Material UI是一款功能非常强大,界面却十分清新简洁的CSS框架,Material UI利用了Google的Material Design 全新设计语言,并且让每一个UI组件都变得非常独立,因此开发者使用Material UI也会比较简单。和Bootstrap类似,Material UI提供了很多常用的UI组件,除了最基本的菜单、按钮、滑动杆、进度条、单选框/复选框外,它还提供了一个非常有趣的日历组件,另外还提供了一些很有趣的图标。
不过,这里我并不打算介绍Material UI的使用,而是介绍如果实现Material UI内的动画特效,比如点击按钮会出现波浪扩散的动画效果、表单获取焦点动画等等。
注意:要使用下面的动画效果,必须引入jQuery。
一、点击按钮会出现波浪扩散的动画效果
为了效果,我这里特意将波浪的颜色加深。
先看效果:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <script src="js/jquery-3.1.1.js"></script> <style type="text/css"> button { outline: none; position: relative; overflow: hidden; padding: 5px 10px; background: #fff; border: 1px solid #d9d9d9; transition: all .3s; } .ripple { width: 0; height: 0; border-radius: 50%; background: rgba(0, 0, 0, .5); -webkit-transform: scale(0); transform: scale(0); position: absolute; opacity: 1; } .rippleEffect { -webkit-animation: rippleEffect 2s cubic-bezier(0.23, 1, 0.32, 1); animation: rippleEffect 2s cubic-bezier(0.23, 1, 0.32, 1); } @keyframes rippleEffect { 100% { transform: scale(2); opacity: 0; } } @-webkit-keyframes rippleEffect { 100% { -webkit-transform: scale(2); opacity: 0; } } </style> <script type="text/javascript"> $(function() { function ripple(event, $this) { event = event || window.event; var x = event.pageX || event.originalEvent.pageX; var y = event.pageY || event.originalEvent.pageY; var wx = $this.width(); x = x - $this.offset().left - wx / 2; y = y - $this.offset().top - wx / 2; var span = ‘<div class="ripple"></div>‘; $this.prepend(span); $(".ripple").css({ width: wx, height: wx, top: y + "px", left: x + "px" }).addClass("rippleEffect"); $(document).one("webkitAnimationEnd animationend", ".ripple", function() { $(".ripple").remove(); }); } $("button").on("click", function(e) { ripple(e, $(this)); }); }) </script> </head> <body> <button type="button"> 点我 </button> </body> </html>
二、表单获取焦点的动画
效果如下:
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8" /> <title>Document</title> <script src="js/jquery-3.1.1.js"></script> <meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" /> <style type="text/css"> .material-box { position: relative; width: 200px; height: 30px; } .material-box input { border: none; width: 100%; height: 30px; border-bottom: 1px solid rgb(224, 224, 224); outline: none; } .material-box hr { position: absolute; top: 100%; width: 100%; margin: 0 auto; border-top: 2px solid rgb(0, 188, 212); transform: scale(0); transition: all 450ms cubic-bezier(0.23, 1, 0.32, 1) 0ms; } </style> <script type="text/javascript"> $(function() { var inputs = document.querySelector("input"); var hr = document.querySelector("hr"); inputs.addEventListener("focus", function() { hr.style.transform = "scale(1)"; }); inputs.addEventListener("blur", function() { hr.style.transform = "scale(0)"; }); $("button").on("click", function(e) { ripple(e, $(this)); }); }) </script> </head> <body> <div class="material-box"> <input type="text" placeholder="text" /> <div> <hr/> </div> </div> </body> </html>
三、checkbox
下面用到了字体图标fontawsome
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8" /> <title>Document</title> <script src="js/jquery-3.1.1.js" type="text/javascript" charset="utf-8"></script> <style type="text/css"> .ww-checkbox { display: inline-block; position: relative; width: 20px; height: 20px; } .ww-checkbox input { opacity: 0; width: 20px; height: 20px; } .ww-checkbox-box { width: 20px; height: 20px; position: absolute; top: 0; left: 0; z-index: 0; line-height: 16px; border: 1px solid #D9D9D9; text-align: center; } .ww-checkbox-box .fa { display: none; font-size: 12px; font-weight: normal; color: #fff; } .ww-checkbox.active .ww-checkbox-box { background-color: #49be38; border: 1px solid #fff; } .ww-checkbox.active .fa { display: inline; } </style> <script type="text/javascript"> $(function() { $(".ww-checkbox").on("click", function() { if($(this).hasClass("active")) { $(this).removeClass("active"); } else { $(this).addClass("active"); } }); }) </script> </head> <body> <div class="ww-checkbox"> <div class="ww-checkbox-box"><span class="fa fa-check"></span></div> <input type="checkbox" class="ww-checkbox-input" value=""> </div> </body> </html>
