Answer 1

Is this what you're trying to accomplish? Here's the jsFiddle

HTML:

<input type="button" id="toggle" value="toggle" />
<br />
<div id="classContainer">

    <div id = "class1">

    </div>
    <div id = "class2">
    </div>
</div>

jQuery:

$("#toggle").click(function (){
    if ($("#class1").is(":visible")) {
        $("#class1").fadeOut();
        $("#class2").fadeIn();
    }
    else {
        $("#class1").fadeIn();
        $("#class2").fadeOut();
    }
 });

CSS:

#classContainer
{
    position: relative;
}

#class1, #class2
{
    height: 100px;
    width: 100px;
    position: absolute;
    top: 0;
    left: 0;
}

#class1
{
    background-color: red;
    display: none;
}

#class2
{
    background-color: blue;
}

Check out the color plugin for jQuery: https://github.com/jquery/jquery-color

Answer 3

Try fadeIn.

$(".myClass").fadeIn("slow");

Although depending on the complexity you may need jQuery UI as other have mentioned.

Answer 4

jQuery UI has a toggleClass function that has an argument for duration:

For example, I do this on one of my sites (fade in/out the light class and fade/in out the dark class):

$('body').toggleClass('light', 250).toggleClass('dark', 250);
