[网页设计]关于HTML,css3自适应屏幕,自适应宽度


设置了在不同分辨率下,显示的css样式:

@media screen and (min-width:1080px){    .box{ width: 1080px;}.content{width: 1040px;}    .img{height:180px;}    .img{font-size: 48px;line-height: 180px;}    .title{font-size: 46px;line-height: 100px;}    .detail{font-size: 20px;}}@media screen and (min-width: 900px) and (max-width: 1079px) {    .box{ width: 900px; }.content{width: 860px;}    .img{height:160px;}    .img{font-size: 40px;line-height: 160px;}    .title{font-size: 38px;line-height: 80px;}    .detail{font-size: 17px;}}@media screen and (min-width: 768px) and (max-width: 899px) {    .box{ width: 768px; }.content{width: 728px;}    .img{height:140px;}    .img{font-size: 32px;line-height: 140px;}    .title{font-size: 30px;line-height: 60px;}    .detail{font-size: 14px;}}@media only screen and (min-width: 480px) and (max-width: 767px){    .box{ width: 480px; }.content{width: 440px; }    .img{height:98px;}    .img{font-size: 24px;line-height: 100px;}    .title{font-size: 22px;line-height: 40px;}    .detail{font-size: 11px;}}@media only screen and (max-width: 479px) {    .box{ width: 300px; }.content{width: 300px;}    .img{height:60px;}    .img{font-size: 16px;line-height: 60px;}    .title{font-size: 14px;line-height: 20px;}    .detail{font-size: 8px;}}

要是刚好在那个宽度上,如:屏幕宽度900,刚好
