Top 10 accessibility mistakes

Top 10 accessibility mistakes

When Tim Berners-Lee invented the world wide web, he intended it to be an open platform for society to connect, improve communication and build knowledge. It was a way to provide everyone with vast amounts of information, not just some or a select privileged few. It is said that building accessibility was his vision for bettering the globe.

If you want to stay in Tim's good books, you might want to avoid these incredibly common accessibility mistakes: 

1. Alt text for images

Images are often not properly marked up with alternative text for those who can't see images, or separated so that only the relevant images are relayed to the user, or conveyed. 

2. Keyboard Accessibility

Users can find themselves 'trapped' inside of a page's content and be prevented from interacting unless they're using a mouse. 

3. Dynamic Content Focus

Content appears based on a users action without any indication to those who can't see it. This could be form errors or a date picker: Equally frustrating for those who can see it but can't use it. 

4. Focus indicators

No knowledge of where a user is on the page when they're only using a keyboard. Making it very difficult to navigate the site. 

5. Data tables

Tables that have corresponding column and row heading associations that cannot be deciphered with ease. 

6. Poor heading structures

Undetermined list content where it's conveyed like a list but not structured like one. 

7. Colour cues

Using colour alone to convey a part of the page, for example 'For further information select the red button below'. Those with a colour deficiency are going to struggle. 

8. Multimedia

Missing captions from instructional or informative web experiences. 

9. Skip to content

Someone who is unable to use a mouse is forced to repeat their steps if there is no skip to content option. This would be extremely tedious on pages containing unchanging content such as a content heavy main navigation. 

10. Page titles

It's a small but very important element that is the very first thing users hear on a page. It indicates what the user is about to discover. Without it, users don't know what to expect.

Get accessibility right and it can even better your business. We'll tell you how in our next blog - so watch this space!
