我正在尝试在所有元素上方放置一个黄色圆圈,所有元素都已放置好,因此我的999999999的z索引应该放在前面,但由于某些原因它无法正常工作,有帮助吗?
.menu_maincontainer{width:100%; height:auto; display:flex; flex-direction:column; overflow:hidden; outline:1px solid red; position:relative; }
.menu_contents_container{width:100%; height:auto; background-color:red; position:relative; margin-top:300px; padding:25px;}
.menu_background_oval{width:105%; height:500px; border-radius:50%; position:absolute; left:50%; z-index:1; transform:translateX(-50%); top:-180px; background-color:red;}
.menu_contants_decorative_circle{width:200px; height:200px; border-radius:50%; border:1px solid blue; background-color:yellow; position:absolute; z-index:9999999999; left:50%; top:50px; transform:translateX(-50%); }
.menu_contents_texts_container{width:100%; min-height:500px; background-color:red; z-index:2; outline:1px solid blue; display:flex; flex-direction:column; position:relative; }
<div class="menu_maincontainer" style="">
<div class="menu_contents_container" style="">
<div class="menu_background_oval" style="">
<div class="menu_contants_decorative_circle" style=""></div>
</div>
<div class="menu_contents_texts_container" style="">
</div>
</div>
</div>
答案 0 :(得分:1)
由于menu_contants_decorative_circle
是menu_background_oval
的子元素,其z索引为1,因此圆将继承相同的z索引。您可以将其视为在特定图层上的z索引为9999999999(z索引:1),但实际上与z-index: 1;
更改圆形父级的z-index可以解决此问题:
.menu_maincontainer {
width: 100%;
height: auto;
display: flex;
flex-direction: column;
overflow: hidden;
outline: 1px solid red;
position: relative;
}
.menu_contents_container {
width: 100%;
height: auto;
background-color: red;
position: relative;
margin-top: 300px;
padding: 25px;
}
.menu_background_oval {
width: 105%;
height: 500px;
border-radius: 50%;
position: absolute;
left: 50%;
z-index: 5; /* changed */
transform: translateX(-50%);
top: -180px;
background-color: red;
}
.menu_contants_decorative_circle {
width: 200px;
height: 200px;
border-radius: 50%;
border: 1px solid blue;
background-color: yellow;
position: absolute;
z-index: 1;
left: 50%;
top: 50px;
transform: translateX(-50%);
}
.menu_contents_texts_container {
width: 100%;
min-height: 500px;
background-color: red;
z-index: 2;
outline: 1px solid blue;
display: flex;
flex-direction: column;
position: relative;
}
<div class="menu_maincontainer">
<div class="menu_contents_container">
<div class="menu_background_oval">
<div class="menu_contants_decorative_circle"></div>
</div>
<div class="menu_contents_texts_container">
</div>
