Algebra 103, Deep Algebra — handmade, no ads, no sign-ups. Every lecture is kept whole and shown whole: nothing is summarised, so what you see is the lecture as it was written. 36,943 words across 25 lectures, from polynomial rings and the Factor Theorem to number theory for algebra. Twenty-one ways through the same text, forty-six palettes on a white default with dark a click away, twelve layouts and colours you can set yourself. The source is native LaTeX, so the mathematics needed no repair at all: every formula is the author's own markup, rendered as written.
