Actual Results

The images such as "Task", and "Epic" present in the main content, do not have textual descriptions. Moreover, the images are defined using the CSS background property.

As a result, these images are not available for users browsing the website with the Windows High Contrast setting turned on. Also, the purpose of the images is not understood by screen reader users.

Expected Results

The image should be visible in high contrast mode and textual description should be announced using a screen reader.

Implement the image using <img> element and provide descriptive alternate text using the "alt" attribute (e.g., alt="Task") in its source code.

Alternatively, use CSS content property (with ::before and ::after pseudo-elements) to define the image to ensure that the image becomes visible when the Windows High Contrast Mode is turned on. Specify textual description using visually hidden text. If hidden text is not possible, then use the "aria-label" attribute (e.g., aria-label="Task").

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
