Answer by Hamson for hover effect on div using jquery

As the ".section" is hidden, your mouse leaves the .section. This is why it blinks.And as you show a .hidden, you need to fire your event when you leave the .hiddenHere is something that may solve your issue: (http://jsfiddle.net/hdehzec0/7/) :

$(document).ready(function () {    $(".inner").hide();    $(".section").mouseenter(function () {        $(this).next(".inner").show();        $(this).hide();    });    $(".inner").mouseleave(function () {        $(this).hide();        $(".section").show();    });});
