;
right: 10px;
top: 10px;
position: fixed;
z-index: 500;
overflow-y: auto;
}
.wrapper {
display: flex;
height: 250px;
padding: 10px;
margin: 5px;
background: yellow;
/* top: 5px; */
position: fixed; /* changed */
/* calculate '.container' width - scroll-track-width(12px-17px) - '.wrapper' padding(left, right) - margin(left, right) */
width: calc(260px - 12px - 20px - 10px);
z-index: 5;
pointer-events: none; /* mouse wheel work with this property */
}
.content {
height: 600px;
margin: 5px;
background: orange;
/* calculate '.wrapper' properties to shift '.content' down */
/* height padding(top, bottom) margin-bottom */
transform: translateY(calc(250px 20px 5px));
}
