Goal
- Allow content to be printed in a form that is appropriate to the medium.
Implementation
Provide a specific style sheet for the media type print, for example in the form: link rel="stylesheet" type="text/css" href="print.css" media="print" />.
Printing styles can correct a global style sheet (style sheet for all media or without mention of the media) or apply only for media print if the display style sheet is called by specifying the media print.

Control
This best practice can be quickly evaluated by testing the print preview in the browser, but confirmation needs the code to be inspected to find if a print style is present for the media print, which can be:
- In the form of a tag of type <link rel="stylesheet" type="text/css" media="print" href="print.css" /> ;
- In the form of a tag of type <style media="print" type="text/css">…</style> ;
- In the form of a rule
@media print {…}in an internal or external CSS; - Or in the form of a rule
@import url("print.css")print;in an internal or external CSS.
Overview and background
The 240 Opquast rules are defined and agreed upon by an extensive community of web professionals and academics. These web quality assurance guidance rules started as a list of best practices 20 years ago. They have since been revised every five years and have been tried and tested via millions of web interactions by Opquast community’s customers, including the leading CMS communities which have developed plugins for WordPress, Drupal and Prestashop. The most recent version, v4, was established in 2020.
Each rule has individual technical sheets and the rules can be searched by project phase or various topics: e-commerce, data-privacy, internationalization, security, code, etc, or by themes: accessibility, SEO, mobile, privacy, and ecodesign. The complete checklist is available on a creative commons license BY-SA.
