Make DOM elements invisible during modification
When several properties of a DOM (Document Object Model) element must be modified, each style or content change will generate a repaint or a reflow. It is therefore usually more economical to:
- make the element invisible (set display to none) (1 reflow)
- modify the element properties and then make it visible again (1 reflow)
Thus resulting in a maximum of 2 reflows.
