It irks me to find a paragraph break in the middle of a sentence in a document which is, broadly speaking, about doing html et al. correctly. One inconsistency that I have noticed blighting pages all over the web is defining a dark text colour and just assuming the background will be white. Try to view this using a 'dark theme' and often the undefined background colour will be dark but the original css will be respected for the text colour, meaning dark text on a dark background. Try to force a light text colour in the user/theme css and you mess up all the pages that did it right in the first place (i.e. specify text and background colour to have suitable contrast, or leave it all up to the browser/whatever to render nicely) I wonder if this is something that could be adressed by the tools in the article.
