Bug ID: 29037
Summary: Accessibility: OPAC breadcrumb links don't have
sufficient contrast
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: minor
Priority: P5 - low
Component: OPAC

The OPAC breadcrumb links are on a grey background and don't have sufficient
contrast. This makes the text difficult to read and fails to meet accessibility
criteria.
WCAG 2.1 1.4.3 Contrast (Minimum) Level AA:
"The visual presentation of text and images of text has a contrast ratio of at
least 4.5:1, except for the following:
- Large Text: Large-scale text and images of large-scale text have a contrast
ratio of at least 3:1;
- Incidental: Text or images of text that are part of an inactive user
interface component, that are pure decoration, that are not visible to anyone,
or that are part of a picture that contains significant other visual content,
have no contrast requirement.
- Logotypes: Text that is part of a logo or brand name has no contrast
requirement."
(https://www.w3.org/WAI/WCAG21/quickref/?versions=2.0#contrast-minimum)
There are several free websites for checking the contrast ratio, e.g.
https://webaim.org/resources/contrastchecker/
You can also use the built-in accessibility functions in Firefox and Chrome, as
well as specialist accessibility browser extensions like WAVE
(https://wave.webaim.org/)
