Accessibility Issues

These are opportunities to improve the legibility of your content.

High

Background and foreground colors do not have a sufficient contrast ratio.

These are opportunities to improve the experience of reading tabular or list data using assistive technology, like a screen reader.

High

<dl>'s do not contain only properly-ordered <dt> and <dd> groups, <script>, <template> or <div> elements.

High

Lists do not contain only <li> elements and script supporting elements (<script> and <template>).

These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
