Hello,
One section of my one-page site disappears when the viewport shrinks to mobile size, approx 480 px. This is the only section of the site with v2 text elements in 2 columns side by side, one with text boxes and the other with a v2 video element. Please tell me the CSS or whatever I need to get the right column to stack below the left column when the viewport is 480 or below. Thanks!
