1、实例描述:浏览网页时,难免会有网页加载慢的情况,当网页长时间未加载完毕时,可以显示一些动画效果,以避免网页长时间空白。本实例实现的是圆形加载动画,当页面加载完成时,页面中的弧形会一直在页面中转动,具体运行效果如下图所示: 代码实现: 1、实例描述:本实例实现上下跳动的圆球加载,打开页面后,如下图所示,页面中的小圆球按照排列顺序,位于偶数个小球先往下坠落,然后奇数个小球向上跳跃,奇偶数小球循环上下跳跃。 代码实现: 1、实例描述:你见没见过3D立体式的加载动画效果呢?如下图所示,使用CSS中的transform过渡属性即可实现。你可以把立方体想象成有6个平面,那么,每个平面都可以使用 1、实例描述:本实例实现的是饼状加载动画,打开页面,可看到一个蓝色的圆形上面有一层半透明的圆弧,并且圆弧形的角度逐渐增大,直至完全覆盖蓝色圆形后,半透明圆弧的角度再度从零开始增加。具体运行效果如下图所示: 1、实例描述:本实例实现的是多点加载动画,动画开始播放时,小圆点依次向上平移然后恢复原位,同时个圆点依次被染成粉色再恢复原色,并且下方展示圆点阴影,具体效果如下图所示: css 代码如下: 1、实例描述:本实例主要实现各圆圈按顺时针放大的加载动画。打开页面后,可看到页面中含有5个蓝色小圆圈,每个小圆圈按顺时针依次逐渐放大,并且圆圈的颜色有浅变深,具体效果如下图所示: 1、实例描述:本实例实现的是小圆圈轮流放大的加载动画,打开页面后,可看到三个小圆圈逐个放大后再逐渐缩小,具体运行效果下图所示: 1、实例描述:本实例实现竖条加载动画,打开页面如下图所示,页面中有五根竖条,动画播放时,以中间竖条为对称轴,两侧的动画一致,都是逐渐边长再缩短。 1、实例描述:本实例实现的是水波扩散状的加载动画,打开本实例,可看到同心圆像水波一样逐渐放大,并且圆圈颜色逐渐由深变浅,如下图所示,打开本实例可看到页面中呈现水波扩散状的加载动画。 1、实例描述:本实例实现的按逆时针顺序逐渐放大的多点加载动画,打开页面后,页面中的圆点呈圆形排列,然后各圆点按逆时针顺序依次变小,颜色变浅,最后回复原来大小和颜色。具体运行效果如下图所示。 1、实例描述:本实例实现的是形状变化的加载动画,打开本页面可看到页面中的初始形状为正方形,并且正方形上下跳动,随后便一次改变形状为三角形、菱形。五角星形以及五边形,改变形状的同时,其背景颜色也在绿色和粉色间交替显示。如下图所示: 代码实现: 1、实例描述:本实例主要实现动态前进向前的阴影进度条效果,打开页面时,可看到进度条中蓝色部分逐渐填充白色部分,同时白色阴影也逐渐向右移动。具体运行效果如下图所示: 1、实例描述:本实例实现椭圆形的进度条加载,打开本实例后,可看到页面中是一个灰色的椭圆,随着蓝色进度条填充灰色,右侧数字从0%开始增加,如下图所示,当右侧数字变为100%时,蓝色进度条将填充整个灰色部分。 要实现animation动画,在定义关键帧以后,还需要使用动画属性来执行关键帧的变化。CSS为animation动画提供的动画属性机器含义如下表所示: 代码实现: 1、实例描述:本实例实现的是彩色进度条加载,打开本实例,可看到页面分别有四个彩色进度条分别向右填充,加载动画结束后,进度条以及进度条后方的彩色小圆点停留在动画结束的位置。具体效果如下图所示: 1、实例描述:我们在上网时,时常会遇到网页加载慢等情况,这时有的人就会测试自己电脑的网速以寻找网页加载慢的原因,测试网速时,就会出现一个加载动画,本实例将实现这样的一个加载动画,打开本实例,可看到组成圆环的长条的颜色按顺时针方向逐渐有浅变深。具体效果如下图所示: 1、实例描述:本实例实现的是斑马线样式进度条,打开本实例。可看到黄色的斑纹逐渐填充圆角矩形,如下图所示,当圆角矩形被黄色斑纹完全填充时,表示网页加载完成。 1、实例描述:在进入一些游戏网站的时候,通常会先进入一个程序加载页面,等待几秒钟后才能进入程序。本实例将制作一个程序加载的页面,运行结果如下图所示:
2、技术要点:本实例主要结合使用css3中的边框属性和动画属性实现圆形加载动画。为border: border-color border-style border-width
//border-color:设置边框颜色。
//border-style:设置边框样式。
//border-width:设置边框宽度。
需要说明的是,上面三个属性值可以在一行里设置,也可单独设置,例如,单独设置边框颜色的语法为
border-color:color
当然若以上三个属性在一行里设置时,表示设置标签的四条边框的样式相同,
同样,我们可以单独设置某一条边框的样式,例如,单独设置上边框的样式,其语法为:
Border-top: border-color border-style border-width

<html lang="en">
<head>
<meta charset="UTF-8">

<style>
div {
margin:30px;

属性
属性值
含义
animation
复合属性,以下属性的综合
指定对象所应用的动画特效
animation-name
name
指定对象所应用动画的名称
animation-duration
time+单位s(秒)
指定对象动画的持续时间
animation-timing-function
linear、ease、ease-in等6个可选值
指定对象动画的过渡类型
animation-delay
time+单位s(秒)
指定对象动画的延迟时间
animation-iteration-count
number或infinite(无限循环)
指定对象动画的循环次数
animation-direction
normal(默认值,表示正常方向)或alternate(表示正向与反向交替)
指定对象动画在循环中是否反向运动
animation-play-state
running(默认值,表示运动)或paused(表示暂停)
指定对象动画的状态
animation-fill-mode
none:表示不设置动画之外的状态;
forwards:表示设置对象状态为动画结束时的状态
backwards:表示设置对象状态为动画开始时的状态
both:表示设置对象状态为动画开始或结束时的状态指定对象动画时间之外的状态
