My desktop users were complaining about the enormous full-width individual video size that displays when you click on a video in the video collection. I used this rough custom css to reduce the size:
.lesson-video-wrapper {width:640px!important;
height:360px!important;
margin:5% 20%}
and the page now looks like the screenshot attached (or visit the page here:https://relspec.com/video-library/v/powerful-ultrasonics-clean-blind-holes). However, this has now messed up how the video looks on a mobile phone. I tried to refine with some @media statements but then everything reverts to the original 100% width. Any suggestions?
