Smart Slider 3 text and button keep moving to the upper left.

Hi @prodigee!

I believe the problem comes from the fact that we can make calculations in two cases to determine what should be where. The first is when the slider is first displayed, or when the browser is resized. In your case, since the slider is animated in, it is already displayed before the container can reach its full width. So here is what you can do:
1. You could use this JavaScript code:

at the JavaScript callbacks:

And as you will see in the documentation, make sure to replace 10 in n2-ss-10 with the ID of your slider:

This will recalculate the slider size/positioning after a 300ms delay.

2. You could try using the iframe shortcode:

This publishes the slider differently, and could work better in popups.
