IE11 Ignoring @page rule?

问题

I'm trying to set the margins on a page that I am printing. In chrome, it looks great. IE not so much. I'm trying to set the margins like so:

@media print {
    @page {
        margin: -0.5cm;
        margin-left: -1.5cm;
        margin-right: -1.5cm;
    }
}

I'm referencing the css file like this in the head:

<link rel="stylesheet" href="Content/print.css" type="text/css" media="print">

I'm able to adjust the margins just fine in chrome by tweaking the margin values, but in IE11, it seems to be completely ignoring this....

What am I doing wrong?

回答1:

The @page selector does not need to be nested, since the page context is assumed:

The declarations in an @page rule are said to be in the page context.

Negative margins are user-agent specific:

Due to negative margin values (either on the page box or on elements) or absolute positioning content may end up outside the page box, but this content may be "cut" — by the user agent, the printer, or ultimately, the paper cutter.

In addition, the CSS grammar does not define the behavior of nested at-rules.

The productions are:
