  Hello,
  I would like to change the font of the footers.
  How to proceed?
  thank you

By the footer, do you mean the status bar?

Oh, that's the footnote? Today's nightly includes #4454.

Pinging @poire-z because I don't recall otoh if the popup footnote has a custom CSS mechanism as well.

No custom CSS in frontend/ui/widget/footnotewidget.lua, only a hardcoded one.
And the font size does not come from it, it's the one provided as the default font size to MuPDF.

koreader/frontend/ui/widget/footnotewidget.lua

Lines 178 to 181 in bba7635

	-- We may use a font size a bit smaller than the document one (because
	-- footnotes are usually smaller, and because NotoSans is a bit on the
	-- larger size when compared to other fonts at the same size)
	local font_size = self.doc_font_size - 2

@davicraquette : you can try changing the -2 here. Use -5 or -8 if you want it smaller.
As in my comment in that code, it looks like your main font is on the smaller side of fonts :) Or your book has some CSS that make that body text smaller, and we won't be able to know when deciding for the font size of footnotes popup...

We could add a manual setting if needed:
local font_size = self.doc_font_size - 2 + (G_reader_setting.readSetting("footnote_popup_font_size_diff") or 0)
or do some ugly font metric calculations (which may be wrong anyway given metrics quality) to find the best NotoSans font size to use... but again, this will still suck if the book has p {font-size: 90%}

Changing font size will soon be possible with a new menu item, see #4482.

Changing the font itself (to answer https://www.mobileread.com/forums/showthread.php?t=313043 too) is more complicated:

Lines 22 to 40 in c327069

	-- If we wanted to use the default font set for the book,
	-- we'd need to add a few functions to crengine and cre.cpp
	-- to get the font files paths (for each font, regular, italic,
	-- bold...) so we can pass them to MuPDF with:
	-- @font-face {
	-- font-family: 'KOReader Footnote Font';
	-- src: url("%1");
	-- }
	-- @font-face {
	-- font-family: 'KOReader Footnote Font';
	-- src: url("%2");
	-- font-style: italic;
	-- }
	-- body {
	-- font-family: 'KOReader Footnote Font';
	-- }
	-- But it looks quite fine if we use "Noto Sans": the difference in font look
	-- (Sans, vs probably Serif in the book) will help noticing this is a KOReader
	-- UI element, and somehow justify the difference in looks.
