printing - Use CSS to hide contents on print

I’m looking for an easy way to hide everything except a certain div and its contents.

<html>
  <head></head>
  <body>
    <div class="header">...</div>
    <div class="menu">...</div>
    <div class="content">...</div>
    <div class="footer">...</div>
  </body>.
</html>

So, for example, if I want to print only div.content, I would do it like this:

.header, .menu, .footer {
  display: none;
}

And if the layout is complicated, it becomes messy. Is there an easier way to do this with CSS?

@media print {
.noPrint {
    display:none;
  }
}

Now you need to apply the class noPrint to the elements you want to hide in printing.

It is good practice to use a style sheet specifically for printing, and and set it's media attribute to print.

Example:

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