Developers often spend significant time on styling elements using CSS, which, despite its complexity, can be mastered through practice such as recreating images with pure CSS. This tutorial demonstrates creating a yin-yang symbol using only one line of HTML and CSS, employing pseudo-classes and border properties to achieve the desired effect. The process involves creating a circular shape with CSS borders and using pseudo-elements to add inner circles, followed by a simple animation to make the symbol spin indefinitely. This exercise not only enhances styling skills but also serves as a foundational challenge to tackle more complex projects.
