What are those three vertical dots and three/four horizontal bars on web pages.
Yes suddenly I started to see those and didn't realize immediately what they were for.
The Hamburger button. Yes that is what they are called. The hamburger button, so named for its unintentional resemblance to a hamburger, is a button typically placed in a top corner of a graphical user interface.
Its function is to toggle a menu or navigation bar between being collapsed behind the button or displayed on the screen. ... The wider button may be reduced to three vertically stacked dots.
