1、新建html文档。
2、书写hmtl代码。<div class="nav"> <ul> <li><a>网站首页</a></li> <li><a>关于我们</a></li> <li><a>产品中心</a></li> <li><a>成功案例</a></li> <li><a>联系我们</a></li> <li><a>在线留言</a></li> </ul></div>
3、书写css代码。<style>article,aside,details,figcaption,figure,footer,header,hgroup,main,nav,section,summary{display:block;}audio,canvas,video{display:inline-block;}audio:not([controls]){display:none;height:0;}[hidden]{display:none;}html{font-family:sans-serif;-ms-text-size-adjust:100%;-webkit-text-size-adjust:100%;}body{margin:0;}a:focus{outline:thin dotted;}a:active,a:hover{outline:0;}h1{font-size:2em;margin:0.67em 0;}abbr[title]{border-bottom:1px dotted;}b,strong{font-weight:bold;}dfn{font-style:italic;}hr{-moz-box-sizing:content-box;box-sizing:content-box;height:0;}mark{background:#ff0;color:#000;}code,kbd,pre,samp{font-family:monospace,serif;font-size:1em;}pre{white-space:pre-wrap;}q{quotes:"\201C" "\201D" "\2018" "\2019";}small{font-size:80%;}sub,sup{font-size:75%;line-height:0;position:relative;vertical-align:baseline;}sup{top:-0.5em;}sub{bottom:-0.25em;}img{border:0;}svg:not(:root){overflow:hidden;}figure{margin:0;}fieldset{border:1px solid #c0c0c0;margin:0 2px;padding:0.35em 0.625em 0.75em;}legend{border:0;padding:0;}button,input,select,textarea{font-family:inherit;font-size:100%;margin:0;}button,input{line-height:normal;}button,select{text-transform:none;}button,html input[type="button"],input[type="reset"],input[type="submit"]{-webkit-appearance:button;cursor:pointer;}button[disabled],html input[disabled]{cursor:default;}input[type="checkbox"],input[type="radio"]{box-sizing:border-box;padding:0;}input[type="search"]{-webkit-appearance:textfield;-moz-box-sizing:content-box;-webkit-box-sizing:content-box;box-sizing:content-box;}input[type="search"]::-webkit-search-cancel-button,input[type="search"]::-webkit-search-decoration{-webkit-appearance:none;}button::-moz-focus-inner,input::-moz-focus-inner{border:0;padding:0;}textarea{overflow:auto;vertical-align:top;}table{border-collapse:collapse;border-spacing:0;}body, html { font-size: 100%; padding: 0; margin: 0; }*, *:after, *:before { -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; }.clearfix:before, .clearfix:after { content: " "; display: table; }.clearfix:after { clear: both; }body { background: #f9f7f6; color: #404d5b; font-weight: 500; font-size: 1.05em; font-family: "Segoe UI", "Lucida Grande", Helvetica, Arial, "Microsoft YaHei", FreeSans, Arimo, "Droid Sans", "wenquanyi micro hei", "Hiragino Sans GB", "Hiragino Sans GB W3", "FontAwesome", sans-serif; }a { color: #2fa0ec; text-decoration: none; outline: none; }a:hover, a:focus { color: #74777b;}* {margin: 0; padding: 0;}.nav ul {background: white; border-top: 6px solid hsl(180, 40%, 60%);width: 200px; margin: 5em auto;}.nav ul li {list-style-type: none;position: relative;overflow: hidden;}.nav ul li a {font: normal 14px/28px Montserrat; color: hsl(180, 40%, 40%);display: block; padding: 10px 15px;text-decoration: none;cursor: pointer;user-select: none;position: relative;}.nav .ink {display: block; position: absolute;background: hsl(180, 40%, 80%);border-radius: 100%;transform: scale(0);}.nav .ink.animate {animation: ripple 0.65s linear;}@keyframes ripple {100% {opacity: 0; transform: scale(2.5);}}</style>
4、书写js并运用代码。<script src="js/prefixfree.min.js"></script><script src="js/jquery.min.js"></script><script>var parent, ink, d, x, y;$(".nav ul li a").click(function(e){ parent = $(this).parent(); if(parent.find(".ink").length == 0) parent.prepend("<span class='ink'></span>"); ink = parent.find(".ink"); ink.removeClass("animate"); if(!ink.height() && !ink.width()) { d = Math.max(parent.outerWidth(), parent.outerHeight()); ink.css({height: d, width: d}); } x = e.pageX - parent.offset().left - ink.width()/2; y = e.pageY - parent.offset().top - ink.height()/2; ink.css({top: y+'px', left: x+'px'}).addClass("animate");})</script>
5、代码整体结构
6、查看效果
