Our hope for everyone who visits the ESO website (www.eso.com) is that they’re able to find all content available with ease. For this reason, we have taken the following steps to ensure that our website is widely accessible to all.


What are we doing?

To help ESO achieve our accessibility goals we’ve been using the Web Content Accessibility Guidelines (WCAG) 2.1. These guidelines explain how to make web content more accessible for people with disabilities, and user-friendly for everyone.

There are three levels of accessibility according to WCAG – A, AA and AAA. We’ve chosen Level AA as the target for the ESO website.

To meet WCAG 2.1 AA criteria, some, but not all, of the activities we do include:

  • Quarterly review all content and code on the site for accessibility using the following tools:
  • Review all content before it’s posted to the website
  • Ensure all images have the appropriate alternative (alt) text if they are not decorative
  • Respect operating system preferences to reduce motion by disabling all animations using the prefers-reduced-motion media feature
  • Allow users to pause auto-playing videos
  • Ensure fast page loading for users with low bandwidth


How are we doing?

We’ve worked hard on the ESO website and believe we’ve achieved our goal of Level AA accessibility. Websites are constantly evolving and so are guidelines. Therefore, we monitor the website regularly to maintain this, but if you do find any problems, please get in touch via email at [email protected]
