響應式佈局感受很高大上,很難,但實際上只用CSS也能實現響應式佈局
要用的就是CSS中的沒接查詢,下面就介紹一下怎麼運用:css
@media 類型 and (條件1) and (條件二){ css樣式 } @media screen and (max-width:1024px) { body{ background-color: red; } }
@import url("css/moxie.css") all and (max-width:980px);html
<link rel="stylesheet" type="text/css" href="css/moxie.css" media=「all and (max-width=980px)」/>佈局
下面是一個簡單的響應式的佈局HTMl代碼:url
<!doctype html> <html> <head> <meta charset="utf-8"/> <title>響應式</title> <link rel="stylesheet" type="text/css" href="index.css"/> <link rel="stylesheet" type="text/css" href="index01.css" media="screen and (max-width:1024px) and (min-width:720px)"/> <link rel="stylesheet" type="text/css" href="index02.css" media="screen and (max-width:720px)"/> </head> <body> <div class="header">頭部</div> <div class="main clearfix"> <div class="left">左邊</div> <div class="center">中間</div> <div class="right">右邊</div> </div> <div class="footer">底部</div> </body> </html>
下面是CSS樣式:spa
*{ margin:0; padding:0; text-align:center; color:yellow; } .header{ width:100%; height:100px; background:#ccc; line-height:100px; } .main{ background:green; width:100%; } .clearfix:after{ display:block; height:0; content:""; visibility:hidden; clear:both; } .left,.center,.right{ float:left; } .left{ width:20%; background:#112993; height:300px; font-size:50px; line-height:300px; } .center{ width:60%; background:#ff0; height:400px; color:#fff; font-size:50px; line-height:400px; } .right{ width:20%; background:#f0f; height:300px; font-size:50px; line-height:300px; } .footer{ width:100%; height:50px; background:#000; line-height:50px; }
<link rel="stylesheet" type="text/css" href="index01.css" media="screen and (max-width:1024px) and (min-width:720px)"/>樣式代碼code
.right{ float:none; width:100%; background:#f0f; clear:both; } .left{ width:30%; } .center{ width:70%; } .main{ height:800px; }
<link rel="stylesheet" type="text/css" href="index02.css" media="screen and (max-width:720px)"/>樣式代碼htm
.left,.center,.right{ float:none; width:100%; }
