给登录按钮加一个loading动画，练习一下css3的动画
咱也不知道咋整动图，所以就不上预览图了，，咱闲言少叙，直接上代码：
html：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>login</title> <link rel="stylesheet" href="../css/base.css"> <link rel="stylesheet" href="../css/login.css"> </head> <body> <div class="main" id="app"> <section class="card"> <ul> <li> <h3>login</h3> </li> <li> <span>name:</span> <input type="text" name="username" placeholder="username"> </li> <li> <span>pass: </span> <input type="password" name="password" placeholder="password"> </li> <li> <div class="button" :class="{active:type}" @click="type = !type"> <span v-show="type"></span> <span v-show="type"></span> <span v-show="type"></span> <span v-show="!type">login</span> </div> </li> </ul> </section> </div> </body> <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script> <script> new Vue({ el:'#app', data() { return { type:false } }, }) </script> </html>
里边引入了两个外联样式表，base.css就不说了 就是去一些margin什么的
直接上核心代码，login.css
.main { width: 100%; height: 100%; /* background-color: hsl(59, 52%, 72%); */ /* background: -moz-linear-gradient(top, #000000 0%, #ffffff 100%); */ /* background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#000000), color-stop(100%,#ffffff)); */ /* background: -webkit-linear-gradient(top, #000000 0%,#ffffff 100%); */ /* background: -o-linear-gradient(top, #000000 0%,#ffffff 100%); */ /* background: -ms-linear-gradient(top, #000000 0%,#ffffff 100%); */ background: linear-gradient(to bottom, #360909 0%, #ac7a7a 100%); display: flex; align-items: center; justify-content: center; } .card { width: 300px; height: 200px; background-color: #fff; border: 1px wheat solid; border-radius: 10px; } .card ul { display: flex; flex-flow: column nowrap; justify-content: end; text-transform: uppercase; } h3 { height: 30px; list-style: 30px; text-align: center; letter-spacing: 6px; margin: 10px 0; } li > span { display: inline-block; width: 50px; text-align: right; } li:nth-child(2), li:nth-child(3) { height: 40px; line-height: 40px; margin: 0 20px; overflow: hidden; } input { outline: none; border: 10x solid #696969; height: 26px; line-height: 26px; width: 178px; overflow-x: scroll; font-size: 16px; padding: 0 5px; } .button { float: right; margin: 20px 30px 0 0; width: 60px; height: 30px; line-height: 30px; text-transform: uppercase; background-color: black; color: #fff; border-radius: 6px; text-align: center; border: none; cursor: pointer; transition: margin 1s, background-color 1s; } div.active { margin-right: 50%; transform: translate(50%, 0); background-color: white; border: 1px solid black; position: relative; } div.active span { display: inline-block; top: 14px; position: absolute; width: 4px; height: 4px; background-color: black; border-radius: 2px; margin-left: 10px; animation: point 1s infinite 1.3s linear; } div.active span:nth-child(2) { animation: point 1s infinite 1.4s linear; left: 20px; } div.active span:nth-child(3) { animation: point 1s infinite 1.5s linear; right: 40px; } @keyframes point { 0% { top: 12px; } 25% { top: 6px; } 50% { top: 12px; } 75% { top: 18px; } 100% { top: 12px; } }
还是那句话，chrome运行没问题，其他浏览器没有做适配
总结：
1.transition:
语法：
transition: property duration timing-function delay;
property:规定设置过渡效果的 CSS 属性的名称。
duration:规定完成过渡效果需要多少秒或毫秒。
timing-function:规定速度效果的速度曲线。(linear|ease|ease-in|ease-out|ease-in-out|cubic-bezier(n,n,n,n);)
delay:定义过渡效果何时开始。
transition: margin 1s, background-color 1s;
2.animation:
animation: point 1s infinite 1.3s linear;
@keyframes point {
0% {
top: 12px;
}
25% {
top: 6px;
}
50% {
top: 12px;
}
75% {
top: 18px;
}
100% {
top: 12px;
}
}
over!
