I agree with @ijgnd. You seem to be really motivated to make the most of your Anki cards. As someone in a related position, I can wholeheartedly recommend using that motivation to teach yourself the associated tools while applying them to your very own real life problems.
I have learned so much thanks to Anki and the content of my flashcards is only a portion of it.
If you don’t like learning from videos like me, I recommend w3schools.com for web development stuff like HTML and CSS. They don’t only have interactive turorials but also highly comprehensive references to look up tags, properties and so on.
