It seems like you made a good lecture.. but I don't think I'll be able to study by watching the videos in a place where there are foreigners.. It might not be intentional, but.. your Naver and Google IDs seem quite inappropriate. 'niganiga', 'nigayo' .. I think it wouldn't be a bad idea to consider changing your ID names... I thought it wouldn't be true when I saw your Naver ID, but I was really surprised and panicked when I saw your Google ID.

For beginners and web developers, HTML and CSS feel unfamiliar and vast. 
In particular, CSS is also an object of fear(?) for developers. 
However, if you know the principles and core contents of HTML and CSS well, you can relieve some of those worries. In this lecture, you can learn the important concepts of HTML and CSS through source code.

Core guide for HTML, CSS development

First of all, I apologize for the inconvenience you may have felt while watching the lecture.
Of course, I didn't mean it..(I meant 'niga' to mean 'you are..')

I think it's a word that can be easily misunderstood.
Thanks to you, I feel it seriously. I should change my ID right away.

Thank you for your sincere advice.
