blur
Description
The blur of HTMLOrSVGElement for JS moves the focus to the viewport. Use of this method is discouraged; if you want to focus the viewport, call the focus() method on the Document's document element.
Do not use this method to hide the focus ring if you find the focus ring unsightly. Instead, use the :focus-visible pseudo-class to override the 'outline' property, and provide a different way to show what element is focused. Be aware that if an alternative focusing style isn't made available, the page will be significantly less usable for people who primarily navigate pages using a keyboard, or those with reduced vision who use focus outlines to help them navigate the page.
Syntax
element.blur()
