我想将目标网页划分为三个垂直部分。但我没有这样做。

这是我的代码：

＆＃13;
＆＃13; 
const left = document.querySelector(".left");
const middle = document.querySelector(".middle");
const right = document.querySelector(".right");
const container = document.querySelector(".container");

left.addEventListener("mouseenter", () => {
  container.classList.add("hover-left");
});

left.addEventListener("mouseleave", () => {
  container.classList.remove("hover-left");
});

middle.addEventListener("mouseenter", () => {
  container.classList.add("hover-middle");
});

middle.addEventListener("mouseleave", () => {
  container.classList.remove("hover-middle");
});

right.addEventListener("mouseenter", () => {
  container.classList.add("hover-right");
});

right.addEventListener("mouseleave", () => {
  container.classList.remove("hover-right");
});
＆＃13;

我得到这样的输出： output of the current code

我想将 .middle 插入页面的中心部分？我哪里弄错了？过渡也相互重叠。

你可以尝试添加你的css：

..必须将中间容器向左移动33.3％（第一个容器结束的地方）

.split.middle {
 left: 33.3%
}

虽然最好的方法是使用display：flex https://css-tricks.com/snippets/css/a-guide-to-flexbox/

答案 1 :(得分：0)

您的CSS代码中有一些更改。你必须设置 middle 部分在悬停时的位置，如下所示

.split.middle {
  left: 33.333%;
}

.hover-left .middle {
  left: 70%;
}

.hover-middle .middle {
  left: 15%;
}

.hover-right .middle {
  left: 13%;
}

＆＃13;
＆＃13; 
const left = document.querySelector(".left");
const middle = document.querySelector(".middle");
const right = document.querySelector(".right");
const container = document.querySelector(".container");

left.addEventListener("mouseenter", () => {
  container.classList.add("hover-left");
});

left.addEventListener("mouseleave", () => {
  container.classList.remove("hover-left");
});

middle.addEventListener("mouseenter", () => {
  container.classList.add("hover-middle");
});

middle.addEventListener("mouseleave", () => {
  container.classList.remove("hover-middle");
});

right.addEventListener("mouseenter", () => {
  container.classList.add("hover-right");
});

right.addEventListener("mouseleave", () => {
  container.classList.remove("hover-right");
});

您可以使用Flexbox在CSS中完全执行此操作。使容器<div>成为灵活容器：

.container {
  display: flex;
}

分割<div>的弹性项目：

.split {
  flex: 15 1 0;
}

15 (flex-grow)：每个弹性项目将占用15＆＃34;份额＆＃34;额外的水平空间
1 (flex-shrink)：flex项目将均匀收缩，每个项目放弃1＆＃34;分享＆＃34;水平空间 0 (flex-basis)：每个弹性项目的基本宽度为0而不是基于其内容

为了扩大效果，让徘徊<div>贪婪：

.split:hover {
  flex-grow: 70;
}

您可以使用gradient backgrounds来避免使用extra :: before伪元素：

.split.middle {
  background:
    linear-gradient(var(--middle-bg-color), var(--middle-bg-color)),
    url('https://image.ibb.co/m56Czw/designer.jpg') center center no-repeat;
  background-size: cover;
}

这会创建一个背景图像，其渐变从一个半透明颜色渐变到相同的半透明颜色，并将其放在JPEG背景图像的顶部。

删除<div>上的所有定位代码，然后重新设置。
