我需要元素("block1"
)停留在悬停状态。
我读到,使用javascript可能是可行的。但是我无法使其正常工作。
这是我的代码。
#block1 {
display: block;
width: 60px;
height: 200px;
background-color: #fff;
margin: 0 auto;
-webkit-transition: 2s;
/* For Safari 3.1 to 6.0 */
transition: 2s;
}
#block1:hover {
height: 800px;
}
body {
font: 20px/1.1em arial, sans-serif;
background: lightgray;
}
#container1 {
margin: 0 auto;
width: 600px;
height: 1000px;
background-color: #f0dcbe;
z-index: 0;
position: relative;
}
#container2 {
position: absolute;
width: 400px;
height: 800px;
top: 100px;
left: 100px;
z-index: 2;
}
#block2 {
position: absolute;
width: 400px;
height: 60px;
background-color: #c80000;
bottom: 60px;
}
#line1 {
position: absolute;
border: 1px solid #000;
width: 400px;
height: 1px;
margin: 0 auto;
bottom: 270px;
transform: rotate(-10deg);
transform-origin: 20% 40%;
}
<div id="container1">
<div id="container2">
<div id="block1"></div>
<div id="block2"></div>
<div id="line1"></div>
<div id="line2"></div>
</div>
</div>

您可以在鼠标悬停到block1上添加事件侦听器,并为block1设置固定的高度(在您的情况下为800px)。
var block1 = document.getElementById('block1');
block1.addEventListener('mouseover', animateBox);
function animateBox(){
block1.style.height = '800px';
}

好吧,如果您想将其重叠在红色块上,可以使用z-index
。
尝试一下
body{
font:20px/1.1em arial, sans-serif;
background:lightgray;
}
#container1{
margin: 0 auto;
width: 600px;
height: 1000px;
background-color: #f0dcbe;
z-index: 0;
position: relative;
}
#container2 {
position: absolute;
width: 400px;
height: 800px;
top: 100px;
left: 100px;
z-index:2;
}
#block1 {
display: block;
width: 60px;
height: 200px;
background-color: #fff;
margin: 0 auto;
-webkit-transition: 2s; /* For Safari 3.1 to 6.0 */
transition: 2s;
z-index:1;
}
#block1:hover {
height: 800px;
}
#block2 {
position: absolute;
width: 400px;
height: 60px;
background-color: #c80000;
bottom:60px;
z-index:-1;
}
#line1 {
position:absolute;
border: 1px solid #000;
width: 400px;
height: 1px;
margin: 0 auto;
bottom: 270px;
transform: rotate(-10deg);
transform-origin: 20% 40%;
}

如果您希望白色块在悬停后仍保持扩展状态(我从注释中收集),那么这是纯CSS中的一个技巧,它非常接近。
#block1 {
display: block;
width: 60px;
height: 200px;
background-color: #fff;
margin: 0 auto;
-webkit-transition: 2s; /* For Safari 3.1 to 6.0 */
transition: 2147483s; /* very slow transition */
}
#block1:hover {
height: 800px;
transition: 2s;
}
body {
font: 20px/1.1em arial, sans-serif;
background: lightgray;
}
#container1 {
margin: 0 auto;
width: 600px;
height: 1000px;
background-color: #f0dcbe;
z-index: 0;
position: relative;
}
#container2 {
position: absolute;
width: 400px;
height: 800px;
top: 100px;
left: 100px;
z-index: 2;
}
#block2 {
position: absolute;
width: 400px;
height: 60px;
background-color: #c80000;
bottom: 60px;
}
#line1 {
position: absolute;
border: 1px solid #000;
width: 400px;
height: 1px;
margin: 0 auto;
bottom: 270px;
transform: rotate(-10deg);
transform-origin: 20% 40%;
}
<div id="container1">
<div id="container2">
<div id="block1"></div>
<div id="block2"></div>
<div id="line1"></div>
<div id="line2"></div>
</div>
</div>
诀窍是将从大到小的转换速度减慢到几乎觉察不到的速度(2147483648毫秒,或三个半星期),以便看起来什么都没有发生。
它不是完美的,但是您不需要JavaScript。
让我知道这是否是你所追求的;我可能误会了您的意图。
