我想知道当我将鼠标悬停在按钮的边缘时如何让所有的栏都变成黑色。目前，当我将鼠标悬停在中间的栏上时，我只能让一个栏变黑，但我无法弄清楚如何在鼠标悬停在实际按钮上时让所有的栏都变黑。
这是 jsfiddle:https://jsfiddle.net/nc0L83am/
代码如下:
<html>
<head>
<link rel="stylesheet" media="all" type="text/css" href="drop.css">
<style>
.c-hamburger {
display: block;
position: relative;
overflow: hidden;
margin: 0;
padding: 0;
width: 64px;
height: 64px;
font-size: 0;
text-indent: -9999px;
appearance: none;
box-shadow: none;
border-radius: none;
border: none;
cursor: pointer;
transition: background 0.1s;
border-radius:10px;
background: blue;
}
.c-hamburger:focus {
outline: none;
}
.c-hamburger span:hover{background: black;}
.c-hamburger span {
display: block;
position: absolute;
top: 28px;
left: 10px;
right: 10px;
height: 8px;
background: #e6e6e6;
border-radius:100px;
}
.c-hamburger span::before,
.c-hamburger span::after {
position: absolute;
display: block;
left: 0;
width: 100%;
height: 8px;
background-color: #e6e6e6;
content: "";
border-radius:100px;
}
.c-hamburger span::before {
top: -15px;
}
.c-hamburger span::after {
bottom: -15px;
}
.c-hamburger--htx {
}
.c-hamburger--htx span {
transition: background 0s 0.1s;
}
.c-hamburger--htx span::before,
.c-hamburger--htx span::after {
transition-duration: 0.1s, 0.1s;
transition-delay: 0.1s, 0s;
}
.c-hamburger--htx span::before {
transition-property: top, transform;
}
.c-hamburger--htx span::after {
transition-property: bottom, transform;
}
/* active state, i.e. menu open */
.c-hamburger--htx.is-active {
background-color: #cb0032;
}
.c-hamburger--htx.is-active span {
background: none;
}
.c-hamburger--htx.is-active span::before {
top: 0;
transform: rotate(45deg);
background: white;
}
.c-hamburger--htx.is-active span::after {
bottom: 0;
transform: rotate(-45deg);
background: white;
}
.c-hamburger--htx.is-active span::before,
.c-hamburger--htx.is-active span::after {
transition-delay: 0s, 0.1s;
}
</style>
</head>
<body>
<button class="c-hamburger c-hamburger--htx">
<span>toggle menu</span>
</button>
<script>
(function() {
"use strict";
var toggles = document.querySelectorAll(".c-hamburger");
for (var i = toggles.length - 1; i >= 0; i--) {
var toggle = toggles[i];
toggleHandler(toggle);
};
function toggleHandler(toggle) {
toggle.addEventListener( "click", function(e) {
e.preventDefault();
(this.classList.contains("is-active") === true) ? this.classList.remove("is-active") : this.classList.add("is-active");
});
}
})();
</script>
</body>
最佳答案
将悬停移动到按钮而不是跨度
.c-hamburger:hover span,
.c-hamburger:hover span::before,
.c-hamburger:hover span::after {
background: black;
}
