- Tips and methods to reduce reflow and redraw operations
- How to avoid frequent reflow and repaint operations Reflow and repaint are two important operations when the browser renders the page. Reflow refers to the browser recalculating the position and size of elements based on changes in the DOM tree, while redrawing redraws the page based on the calculation results. These two operations consume a lot of computing resources and cause page performance to degrade. Therefore, avoiding frequent reflow and redraw operations is critical to optimizing web page performance. This article will introduce some effective methods to avoid frequent reflow and redraw operations.
