Supported devices

We want to give a consistent experience across browsers and devices. But, we know that small variations can be inevitable.

You should use new technology and the latest features. Apply them in a way that allows users who do not have (or intentionally disable) these features to access the same content. Understand the opportunities and the limits of the medium: design with honesty.

Supported browsers and devices as of December 2018

These statistics are based on traffic to the coop.co.uk website for the last 6 months. Always check the traffic to your service and base you support from that as well. These stats are meant as a starting point.

Levels of support

'Will test and support' means:

  • all content must be readable and usable
  • all functionality must work
  • variations to the presentation of content must be minimised
  • the CSS (where used) must be rendered by supported web browsers that present a fully-styled version of the page
  • pages should be developed to maximise the user experience for the browser that has the highest proportion of users

'Old browsers' means:

  • all core content must be readable and usable
  • navigation must work
  • any degradation to functionality must be graceful degradation
  • any degradation to presentation must not obscure content

How to test

For manual browser and device testing we have a range of devices in-house to match what we support. We also use virtual machines, our internal Co-op colleague devices and Browserstack. For more information on how to test email design@coopdigital.co.uk.

Maintenance

We’ll update this information as new versions become available and when our users' choice of browser changes.
