CSS Flex and Grid were only the names I had heard, but this time I learned about the concept and how to make it responsive, so it was a useful time. The JavaScript basics video I saw on YouTube became a signal, so I took the lectures "Getting Started with Interactive Web Development Properly", "SVG Master", and CSS Flex & Grid, and I am satisfied with all three lectures. I will watch them repeatedly and make good use of what I learned~! I am also looking forward to the next scroll lecture.
