Diagnoses

Here is how rule engines diagnose the position sticky issue for HTML element 100 of the Clean Air Task Force (CATF) page.

1. The CSS <code>position: sticky;</code> property is used in the styles for element <code><header class="header-sticky-wrap hide-on-scroll" role="banner" id="header_sticky_wrap"></header></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.
