Browsers and devices

Supported browsersLink to this section: Supported browsers

OUDS Web supports the latest, stable releases of all major browsers and platforms.

Alternative browsers which use the latest version of WebKit, Blink, or Gecko, whether directly or via the platform’s web view API, are not explicitly supported. However, OUDS Web should (in most cases) display and function correctly in these browsers as well. More specific support information is provided below. We mainly support baseline 2023 apart some few features that are not widely supported. See Browserslist update PR for more details.

You can find our supported range of browsers and their versions in our .browserslistrc file:

# https://github.com/browserslist/browserslist#readme

>= 0.5%
last 2 major versions
not dead
Chrome >= 120
Edge >= 120
Firefox >= 121
Firefox ESR
iOS >= 15.6
Safari >= 15.6
not Explorer <= 11
Samsung >= 23
not kaios <= 2.5 # fix floating label issues in Firefox (see https://github.com/postcss/autoprefixer/issues/1533)

We use Autoprefixer to handle intended browser support via CSS prefixes, which uses Browserslist to manage these browser versions. Consult their documentation for how to integrate these tools into your projects.

Mobile devicesLink to this section: Mobile devices

Generally speaking, OUDS Web supports the latest versions of each major platform’s default browsers. Note that proxy browsers (such as Opera Mini, Opera Mobile’s Turbo mode, UC Browser Mini, Amazon Silk) are not supported.

Desktop browsersLink to this section: Desktop browsers

Similarly, the latest versions of most desktop browsers are supported.

For Firefox, in addition to the latest normal stable release, we also support the latest Extended Support Release (ESR) version of Firefox.

Unofficially, OUDS Web should look and behave well enough in Chromium and Chrome for Linux, and Firefox for Linux, though they are not officially supported.

Internet ExplorerLink to this section: Internet Explorer

Internet Explorer is not supported.

Browser zoomingLink to this section: Browser zooming

Page zooming inevitably presents rendering artifacts in some components, both in OUDS Web and the rest of the web. Depending on the issue, we may be able to fix it (search first and then open an issue if need be). However, we tend to ignore these as they often have no direct solution other than hacky workarounds.

ValidatorsLink to this section: Validators

In order to provide the best possible experience, OUDS Web uses CSS browser hacks in several places to target special CSS to certain browser versions in order to work around bugs in the browsers themselves. These hacks understandably cause CSS validators to complain that they are invalid. In a couple places, we also use bleeding-edge CSS features that aren’t yet fully standardized, but these are used purely for progressive enhancement.

These validation warnings don’t matter in practice since the non-hacky portion of our CSS does fully validate and the hacky portions don’t interfere with the proper functioning of the non-hacky portion, hence why we deliberately ignore these particular warnings.

Our HTML docs likewise have some trivial and inconsequential HTML validation warnings due to our inclusion of a workaround for a certain Firefox bug.
