Text Formatting ⇒ How to center section titles in article class

[Cham]

I need to change the section titles position in the article class. By default, the titles are located at left. I would prefer to have them centered. The subsection titles should stay at left (default position)

Here's a MWE to work with :

I know this should be pretty basic, but I'm still having difficulties with this kind of settup.

For such small changes, package sectsty can be used.

Thanks Johannes. The first solution gives a nicer output.

In both solutions, the space between the section number and its title seems to be too large. How can we reduce it ?

EDIT : I've found a command to add a dot, and allow to change the \quad space to another size. But then I'm not sure anymore what would be best looking. The dot also change the subsections number, but it's ugly in that case :

Code: Select all

\makeatletter \def\@seccntformat#1{\csname the#1\endcsname.\quad} \makeatother

If you don't want the period, just leave it out.

KOMA-script does not use big spaces.

%I did this and compiled. It works well with me.

@vaman: As I already explained: Please mark the code in your postings as code!

BTW: The shown code is the worst idea, because it changes the vertical spacing of the headings and it is not semantic but physical markup, that has to be done for every single \section, \subsection etc. command. All the other suggestions made above, i.e., the two examples by @Johannes, are better. So why do you show a new, not better suggestion to an old question, that has been answered well already? That's nonsense. Please answer new questions or old questions, that has not been answered already.
