How to customize headers and footers in Google Sheets?

Question

I just has a header to my Google Sheets like this:

How do I now change the size or color of these texts?

Thanks for your help!

Answer 1

At this time the feature to customize headers and footers doesn't include a way to set a custom formatting (font, color, size, effects like bold, italics, etc.).

One alternative is to use rows to hold the header / footer text and use the cell formatting or in cell text formatting to customize the "headers" and "footers"
