Using JQuery to reveal using a slide up effect - Jason Gill. The slideUp() method in JQuery is intended to hide the element rather than reveal it. It is basically the opposite of slideDown() which “unhides” your element by sliding it down. As you can see on this blog, I have an “About Jason Gill” tab in my heading. When clicked, this tab reveals information about who I am by sliding upward. In figuring out how to do this, I of course consulted the Google gods and came up with a lot of people asking how, but few people providing answers. So, I’ve decided to post the solution I finally came up with hoping it will benefit others. Basically, I am using two different effects to create what looks like one effect.
