The basic org-mode headers
* Heading
** Sub-heading
* Another Heading
get converted to html like this
Heading
1.2 Sub-heading
Another Heading
(but imagine them larger and in h1 h2 fonts and sizes). How do you turn this off so that the headings are not numbered in the output html?
Oleg's answer allows you to disable section numbering for all exports at all times. However if you only want to disable numbering on export for a single file you can use the following:
#+OPTIONS: num:nil
If you want to limit it to only a certain depth you can replace nil with an integer specifying up to which headline you want the numbers to appear. For example #+options: num:1
would turn your sample into:
1. Heading
Sub-Heading
2. Another Heading
See Export Setting for the details and other export options that can be set on a per-file basis.
See HTML Specific Settings for HTML specific ones.
