html自适应

如果只是用px来改变字体大小不可能的，可以通过rem来控制字体的大小，但是得先写好适配。各种手机适配如下

@media screen and (min-width:321px) and (max-width:375px){html{font-size:10px}}
@media screen and (min-width:376px) and (max-width:414px){html{font-size:10px}}
@media screen and (min-width:415px) and (max-width:639px){html{font-size:12px}}
@media screen and (min-width:640px) and (max-width:719px){html{font-size:12px}}
@media screen and (min-width:720px){html{font-size:16px}}
@media screen and (min-width:750px) and (max-width:799px){html{font-size:23.5px}}
@media screen and (min-width:800px)and (max-width:1199px){html{font-size:25px}}
@media screen and (min-width:1200px){html{font-size:30px}}
div.box{
	font-size: 2rem;
	height: 10rem;
	background: black;
	color: white;
	padding: 1rem;
}

例子如下
