Guidance on practicing html/css

Hi everyone! I’ve worked my way through all basic courses and am currently part way into the basic JavaScript course. I am finding it challenging to grasp the lesson on creating your own web layout with the colored blocks. For me, I would love some engaging practice routines that could get me in the flow of writing code from scratch and getting a better sense of order. I find myself having to essentially copy what’s going on in the fast paced videos and while I do understand what is happening, it is not really seeming to be getting me where I want to be as far as understanding it fully. I would love to hear what some of you have done to further practice this skill and really grasp it fully without having to rely on copying the videos. Thanks!
