Site URL: http://sciencetutors.co.uk Hi, I am trying to edit code to change my banner on the front page so that is the right size for mobile but it doesn’t seem to be doing anything and don’t know why! I got this code from a youtube video and tried some others too and they also did nothing! Any advice needed!

Site URL: http://www.sciencetutors.co.uk Hi! The Banner is correct on a computer but on a mobile site half of it is cut off - any ideas on how to resolve this so it can be seen fully on mobile? Thanks so much, Charlotte
