I'm going to have fun completing the two-day theory class and the practical class on Saturday and Sunday. I thought the front-end, which I thought was difficult, was made so simple and fast and easy to create a responsive web using Bootstrap. I thought I should have taken it earlier if I had known I could master it in such a short time. I thought Bootstrap could only be used in the Bootstrap style, but I liked that the design can be changed to suit the user's needs, and there were many parts for customization in the practical content. I think this is a good lecture that is necessary not only for back-end developers like me, but also for those who are new to coding. I highly recommend it. Thank you, Youngcodi Kim. I'll be waiting for the next lecture.
