Features of this site

Descriptive link text
When the author of a site uses descriptive link text, all links on the page will make sense even when read out of context. For users of assistive technology (e.g. Screen-readers) this can allow them to quickly jump through pages of text to find relevant links.

Meaningful ALT attribute on images
Most images on this site contain additional ‘alternate’ text that is stored with the image. This allows users who otherwise wouldn’t be able to see the image access to the stored information. Although this can help users of assistive technology (e.g. Screen-readers), this also applies to visitors who disable images because of a slow internet connection.

Any image that is considered purely decorative will have a blank alternate text (e.g. alt=””). This reduces the amount of unnecessary content on the page.
