I listened to this substantial lecture all the way to the end. The curriculum is so well-structured that anyone who wants to achieve beyond beginner level skills absolutely must take this course. I think it would have been a substantial lecture even for intermediate learners. The lecture is good enough to be worth listening to at that level. If you're a beginner or novice, you absolutely must take the core theory lectures. It felt like it filled in the gaps in my knowledge. I think you need to listen to it even more if you want to easily follow the responsive landing page content that comes later. They do explain things during the landing page section as well, but if you listen to this first and then proceed, you'll understand much more easily. There may be differences depending on who's listening, but for me, I thought it was just the right lecture. The explanations were excellent so I understood well, and it was a lecture that's also necessary for practical application. It helped me a lot. Thank you for the great lecture.
