Method for testing accessibility

This repository was tested using WAVE's web accessibility tool. This tool returns a comprehensive list of features that may limit the ability of users to access a website, especially those using assistive technology such as screen readers. We ran this tool on a version of the repository without branding customisation, covering the pages that users most frequently interact with.

Known accessibility issues, listed by page

These issues are listed by page. Pages that are publicly accessible are listed first, and those for repository administrators can be found lower down. The number in brackets following the description represents the number of instances of that issue on the page. Below is a list of all the accessibility issues known to affect Aston Data Explorer with an explanation of what they mean.

Missing alternative text:There is no alternative text given for an image included in the page. This means that those using screen readers will not be able to access this content.
Linked image missing alternative text: There is no alternative text given for an image that is linked to from this page. This means that a screen reader has no content to present to the user regarding the function of a link.
Empty link: A link does not contain any explanatory text. This means that the purpose of the link is not presented to the user, which may cause confusion for those using screen readers.
Nearby image has same alternative text: Two images near each other have the same alternative text. This means that those using screen readers will not be able to distinguish the difference between the images.
Missing form label: A form control does not have a properly associated text label. This means that the function of the form control may not be presented to those using screen readers. The lack of visible description may also make the page harder to navigate for all users.
Very low contrast: There is very low contrast between foreground and background colours. This may make reading text on this page difficult for users, particular those with low vision.
Skipped heading level: A heading level is skipped. This may cause confusion or difficulty for those using keyboard navigation or screen readers.
Redundant title text: The title attribute is the same as text or alternative text.
Empty table header: A table header contains no text. This may result in cells with missing or incorrect header information.
Link to excel spreadsheet: This page may link to a microsoft excel document. These documents may not be accessible and the need to use a separate application may cause confusion and navigation difficulties.
Layout table: Layout tables are being used to position content visually, for example, to create columns or align content neatly for sighted users. These can introduce reading and navigation order issues especially for those using screen readers.
Underlined text: Because underlines usually indicate linked text using, them to differentiate text may cause confusion.
Very small text: Text is very small. This may make reading text on this page difficult for users, particular those with low vision.
Missing fieldset: A group of check boxes or radio buttons is not enclosed in a fieldset. This may make it difficult for those using screen readers to identify the purpose of check boxes or radio buttons.
Suspicious link text: A link contains extraneous text or may not make sense out of context. This may cause confusion about the purpose of the link.
Javascript jump menu: A javascript jump menu is a select element that triggers a new web page with the onchange event handler. This may cause difficulty for users navigating the page with a keyboard as the page will change with each change in the select menu.
Device dependent event handler: Event handlers may not be accessible for both keyboard and mouse users.
