A quick pass on how to create 16 different shapes in CSS, and many more that can be inferred from those. A slower version of • Shapes in CSS (1min) --- Music credit: Happiness, by Bensound.
That one is a fun one. If you want to learn more about that splash/stain shape, check this other video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o9Z41vGvfOA.html Or if you prefer, I also wrote an article about the creation process: alvaromontoro.com/blog/68018/creating-a-splash-effect-with-html-and-css
I don't know of courses that teach CSS Art in particular (or CSS through CSS Art), but there are a couple of CSS courses that I would recommend: - MDN Tutorial: it goes from the beginning to more complex concepts. developer.mozilla.org/en-US/docs/Learn/CSS/First_steps - Estelle Weyl's CSS workshop: an in-depth course that has been updated to include the latest CSS changes. estelle.github.io/ Apart from that, my recommendation would be to practice. If you find a website (or a drawing) you like, replicate it with HTML+CSS. And if you get stuck (and it's a website), inspect the original code and see how it was done.
