- A rendering process in which the browser redraws elements on the screen without changing their layout or position, typically triggered by visual property changes such as color, background, visibility, or opacity. During a repaint, the browser updates the pixel representation of affected elements while maintaining their existing geometry and positioning in the document flow. Repaints are generally less expensive than reflows (which involve layout recalculation), but they can still impact performance when occurring frequently or affecting large portions of a page.
