Diagnoses

Here is how rule engines diagnose the text contrast improvable issue for HTML element 630 of the Mozilla Foundation page.

Expected color contrast ratio for small font size at least 7:1, but got ratio: 5.37:1, <code>background-color: #d70022</code>, <code>foreground-color: #ffffff</code>, <code>font-size: 12pt</code> (original: <code>16px</code>), <code>font-weight: 400</code>. <small>Note:</small> The element is possibly visually hidden and that state might be temporary. For example the lazy loading technique can be used and the element will be visible at some point.
