### Putting images in context ### Putting images in context
Alt text should be limited to describing content of the image. It lacks context. To make things worse, images can contain a great deal of information. Sighted people can "filter" this information and find areas to focus on; alt text should capture this detail. However, sighted users' understanding of this detail can be informed by surrounding less-essential detail. Alt text should be limited to describing content of the image. It lacks context.

The WCAG recommends a max line length of 80 characters (40 characters for <abbr title="Chinese, Japanese, and Korean">CJK</abbr> languages) as a AAA guideline in [Success Criterion 1.4.8 Visual Presentation](https://www.w3.org/TR/WCAG22/#visual-presentation). However, studies seem to have mixed results; some people find it easier to read lines around 90 characters long, while others struggle beyond the 50-character mark.

Some of my links display long link-text; short line lengths can break these link texts too much, which can slightly hurt readability. Of course, narrow viewports will obviously make short line lengths non-negotiable. I decided to give article bodies a width of `38em`, which typically corresponds to just under 90 characters. I opted to use `em` instead of `ch` for consistency and for better compatibility with some uncommon browsers (NetSurf, Dillo, and others).
