How to Control Content Visibility for Printing in CSS?

Printing-Specific CSS: Displaying Selected Content

In web development, you may encounter scenarios where you need to control the visibility of specific content based on whether the user is printing a page. CSS provides a solution to this through its "@media print" feature.

Browser Support

Most major browsers support "@media print," ensuring that your print styles will work on modern devices.

Hiding Non-Printable Elements

To display only selected elements when printing, we can approach it in two ways:

Direct Tagging Method:

1. Add a "printable" class to the elements you want to print.
2. Use "@media print" to hide all elements except those with the "printable" class:

@media print {
  * { display: none; }
  .printable, .printable > * { display: block; }
}

Negative Selection Method:

1. Instead of tagging printable elements, we can hide all non-printable elements:

@media print {
  body *:not(.printable *) { display: none; }
}

Handling Links and Logos

In addition to hiding non-printable elements, you may also want to display logos or letterhead information only on printed pages. This can be achieved using the following approach:

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

<div class="noPrint">
   <a href="links.html">Links</a>
</div>
<div class="onlyPrint">
   <img src="logo.png">
   <img src="letterhead.png">
</div>

This will hide elements with the "noPrint" class in print mode, while displaying elements with the "onlyPrint" class only on printed pages.
