Reflow

{{GlossarySidebar}} 

Reflow happens when a {{glossary("browser")}}  recalculates the position and geometry of certain parts of a webpage, such as after an update on an interactive site. This tends to be followed by repainting, which is when the browser redraws the webpage to show the resulting visual updates.
