This set of video tutorials mainly uses small cases to let everyone understand the knowledge points learned, and achieve different interactive effects through the reasonable use of knowledge points. This learning model that combines theory and practice allows everyone to better master theory and practical applications. This is also the teaching feature of Qianfeng HTML5 discipline. Only continuous practice can improve working methods and work experience. Micro cases include various projects related to HTML5, such as page layout, cool animation effects, game development, mobile development, front-end and back-end development, etc. There are many design contents and a wide range, covering various development needs. I hope this set of micro-case teaching videos can help everyone in their study and work.
