So much of accessibility is about making your content clear and understandable to a wide range of users. Structuring your content can really help here. Adding headings for each section of text particularly helps with assistive technologies like screen readers. Headers can help organize your content into groups, and show the relationships within your content.

If you have a lot of content, finding something specific can be a challenge for your users. For accessibility, this guideline was created to support people that have different ways of thinking or finding things -- but I find this useful in all sorts of contexts. Strong navigation implies structure on your site, structure that can help people find what they are after.

One of the most common issues we run into making websites accessible is contrast -- making sure the difference between the color and brightness of the text against the background is enough that it's clearly readable.

Blue text on a dark background can be very difficult to read -- but it's not just brightness. Red-green color-blindness affects around 8% of males around the world. Take a screen out into bright sunlight and try to read text that's similar brightness to its background, and you can start to understand that contrast issues affect everyone.
