Responsive columns + HTML

Great the video is now working but still the html still just shows the red lightening symbol only, with no input or output.

With that aside I am not making any headway with responsive columns.I can when I use your templates but they don’t do what I need, I would like to create a video wall of 50 + videos of 6 thumbnails with titles beneath each, to each row, reducing in sequence to just 2 per row for mobile. I have tried to emulate the templates to no avail How do I achieve this please from scratch. I can get the videos playing through one Lightbox that spans the full width of the mobile but getting the columns to break correctly escapes me.

Okay, so you want 6 items across on desktop, then going down to 2 items on mobile?

If that’s the case I can quickly whip up a video and project to show you how to do this :blush: Just let me know!

Thanks Dan but the bot explained it very well. The bot and the dot

Video: 4-6 on desktop 1-2 on mobile
