Stretch div to A4 size
提问by Hwende
I have the following function which works great.
我有以下功能很好用。
<script type="text/javascript">
function printDiv(printpage)
{
var headstr = "<html><head><title></title></head><body>";
var newstr = document.all.item(printpage).innerHTML;
var oldstr = document.body.innerHTML;
document.body.innerHTML = headstr+newstr;
window.print();
document.body.innerHTML = oldstr;
return false;
}
</script>
However my div is about half of the paper size. Is there a way to make my div stretch to a full paper size when the function is called?
但是我的 div 大约是纸张大小的一半。有没有办法在调用函数时让我的 div 拉伸到完整的纸张大小？

You can set the div size by css to fit it in a A4 size paper CSS:

background-color: #FAFAFA;
font: 12pt "Tahoma";
}

box-sizing: border-box;
-moz-box-sizing: border-box;
}
.page {
width: 21cm;
min-height: 29.7cm;
padding: 2cm;
margin: 1cm auto;
border: 1px #D3D3D3 solid;
border-radius: 5px;
background: white;
box-shadow: 0 0 5px rgba(0, 0, 0, 0.1);
