用css制作一个会动的球体

用css制作一个会动的球体,第1张

您好，可以先画一个有立体感的球体，或者直接网上找个图片，然后给这个球体添加动画，选择强调里的陀螺旋，在效果选项里将重复次数自行设定，就可以实现让球体在地上滚动的效果。同时还可借助在图片上覆盖诸如半透明灰色和半透明白色的圆形形状来实现球体高光的视觉错觉，让滚动显得更加真实。当然，如果像前面的人所说的地球自转，我没想到实现办法。不过说回来，PPT本身只是个平面软件，所以只能靠一系列平面的视觉错觉来营造一种立体感。

1、将对应的大图小图存放在同一个li标签中（鼠标悬浮到小图时，方便定位到大图）。

2、内部样式中利用"display:none"隐藏大图所在div。

3、鼠标悬浮到相应区域时，修改同li标签下大图所在div的display属性("display:block")。

小结：1、最上层的div必须定位，否则无法约束子元素。

2、li标签设置浮动时，图片会重叠，无法排成一列。浮动必须落实到图片。

3、小照片放在span标签中，变成了内联元素。需为其添加"display: block"转换为块级元素，才能设置图片外边距.

以下是代码：
