css中格子样式的实现_html/css_WEB-ITnose
期末成绩出来,CSAPP总算没有挂,能过个好年了!
好了,这次的需求是这样的:
如图,在父盒子中放入子盒子,子盒子的宽度为50%(33%、25%类似),使得呈现以上效果,看似简单,其实还是有一些繁琐的,具体的代码为
.box{ width: 400px; height: 400px; padding: 5px; background-color: #CCC; border-radius: 10px;}.block{ float: left; width: 50%; height: 50%; border: 5px solid #ccc; box-sizing: border-box; border-radius: 7%; background-color: #685473;}
使用到的小技巧有:
1.子元素使用border-box模型
2.为子元素设置浮动
3.子元素之间的间距用和父元素背景色相同颜色的border体现(因为各种盒模型的width里都不包括margin,使用margin会使得一行撑不下两个盒子)
4.父元素加上和子元素边框宽度相同的padding(如果不加,子元素间有10px灰色,但与父元素相邻的边只有5px灰色,不美观)
这个效果在制作一些格子类小游戏的时候很有用(如连连看、2048)等等
