"...[making] it easier for departments to build digital services that are accessible for everyone.
We want to ensure that there are no barriers that might prevent anyone from accessing a digital service. This means people who are hard of hearing or have visual, cognitive or motor impairments. But beyond that, it means all users – not just those with permanent disabilities.
You might, for example, be trying to listen to a piece of content in a noisy office. Or trying to read something on a screen which has the sun shining directly onto it. You might have a temporary impairment, such as an ear infection or a broken arm. Or you may, as you grow older, develop a permanent impairment.
Making services accessible means making them better for all of us."If you found that post useful, you'll also want to have a look at "An accessibility reading list", which has a lot of information to help you build in accessibility.
