This course is a hands-on program focused on learning the core syntax and application methods of frontend web programming and applying them to actual portfolio creation. Learners will progressively master everything from basic syntax including HTML, CSS, and JavaScript to the latest frontend technologies, directly experiencing the process of web interface implementation and dynamic functionality handling. Additionally, through various examples frequently used in practice, learners can naturally acquire efficient coding techniques and real development workflows. Through this course, learners will move beyond simple syntax memorization to understand the connected workflow from web page planning–design–implementation, and based on this understanding, they can complete their own portfolio. Furthermore, this course will serve as a solid stepping stone for growing into a frontend developer, providing great help as an introductory course for learners new to web development and as a practical supplementary course for those looking to build hands-on experience.
