A minimalist design for the blog sidebar

His advantage is that, based on the customized sidebar content, it is displayed by default. Meanwhile, it prompts the column content and automatically plays in a loop. The duration can be customized, the display method can be customized via CSS, and the content can also be customized, making it very convenient and easy to operate. Visitors can learn about your categorized information during the loop playback process and can pause the automatic loop by selecting a specific column index to get detailed information about that particular section.
