Diagnoses
- The CSS <code>position: sticky;</code> property is used in the styles for element <code><nav class="m24-navigation-refresh enable-main-nav-sticky m24-mzp-is-sticky" aria-label="Primary"></nav></code></p><p>Using fixed (also known as sticky) positions on websites (e.g. sticky headers) can be problematic for people with low vision who have their browser window zoomed in. This is especially problematic on mobile phones where, when zoomed in, the sticky header can take over much of the screen, hiding the content that the user wants to view.
