jRumble, it can make any element on the web page shake. Using this effect on your website will have a high chance of attracting the user's attention. The effect of this plug-in can be used on links or divs. You can set the shaking range, XY coordinates, shaking amplitude, etc. It can be set to vibrate when the mouse moves up or to vibrate all the time by default. The plug-in is quite customizable. PS: This plug-in still has some minor problems in IE
