CSS基础测试18期 - Githubissues

zhangxinxu commented 4 years ago

实现下图所示的布局效果：

要求布局里面每个元素尺寸安装容器尺寸自适应。

请附上对应的CSS代码，注意缩进和代码高亮，可以使用下面语法进行高亮：

```html
你的代码在这里
```

```css
你的代码在这里
```

本期小测需要提供在线demo，不要参考别人的回答，诚实守信。

本期小测无直播答疑，但是会总结要点。

感谢您的参与！

要点： 3D transform translateZ轴控制，或者2D transform sacle控制都是可以的。请避免横向定位，否则会降低日后的维护性和拓展性，要把定位的变量控制在1个是最佳的。
