When I am using jupyter notebook in vscode, I suddenly find the default font size become so small. So how to make the default font size bigger in the markdown cell? I have tried to google how to fix the problem, but I can't find the answer. Looking forward to your reply!

Update:
After I added code< font size=3 > on the first line of each markdown cell, the display became normal. But I think I should not everytime do it because it is a waste of time.
