Question

I want to make something similar with this

When you click on “description” text appears.
I want to create this effect with jQuery, how can I make this?

Answer 1

Perhaps a fadeToggle() ?

<a href="#" id="appear">Clicky</a>
    <p class="textTo" style="display: none;">Hello World!</p>

<script type="text/javascript">
$("#appear").click(function() {
   $(".textTo").fadeToggle();
});
</script>

check out the working fiddle:

and the api:

http://api.jquery.com/fadeToggle/

the api shows a bit more.

for example there are some parameters to pass controlling animation speed, type, etc.
