原生实现响应式模态框
原生实现响应式模态框
下面采用HTML+CSS+JavaScript实现模态框,并采用Flex布局和多媒体查询实现响应式。
一、模态框HTML代码
- <!DOCTYPE html>
- <html lang="en">
- <head>
- <meta charset="UTF-8">
- <title>模态框实现</title>
- <link rel="stylesheet" href="css\modal.css" type="text/css">
- </head>
- <body>
- <button class="btn" id="showModel">模态框展示</button>
- <div id="modal" class="modal">
- <div class="modal-content">
- <header class="modal-header">
- <h4>模态框标题</h4>
- <span class="close">×</span>
- </header>
- <div class="modal-body">
- <p>HTML+CSS+JS原生实现响应式模态框演示!</p>
- </div>
- <footer class="modal-footer">
- <button id="cancel">取消</button>
- <button id="sure">确定</button>
- </footer>
- </div>
- </div>
- </body>
- </html>
二、模态框CSS代码
- h4{
- margin-left: 20px;
- }
- p{
- text-align: center;
- }
- .btn{
- width: 100px;
- height: 35px;
- border-radius: 5px;
- font-size: 16px;
- color: white;
- background-color: cornflowerblue;
- }
- .btn:hover, .btn:focus{
- background-color: #95b4ed;
- }
- .modal{
- display: none;
- width: 100%;
- height: 100%;
- position: fixed;
- left: 0;
- top: 0;
- z-index: 1000;
- background-color: rgba(0,0,0,0.5);
- }
- .modal-content{
- display: flex;
- flex-flow: column nowrap;
- justify-content: space-between;
- width: 50%;
- max-width: 700px;
- height: 40%;
- max-height: 500px;
- margin: 100px auto;
- border-radius:10px;
- background-color:#fff;
- -webkit-animation: zoom 0.6s;
- animation: zoom 0.6s;
- resize: both;
- overflow: auto;
- }
- @-webkit-keyframes zoom{
- from {-webkit-transform: scale(0)}
- to {-webkit-transform: scale(1)}
- }
- @keyframes zoom{
- from {transform: scale(0)}
- to {transform: scale(1)}
- }
- .modal-header{
- box-sizing:border-box;
- border-bottom:1px solid #ccc;
- display: flex;
- justify-content: space-between;
- align-items: center;
- }
- .close{
- color: #b7b7b7;
- font-size: 30px;
- font-weight: bold;
- margin-right: 20px;
- transition: all 0.3s;
- }
- .close:hover, .close:focus{
- color: #95b4ed;
- text-decoration: none;
- cursor: pointer;
- }
- .modal-body{
- padding: 10px;
- font-size: 16px;
- box-sizing:border-box;
- }
- .modal-footer{
- box-sizing:border-box;
- border-top:1px solid #ccc;
- display: flex;
- padding: 15px;
- justify-content: flex-end;
- align-items: center;
- }
- .modal-footer button{
- width: 60px;
- height: 35px;
- padding: 5px;
- box-sizing: border-box;
- margin-right: 10px;
- font-size: 16px;
- color: white;
- border-radius: 5px;
- background-color: cornflowerblue;
- }
- .modal-footer button:hover, .modal-footer button:focus{
- background-color: #95b4ed;
- cursor: pointer;
- }
- @media only screen and (max-width: 700px){
- .modal-content {
- width: 80%;
- }
- }
模态框的显示通过animateion动画逐渐放大显示出来;
模态框响应式布局,首先设置整个模态框为flex容器,flex项目为header、body和footer,且主轴为纵向。header和footer模块又可用flex布局,flex容器为header和footer,flex项目为内部元素,主轴为水平方向。
多媒体media查询实现当屏幕小到一定程度时,模态框大小比例可适当放大。
三、模态框JavaScript代码
- <script>
- var btn = document.getElementById('showModel');
- var close = document.getElementsByClassName('close')[0];
- var cancel = document.getElementById('cancel');
- var modal = document.getElementById('modal');
- btn.addEventListener('click', function(){
- modal.style.display = "block";
- });
- close.addEventListener('click', function(){
- modal.style.display = "none";
- });
- cancel.addEventListener('click', function(){
- modal.style.display = "none";
- });
- </script>
四、效果展示
首先点击显示模态框,全屏最大显示:
横向缩小浏览器窗口宽度时,模态框横向实现响应式显示。
纵向缩小浏览器窗口高度时,模态框纵向实现响应式显示。
