What is the method to adjust the time of print's font size?

When trying to print a datatable using the following JavaScript code:

<script type="text/javascript">
  function data(divName) {
     var printContents = document.getElementById(divName).innerHTML;
     var originalContents = document.body.innerHTML;

     document.body.innerHTML = printContents;

     window.print();

     document.body.innerHTML = originalContents;
}
</script>

The print option is generated and the file is saved, however, due to the scroll in the datatable, it does not print complete data.

Below is the anchor tag I am using:

Answer №1

To effectively manage style changes based on different screen sizes, utilizing CSS3 media queries is highly recommended.

@media screen and (max-width: 600px){
   body{
       font-size:14px;
       font-family:"Arial";
   }
}

For more information on how to use media queries, you can refer to the MDN guide available at this link.


Media queries play a crucial role in helping browsers select the appropriate styles depending on the context. The order of style precedence is as follows:

  1. Inline styling
  2. Selectors within media queries
  3. Selectors outside of media queries

If you need to override existing styles, consider adding the specific selector within a media query with the necessary property changes. This allows browsers to prioritize the styles defined within the appropriate query.

In cases where styles are inline, using the !important declaration can be a solution. However, it is generally advised to minimize the use of the !important rule.

Answer №2

When it comes to print design, make sure to include a separate CSS file.

<link rel="stylesheet" type="text/css" href="https://www.example.com/css/print.css" media="print" />

If you want to edit the print layout using inspect element, follow these steps: Open inspect element >>> More Tools >>> click on Rendering

You will find an option to Emulate CSS media, where you can select print.

Now feel free to edit the CSS and see the changes in real time.

Note: This method has been tested in Chrome.

Thank you!
