Single Event Time Font Size

Hi, I don’t doubt this is something I have caused (somehow) but the Time part of the date/time shown on the single event view is a different font size to the rest of the date. If I use the customise option in Avada theme, I can dynamically change the date font size but the time part does not change. If I have set this in css somewhere, can you please point me to where the change would have been made? I’ve searched everywhere but I can’t find it.
