To fix this warning, you need to shorten your alt text for any images that have been flagged with an Image Long Alternative Text warning. Your alternative text should be 100 characters or less.
Tool Tips
Blinking is often attached to content elements using an HTML element or CSS styles in your stylesheet. A scrolling effect is typically created using the "marquee" HTML element. You can fix the error by removing these elements from your post or page content or your CSS styles.
To fix an empty table header, you need to find the correct HTML element and add text to it that describes the row or column that it applies to. To fix a missing table header, you need to find the section of code that has fewer table heading elements in it than should be present for the number of rows or columns of data, and add one or more additional elements containing text that describes the data in that row or column.
To fix a broken skip link, you will need to take a look at the intended target of the link. You must ensure that the link does exist, and is not hidden using a CSS element. It may also be possible that a skip link is flagging as broken because of a typo in the link, so be sure to check for any spelling errors in the link URL.
To fix an empty button error, you will need to find the button that is being flagged and add descriptive text to it. You will need to either: add text content within an empty button element, add a value attribute to an input that is missing one, or add alternative text to a button image.
To fix an empty heading, you will need to add content to the heading tag that has flagged the Empty Heading Tag error or remove the empty tag if it is not needed on your page.
To fix a broken ARIA reference, you will need to find the ARIA elements that are being flagged, and ensure that their reference targets are present and properly labeled. This may mean that the identifying attribute of the reference target needs to be changed to reflect the ARIA element. If the reference target is missing from the page altogether, you will need to create a reference target with the correct ID.
To fix duplicate form label errors, you'll need to determine how the field and form were created and then ensure that each field has only one label associated with it.
To fix this error, you will need to correct the longdesc attribute on your image and ensure that it links to the correct URL and does not include a link to an image file extension (such as .jpg, .png, .gif, etc.).
To fix a missing transcript error, you will need to create a transcript for any of the video or audio clips that have been flagged as missing a transcript. Once you have created the transcript, you can either add the transcript content directly within your post or page or link to the transcript if you're including it as a downloadable doc or PDF file.
To fix ambiguous anchor text, you will need to find the anchor text (or linked image alt text) that has been flagged as ambiguous and rewrite it to more clearly describe the page or document that is being linked to.
To fix incorrect heading order errors, you will need to either change the incorrect heading level to the correct heading level, or add content with the correct heading level in between the two already existing levels.
