require all universities to take a more inclusive approach to our digitally published information. This means making sure that information we provide digitally is accessible to most, ideally all, users 鈥 be they students, staff, prospective students, funders, employers, collaborators or the wider public. This not only helps people with disabilities, but ensures that the content is easier to navigate, read and hear for everyone.
The regulations are based on a set of standards called the . They can initially seem a rather daunting and unwelcome addition to already high workloads, but there are some very easy to implement actions that will improve all content irrespective of the platform or software you are using or any accessibility checker tools you might use:

Add descriptive headings using in-built styles (H1, H2, H3). This produces a list of headings and subheadings for screen readers. It also allows other readers to scan the page for the content they are looking for.
2. Alternative text for images
If you are using images to give information, you鈥檒l need to provide the same information to people with a visual impairment or those who use text-only browsers. Never use an image instead of text.
-
Provide alt text (alternative text) for the image. This should be a short, meaningful description of the image, and it can include links to more accessible content or other references.
-
Complex images such as charts, diagrams, maps and illustrations can have longer descriptions and links to more accessible content or other references.
-
Decorative images included for purely aesthetic reasons do not need alt text. So the 鈥淢ark as decorative鈥 box can be ticked in the alt text tab when using Microsoft Office.
There is no need to include 鈥淧icture of鈥 or 鈥淚mage of鈥 as screen readers identify images.
3. Use meaningful links
For screen readers that can scan links, it is important that the link describes where the link goes, for instance 鈥溾 instead of 鈥淯nderstanding accessibility 鈥.
-
Don鈥檛 use repeated link titles such as 鈥渃lick here鈥 or 鈥渇ind out more鈥 because that is what the screen reader will output.
-
Don鈥檛 use the full web address 鈥 eg, https://www.w3.org/TR/WCAG21 鈥 because screen readers will read out the link letter by letter.
The best way to write a link is how you would say it. This helps everyone.
4. Use tables only for data
Keep tables simple:
-
Avoid splitting, nesting or merging cells.
-
Use table headers so that screen readers can identify columns and rows, and so people can tab through your document.
-
Avoid blank cells because these can mislead screen readers into thinking the table has ended.
5. Colour and contrast
Make sure:
-
Colour is not used alone to show meaning. So, for example, don鈥檛 use green, amber and red to show a hierarchy.
-
There is sufficient contrast between text and background colour in your document.
Ways to do this:
-
Use your institution鈥檚 approved web colour palettes, if available; they should meet the standards.
-
You can look for text in your document that is hard to read or to separate from the background.
-
Use a tool to check the contrast, for example, or the .
