Why does org source block use different font than text?

The reason there's different highlight groups is so emacs can render source blocks the same way as buffers with just code. This is useful especially with org-variable-pitch-mode, where you can use proportional fonts for the main text and colored monospace fonts for source blocks. You can check which fonts specifically are used for the block with: M-x describe-face RET org-block RET

just to add to this. the font and style can be set for *any* face and every bit of text has some face. The function `list-faces-display` will show you all the different ones with their current setting.

How can I turn of this feature, I want source block to use default font. Current default font is the font text uses

You can try running `M-x customize-face RET variable-pitch RET` then unchecking the "Font Family" attribute then clicking `Apply and Save` There might be a better way to go about this but that's essentially how I solved it :P You can also try editing the `org-block` face instead of `variable-pitch` if you only want this font change to only happen specifically for org blocks

Short answer: The theme you chose made it that way. > How can I turn of this feature, I want source block to use default font. Use a different theme, or figure out what that theme did which you don't like, and change it.

(deftheme default-black "Automatically created 2013-05-20.") (custom-theme-set-faces 'default-black '(default ((t (:inherit nil :stipple nil :background "Black" :foreground "White" :inverse-video nil :box nil :strike-t*hrough nil :overline nil :underline nil :slant normal :weight normal :width normal :height 105)))) '(highlight ((((class color) (min-colors 88) (background dark)) (:background "#111111")))) '(region ((nil (:background "#464740")))) '(hl-line ((nil (:background "#222222")))) '(yas-field-highlight-face ((nil (:background "#333399")))) '(js2-function-param-face ((t (:foreground "LightGoldenrod")))) '(font-lock-warning-face ((nil (:foreground "#ff6666")))) '(show-paren-match ((nil (:background "#333399")))) '(show-paren-mismatch ((((class color)) (:background "red"))))) (provide-theme 'default-black) That is all nothing else. Some others themes works fine, modus themes works fine. this one is not, Gruber darker also has the same problem

Your code is broken on old reddit, but I do see that you're changing the height of `default` in there. All's I can really say is: what you shows in the screenshot isn't the default. Therefore, something in your own config is doing the thing you don't want.

I found out that it is default behaviour of emacs. Try any default theme. Source block will look different

Just having your point on the face you want to change and doing customize-face will select that one.

(deftheme default-black "Automatically created 2013-05-20." (custom-theme-set-faces 'default-black '(default ((t (:inherit nil :stipple nil :background "Black" :foreground "White" :inverse-video nil :box nil :strike-t*hrough nil :overline nil :underline nil :slant normal :weight normal :width normal :height 105)))) '(highlight ((((class color) (min-colors 88) (background dark)) (:background "#111111")))) '(region ((nil (:background "#464740")))) '(hl-line ((nil (:background "#222222")))) '(yas-field-highlight-face ((nil (:background "#333399")))) '(js2-function-param-face ((t (:foreground "LightGoldenrod")))) '(font-lock-warning-face ((nil (:foreground "#ff6666")))) '(show-paren-match ((nil (:background "#333399")))) '(show-paren-mismatch ((((class color)) (:background "red")))))) (provide-theme 'default-black) Just formatting it.

It's by design.

Try to reproduce with `emacs -Q`.
