Question

这一次，我将包含代码（正如我之前被问到的那样）。问题是，即使这个代码完成了我所需要的（CSS模态/灯箱窗口），我也无法让它为top和translate属性设置动画。我认为这是一个定位问题，因为原始的例子没有使用容器的位置，而是使用了：before伪元素（我不喜欢它）。这段代码出了什么问题。

<!DOCTYPE html>
<html>
<head>
    <meta charset="iso-8859-1" />
    <title>Pure CSS Modal Window</title>
    <style>
        *
            {
            margin: 0px;
            padding: 0px;
            }
        .modal-container
            {
            position: fixed;
            display: none;
            top: 0px;
            left: 0px;
            right: 0px;
            bottom: 0px;
            background-color: rgba(0, 0, 0, 0.75);
            }
        .modal-content
            {
            position: absolute;
            top: -100%;
            left: 50%;
            width: 70%;
            max-width: 400px;
            max-height: 400px;
            transform: translateX(-50%);
            background-color: #fff;
            padding: 20px;
            border-radius: 10px;
            overflow-y: auto;
            transition: all 5s;
            }
        .modal-container:target
            {
            display: block;
            }
        .modal-container:target .modal-content

Answer 1

这是因为display状态从display: none更改为display: block，这意味着之前没有布局可以进行转换。

一种选择是将display: none替换为visibility: hidden，将display: block替换为visibility: visible。

工作示例：

*
    {
    margin: 0px;
    padding: 0px;
    }
.modal-container
    {
    position: fixed;
    visibility: hidden;
    top: 0px;
    left: 0px;
    right: 0px;
    bottom: 0px;
    background-color: rgba(0, 0, 0, 0.75);
    }
.modal-content
    {
    position: absolute;
    top: -100%;
    left: 50%;
    width: 70%;
    max-width: 400px;
    max-height: 400px;
    transform: translateX(-50%);
    background-color: #fff;
    padding: 20px;
    border-radius: 10px;
    overflow-y: auto;
    transition: all 5s;
    }
.modal-container:target
    {
    visibility: visible;
    }
.modal-container:target .modal-content
    {
    top: 50%;
    transform: translate(-50%, -50%);
    }

<a href="#modal1">Modal 1</a>
<a href="#modal2">Modal 2</a>
<div class="modal-container" id="modal1">
    <div class="modal-content">
        <p>This is the content of Modal 1</p>
        <p>This is the content of Modal 1</p>
        <p>This is the content of Modal 1</p>
        <p>This is the content of Modal 1</p>
        <p>This is the content of Modal 1</p>
        <p>This is the content of Modal 1</p>
        <p>This is the content of Modal 1</p>
        <p>This is the content of Modal 1</p>
        <p>This is the content of Modal 1</p>
        <a href="#modal-close">Close</a>
    </div>
</div>
<div class="modal-container" id="modal2">
    <div class="modal-content">
        <p>This is the content of Modal 2</p>
        <a href="#modal-close">Close</a>
    </div>
</div>

Answer 2

Alexander O＆＃;; Mara提供的解决方案效果很好（并且还教了我一点点），但我找到了另一个答案。我解决了它只是分开了DIV＆s。我的意思是，而不是：

<div class="container">
<div class="content">
    <p>Content here</p>
</div>
</div>

我用过：

<div class="container">
</div>
<div class="content">
    <p>Content here</p>
</div>

对于我使用的CSS：

.container:target + .content {}

而不是

.container:target .content {}

这一切都没有改变＆＃34;显示：无＆＃34;对于＆＃34;可见性：隐藏＆＃34;，正如亚历山大建议的那样，＆amp;它工作得很好。谢谢你的帮助。很高兴看到世界各地的人们担心其他问题和其他问题。试着解决它们。

干杯。马塞洛。

CSS过渡是否适用于定位元素？
