我正在尝试使用伪元素设置边框样式。我有一个div,这个div有一个顶部边框。当我将鼠标悬停在div上时,我希望边框有一个小箭头。我已经能够实现这一点,但是我想要的是当我将鼠标悬停在div上时,小箭头 SLIDE DOWN SLOWLY 。我试图添加一些过渡但转换似乎不适用于:: before元素。我已经查看了Stackoverflow上所有问题类似的问题,但没有一个解决方案似乎能够解决我的问题
这是代码。
HTML
<div class="flexContainer">
<div class="flexContainerBox flexContainerBox1">
<div class="flexContainerBoxBorderRight"></div>
</div>
<div class="flexContainerBox flexContainerBox2">
<div class="flexContainerBoxBorderRight"></div>
</div>
<div class="flexContainerBox flexContainerBox3">
<div class="flexContainerBoxBorderRight"></div>
</div>
<div class="flexContainerBox flexContainerBox4">
<div class="flexContainerBoxBorderRight"></div>
</div>
<div class="clear"></div>
</div>
和CSS
.flexContainer {
display: flex;
flex-direction: row;
}
.flexContainerBox {
flex: 1;
border-top: 20px solid transparent;
position: relative;
padding: 50px;
font-family: "Open Sans Bold";
}
.flexContainerBoxBorderRight {
border-right: 1px solid #ccc;
position: absolute;
top: 10%;
bottom: 10%;
right: 0;
}
.flexContainerBox1 {
border-top-color: #15AF04;
color: #15AF04
}
.flexContainerBox2 {
border-top-color:#ffd470;
color: #ffd470;
}
.flexContainerBox3 {
border-top-color: #1b63b1;
color: #1b63b1;
}
.flexContainerBox4 {
border-top-color: #dd0000;
color: #dd0000;
}
.flexContainerBox::before{
-webkit-transition: all 1.5s ease-in-out;
-moz-transition: all 1.5s ease-in-out;
-ms-transition: all 1.5s ease-in-out;
-o-transition: all 1.5s ease-in-out;
transition: all 1.5s ease-in-out;
}
.flexContainerBox:hover::before {
content: '';
position: absolute;
border: 15px solid transparent;
border-bottom: 0;
position: absolute;
left: 50%;
top: 0;
-moz-transform: translate(-50%, 100%);
-ms-transform: translate(-50%, 100%);
-webkit-transform: translate(-50%, 100%);
transform: translate(-50%, 0%);
}
.flexContainerBox1:hover::before {
border-top-color: #15AF04;
}
.flexContainerBox2:hover::before {
border-top-color: #ffd470;
}
.flexContainerBox3:hover::before {
border-top-color: #1b63b1;
}
.flexContainerBox4:hover::before {
border-top-color: #dd0000;
}
任何解决方案,即使是JQUERY或Pure JS解决方案也将受到赞赏。

问题是当容器没有悬停时,伪元素不存在:
.flexContainerBox:hover::before {
content: '';
position: absolute;
border: 15px solid transparent;
border-bottom: 0;
position: absolute;
left: 50%;
top: 0;
-moz-transform: translate(-50%, 100%);
-ms-transform: translate(-50%, 100%);
-webkit-transform: translate(-50%, 100%);
transform: translate(-50%, 0%);
}
您应该将其中一些样式移动到.flexContainerBox::before
样式(具有过渡样式的样式):
.flexContainerBox::before {
content: '';
position: absolute;
border: 15px solid transparent;
border-bottom: 0;
position: absolute;
left: 50%;
top: 0;
-webkit-transition: all 1.5s ease-in-out;
-moz-transition: all 1.5s ease-in-out;
-ms-transition: all 1.5s ease-in-out;
-o-transition: all 1.5s ease-in-out;
transition: all 1.5s ease-in-out;
}
要不对箭头的居中(translate(-50%, ...)
)设置动画,可以添加以下内容:
-moz-transform: translateX(-50%);
-ms-transform: translateX(-50%);
-webkit-transform: translateX(-50%);
transform: translateX(-50%);
另外,还有一个小错字:
transform: translate(-50%, 0%);
变为
transform: translate(-50%, 100%);

从此css hover
=&gt;中删除.flexContainerBox:hover::before
.flexContainerBox::before
,动画应该有用。
