Php phantomjs, avoid page breaks

Question

I am using PHP-phantomjs and following the document. I can output pdf and img. http://jonnnnyw.imtqy.com/php-phantomjs/

but I have a page break problem. when the diagrams are at the end of the page but are full, they will be divided on another page, for example, a snapshot:

I found some tips:

<div id="main" style="page-break-inside: avoid;"></div> 

But it does not work, maybe I'm wrong. And if this is a solution, then I have to write this in every html element? That sounds good.

Answer 1

Here I found some solutions on github . As far as I understand, PhantomJS has an error that scales the page. Try adding to the body:

 body { zoom : 0.75 }
