众所周知,随着移动端高速发展,对于前端开发人员来说,HTML5+CSS3的地位越发的举足轻重了。其中的响应式设计也真正的流行起来。可能此时小码哥写这篇文章来说,也已经有些晚了,但,鄙人的目的是方便自己以后翻阅的,当然,也希望能对看到该文章的人有所帮助。什么是响应式设计,什么又是媒体查询?
所谓响应式设计:就是依据不同的设备尺寸来开发前端页面,以保证页面能在所想要的设备上能正常显示。
媒体查询:就是HTML5中针对不同设备设定的一些尺寸的区间范围,依据不同的区间编写不同的代码。以适应不同的设备。
经过小码哥查阅:当今主流设备分辨率:240*320像素,320*480像素,480*800像素(居多),640*960像素(居多),480*854(9:16)像素(少),1280*720像素(多),1280*800像素,1920*1080像素以及现如今的什么2k,4k等等。
下面是小码哥,自己闲来无事做的一个三级响应式事例页面,重点是媒体查询:

媒体查询是当前非常流行的一种响应式设计方式。其核心还是要弄清楚每种设备的尺寸问题,及布局问题。
