《网页布局》 |
margin 外边距 一个区域距离另外一个区域的距离 padding内边距 float:漂浮 对齐left,right clear:left,right,both 不允许left,right边有浮动元素 《 body: container=header+menu+nav+aside+cotainer+footer header=logo+banner contain=left_main+right_main+bottom_main 》 如果样式只用一次的话,则用id 多次的话就用class 网页长度最好不超过三屏 选项卡点哪个选项显示哪个,其余则隐藏 div+css模拟表格 |
