What is the difference between reflow and repaint in CSS?
Reflow is the process of recalculating the positions and sizes of elements in the DOM, while repaint is about updating the visual representation without changing the layout.
Can you give me an example of when reflow occurs?
Sure! Reflow occurs when you change the size of the browser window or when you add or remove elements from the DOM.
What about repaint? When does that happen?
Repaint happens when you change the color or visibility of an element, like changing its background color, without affecting its layout.
How can I minimize reflow and repaint in my web applications?
You can minimize reflow and repaint by batching DOM changes, using CSS transitions, and avoiding layout thrashing.
