How can I quickly fix a high cumulative layout shift issue?

CLS is currently sitting at .33 - poor. I have to be honest, I have done a bit of reading this morning to try and resolve this issue myself but I am finding it complicated. Are you able to give me a quick simple fix to resolve the issue please? Thank you, I would really appreciate any help and support.

Have you gone through page insights to see what are the offending blocks?

There are no universal quick fixes
