If you need support from Yola please contact us via email@example.com or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
If you make your own custom banner, then you can adjust the height through your banner maker or image program. However, you need to be mindful that the banner size of the template is static. So, if you make your banner smaller, there will simply be a gap between your banner and the content of your pages.
I hope this answers your question. If you need further clarification, please don't hesitate to ask.
