Additional Customization and Icon Placement

Would there be a way to make the caption in the lightbox go onto the second line when it is long instead of having the ellipses? Additionally, is there a way to make the icons for the menu in the lightbox stay on the top right corner? When the webpage has a narrower viewport or when the caption is too wide, it pushes the icons below the caption. I tried adding float: right in custom CSS, but it did not make the change I needed. I also looked through the plug-in files in the editor to look into making customization there, but I couldn’t seem to find what I needed to change.

Thanks,
Aaron
