title: Changing iframe src with effect?
body: <p>I'm making a simple web app, and I want to have navigation links that, instead of using an <code>&lt;a&gt;</code> tag, change the SRC of an iframe. When this happens, is there a way to make the old page "slide up" and out of the iframe quickly, then let the new page load? If possible, I'd like to use only HTML, Javascript, and CSS.</p>
