The closest() method in jQuery is used to return the first ancestor of the selected element.SyntaxThe syntax is as follows −$(selector).closest(filter)ExampleLet us now see an example to implement the jQuery closest() method −    .demo * {       display: block;       border: 2px solid blue;       padding: 5px;       margin: 15px;    }    $(document).ready(function(){       $("span").closest("ol").css({"background-color": "orange", "color": "black","border": "3px dashed orange"});    }); body ol ol ol li span OutputThis will produce the following output −

The fadeIn() method in jQuery is used to change the opacity, for selected elements, from hidden to visible.SyntaxThe syntax is as follows −$(selector).fadeIn(speed, easing, callback)ExampleAbove, speed is the speed of the fading effect. The easing can be swing or linear for speed at different animation points. Callback is the function to be executed after the method gets finished.Let us now see an example to implement the jQuery fadeIn() method −    $(document).ready(function(){       $(".btnout").click(function(){          $("div").fadeOut();       });       $(".btnin").click(function(){          $("div").fadeIn();     ...
