Flex实战篇:http://www.ruanyifeng.com/blog/2015/07/flex-examples.html
1、色子数:1
思路:让圆点(即子元素)在横轴上居中在竖轴上居中,分别用justify-content和align-items
实现代码:
思路:竖列布局且在主轴方向采用justify-content的两端对齐布局,这样两个圆点会在左边呈现,然后采用align-items让其居中
实现代码:
思路:用到align-self属性让第二个和第三个圆点有自己的属性设置,分别在纵轴方向上居中和低端对齐
实现代码:
思路:先竖着放两行圆点,每行圆点里横着放两个圆点,所以最外层父元素设置align,里面的父元素设置justify-content
实现代码:
实现代码:
思路:跟四点的一样,先竖放三行在每行横放两个圆点
实现代码:
