如何 - CSS/JS 模态框

了解如何使用 CSS 和 JavaScript 创建模态框。




Modal Header

Hello World!

Modals are awesome!

Modal Footer

亲自试一试 »
步骤 1) 添加 HTML:


<!-- 触发/打开模态 -->
<button id="myBtn">Open Modal</button>

<!-- 模态 -->
<div id="myModal" class="modal">

  <!-- 模态内容 -->
  <div class="modal-content">
    <span class="close">&times;</span>
    <p>Some text in the Modal..</p>


步骤 2) 添加 CSS:


/* 模态(背景) */
.modal {
  display: none; /* 默认隐藏 */
  position: fixed; /* 留在原地 */
  z-index: 1; /* Sit on top */
  left: 0;
  top: 0;
  width: 100%; /* 全屏宽度 */
  height: 100%; /* 全屏高度 */
  overflow: auto; /* 如果需要,启用滚动 */
  background-color: rgb(0,0,0); /* 后备颜色 */
  background-color: rgba(0,0,0,0.4); /* 黑色带不透明度 */

/* 模态内容/框 */
.modal-content {
  background-color: #fefefe;
  margin: 15% auto; /* 15% 从顶部和居中 */
  padding: 20px;
  border: 1px solid #888;
  width: 80%; /* 可能或多或少,取决于屏幕大小 */

/* 关闭按钮 */
.close {
  color: #aaa;
  float: right;
  font-size: 28px;
  font-weight: bold;

.close:focus {
  color: black;
  text-decoration: none;
  cursor: pointer;

步骤 3) 添加 JavaScript:


// 获取模态
var modal = document.getElementById("myModal");

// 获取打开模态的按钮
var btn = document.getElementById("myBtn");

// 获取关闭 modal 的 <span> 元素
var span = document.getElementsByClassName("close")[0];

// 当用户点击按钮时,打开模式
btn.onclick = function() {
  modal.style.display = "block";

// 当用户点击 <span>(x) 时,关闭 modal
span.onclick = function() {
  modal.style.display = "none";

// 当用户点击模态框外的任意位置时,将其关闭
window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";

为 modal-header、modal-body 和 modal-footer 添加一个类:


<!-- 模态内容 -->
<div class="modal-content">
  <div class="modal-header">
    <span class="close">&times;</span>
    <h2>Modal Header</h2>
  <div class="modal-body">
    <p>Some text in the Modal Body</p>
    <p>Some other text...</p>
  <div class="modal-footer">
    <h3>Modal Footer</h3>



/* Modal Header */
.modal-header {
  padding: 2px 16px;
  background-color: #5cb85c;
  color: white;

/* Modal Body */
.modal-body {padding: 2px 16px;}

/* Modal Footer */
.modal-footer {
  padding: 2px 16px;
  background-color: #5cb85c;
  color: white;

/* Modal Content */
.modal-content {
  position: relative;
  background-color: #fefefe;
  margin: auto;
  padding: 0;
  border: 1px solid #888;
  width: 80%;
  box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2),0 6px 20px 0 rgba(0,0,0,0.19);
  animation-name: animatetop;
  animation-duration: 0.4s

/* Add Animation */
@keyframes animatetop {
  from {top: -300px; opacity: 0}
  to {top: 0; opacity: 1}
