Topbox by @willwood is great, I have everything working but the lightbox only fills half the screen. I have followed Will’s instructions on the tutorial page to overcome this issue:
-Disable extensions in your web browser (like Ad Blocker Plus, Click2Play, script blocker, etc.)
-Check the content going into the TopBox is responsive (flexible) and compatible with lightboxes or modal windows
-Ensure the correct content type has been selected (e.g. AJAX for AJAX content, images for image content)
I am using stacks to input content, which I assume are responsive and compatible with the lightbox.
I’d greatly appreciate any help to fix this.
