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 LSHTM Data Compass 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.
Empty heading: A heading contains no value. This may cause confusion and difficulty with navigation.
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.
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.
Device dependent event handler: Event handlers may not be accessible for both keyboard and mouse users.
Redundant link: Adjacent links go to the same location. This creates additional navigation and repetition for those using keyboard and screen readers.
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 als o make the page harder to navigate for all users.
Select missing label: A select element may not have an associated label. This means that its purpose might not be clear to 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.
Image with title: An image has a title attribute but no alternative text value. Though this should describe the image for those using screen readers, alternative text should be used in most cases.
Very small text: Text is very small. This may make reading text on this page difficult for users, particular those with low vision.
Redundant title text: The title attribute is the same as text or alternative text.
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.
Broken ARIA reference: No target is set for ARIA references, this means that the description will not be presented.
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.
Link to PDF document: This page may link to a PDF document. These documents may not be accessible and the need to use a separate application may cause confusion and navigation difficulties.
Orphaned form label: A form label exists but is not correctly associated with a form control. This may cause confusion for those using screen readers.
Tabindex: A positive tabindex value is present. These alter the natural tab order, which may cause confusion and decrease keyboard accessibility.
Redundant alternative text: Alternative text is likely insufficient or contains extraneous information. This means the content of the image may not be acessible to those using screen readers.
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.
