javascript - Hiding an object using css -


i trying hide vertical bar have created in jquery flot graph when mouse not within bounds of grid. set me horizontal bounds grid such: horizontalbounds = [leftoffset, plot.width() + leftoffset];. used if statement "if mouse within vertical bounds, verticalbar.css." 

if (position.pagex >= horizontalbounds[0] && position.pagex <= horizontalbounds[1]) {             if (typeof verticalbar !== "undefined" && verticalbar !== null) {               verticalbar.css({                 transform: "translate(" + position.pagex + "px, 0px)"               });             }

below css code (which in javascript file; don't ask...). need hide verticalbar when mouse not within horizontal bounds? thinking add attribute `visibility: hidden' verticalbar.css, can't figure out how that. hints?

verticalbar.css({               backgroundcolor: "#f7e4e6",               width: "1px",               height: "100%",               position: "absolute",               padding: 0,               margin: 0,               left: 0,               transform: "translatex(" + plot.getplotoffset().left + "px)"             });           }

try using "display:none;" in css.
