这篇文章主要介绍了CSS3 实现童年的纸飞机 ,本文通过实例代码给大家介绍的非常详细，具有一定的参考借鉴价值，需要的朋友可以参考下... 19-05-05...
今天我们来折纸飞机（可以飞出去的那种哦）
基本全用css来实现，只有一小部分的js
首先看一下飞机的构造
灰色区域为可折叠区域
白色区域为机身
三角形由border画出来的再经过各种平移翻转变成上图
写之前再补充个知识点：
我们颜色的设置不用rgba，
用hsl() h: 色调 0- 360 0(或360)表示红色，120表示绿色，240表示蓝色
s ： 饱和度 0% -100%
l : 亮度 0% - 100%
先看效果才有动力：
html:
<!--童年的纸飞机-->
<div class="airplane">
<div class="front-end show-front">
<!--宽高自适应的文本框-->
<div class="text-input" contenteditable = true></div>
<div class="fly">
fly
</div>
</div>
<div class="backup-end show-backup">
<div class="left-plane">
<!--左上角折叠区域-->
<div class="left-top fold"></div>
<!--左下角折叠区域-->
<div class="left-bottom fold"></div>
<!--机身-->
<div class="wing wing1"></div>
<div class="wing wing2"></div>
</div>
<div class="right-plane">
<!--右上角折叠区域-->
<div class="right-top fold"></div>
<!--右下角折叠区域-->
<div class="right-bottom fold"></div>
<!--机身-->
<div class="wing wing3"></div>
<div class="wing wing4"></div>
</div>
</div>
</div>
