page-break-after with IE and FF not working as expected_问答_开发者

I have read through a lot of the question asked here and other places and I am confused why page-breaks don't seem to work for me. I created a test html page that looks like this:

<html>
    <head>
        <style type="text/css">
            @media all
            {
                .page-break { }
            }

            @media print
            {
                div {page-break-after:always; }
            }
        </style>
    </head>
    <body>
        <div class="page-break">

I have nine of these divs. Simple enough right? This works just fine (it puts each div on a separate page as expected). Now for the stuff that is not working for IE and FF. My goal here is to create a simple html document that never breaks inside one of these 9 divs. If I change my div style to be page-break-inside:avoid it has absolutely no effect in IE or FF. If I try page-break-after:avoid or page-break-after:auto it doesn't seem to have any effect on the simple html document. Am I missing something. Does anyone have a solution that will work in both Explorer and FireFox?

Unfortunately, Firefox doesn't support "page-break-inside" so your best bet is to use "page-break-before: always". That is supported by IE and Firefox and will ensure each DIV has a full page of space to use. I would also not apply the class to the first DIV, as that would force an unnecessary break. Here is the markup:

<html>
    <head>
        <style type="text/css">
            @media print
            {
                .page-break { page-break-before: always; }
            }
        </style>
    </head>
    <body>
        <div>
            1content content content content content content content content content content content content

        </div>
        <div class="page-break">
            2content content content content content content content content content content content content 
            content content content content content content content content content content content content
        </div>
...
</body>
</html>
