you find if called indent. indeed, there many interactive functions start indent. find them m-x indent tab. can find documentation c-h ?, if try c-h d ret indent ret search in functions' documentation, or m-x apropos ret foo ret find them.
the following built in , work different languages (just tried elisp, python , javascript):
m-x indent-regionformats selected region,indent-sexpformats current expression
there no global option configure indentation, need dive in each mode's options. there options (setq html-tab-width 4).
edit: hints: (setq tab-width 8), (setq c-set-style "k&r"), (setq c-basic-offset 8) , emacs' built in c-mode or gnu indent can switch styles: https://www.gnu.org/software/emacs/manual/html_mono/ccmode.html#choosing-a-style or https://www.gnu.org/software/indent/manual/indent.html#sec4
