I'm working on a lightweight text slider for use on WordPress sites. The slider's context appears to be an issue: on some sites, contained within a widget, the animation works perfectly. On others, using a different WP theme, when the animation runs, the "slides" do slide, but instead of sliding out of view, they just slide to the far right side of the screen, underneath the other content. The "offscreen" slides remain partially visible under that content.
I am pretty sure this is concerned with the distance the "slides" move, which I'll admit I don't fully understand. The basic code was forked off of another similar pen, I think, but a long time ago. The basic issue here is that the available plugs for basic WP animation are beasts: tons and tons of code, enough to slow page loading times by many seconds. TweenLIte, of course, is extremely lightweight.
I'd be grateful if someone could explain the movement pieces of this TweenLite animation, so that I could figure out where the "offscreen" slides need to "go" to remain invisible.
