page-break-before和page-break-after CSS属性并不会修改网页在屏幕上的显示,这两个属性是用来控制文件的打印方式。每个打印属性都可以设定4种设定值:auto、always、left和right。其中Auto是默认值,只有在有需要时,才需设定分页符号 (Page breaks)。page-break-before若设定成always,则是在遇到特定的组件时,打印机会重新开始一个新的打印页。page-break-before若设定成left,则会插入分页符号,直到指定的组件出现在一个左边的空白页上。page-break-before若设定成right,则会插入分页符号,直到指定的组件出现在一个右边的空白页上。page-break-after属性会将分页符号加在指定组件后,而非之前。在下列
程序中您将可以看到这些属性的设定:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> </head> <body> <div>This is the first div.</div> <div STYLE="page-break-before:always">This is the second div.</div> <div STYLE="page-break-after:always">This is the third div.</div> <div>This is the fourth div.</div> <div STYLE="page-break-before:right">This is the fifth div.</div> <div STYLE="page-break-after:right">This is the sixth div.</div> <div>This is the last div.</div> </body> </html>
