css 样式备忘录
1、使用百分比设置宽度
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>AA25.CN_一列自适应宽度</title> <style type="text/css"> <!-- #layout { border: 2px solid #A9C9E2; background-color: #E8F5FE; height: 200px; width: 80%; } --> </style> </head> <body> <div id="layout">一列自适应宽度(AA25.CN)</div> </body> </html>
2、div容器属性设置,设置容器自适应并居中。
margin:0px auto;
3、div多列百分比布局
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>二列宽度自适应——AA25.CN</title> <style type="text/css"> <!-- #left { background-color: #E8F5FE; border: 1px solid #A9C9E2; float: left; height: 300px; width: 20%; } #right { background-color: #F2FDDB; border: 1px solid #A5CF3D; float: left; height: 300px; width: 70%; } --> </style> </head> <body> <div id="left">左列——(AA25.CN)</div> <div id="right">右列——二列宽度自适应(AA25.CN)</div> </body> </html>
