本文主要是介绍仿网易‘垃圾箱’动画效果,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
一说到动画,大家会说到CSS3动画,确实,本文带来一片简单的仿网易‘垃圾箱’动画效果,涉及到的知识点是transform、transition
transform 属性向元素应用 2D 或 3D 转换。该属性允许我们对元素进行旋转、缩放、移动或倾斜。
transform: none|transform-functions;
transition 属性是一个简写属性,用于设置四个过渡属性。
transition: property duration timing-function delay;
首先描述下预期效果:鼠标移到操纵条目,显示垃圾箱,鼠标移到垃圾箱时,垃圾箱盖自动打开。
效果很简单,但是用起来很贴心,是不是很有喜感?哈哈!
原理:对‘垃圾箱盖’,在hover时,利用transform属性顺时针旋转25度,同时利用transition应用在transform属性上即可实现动画!
