How to center figure caption in Sphinx?

[陳韋任]

Hi all,

 

Currently I use following syntax to put my figure on the document, .. figure:: ../Fig/Fig2_4.png :align: center caption   The figure itself is centered, but the caption below it is left align. Anyone can give me a hint on how to center the caption? Thanks!

You can put a class on the whole figure with :figclass: which you can then style in your CSS as you please.  The default theme has a "align-center" class which handily already has "text-align: center;" set for you.

Hi Rober,

  Thanks for your reply, but I don't understand what I should do. Could you give me an example code

to illustrate a little bit more? Say, what should I change in the code below? 

  .. figure:: ../Fig/Fig2_4.png
  :align: center

  caption

 Thanks again. :-)

Ugh, I checked back and ":align: center" and ":figclass: align-center" seem to have the same effect for HTML.  My guess would be that your theme omits a declaration such as the one found in basic.css:

.align-center {

    text-align: center;

}

If your theme has another class that features such an alignment clause (say, the CSS class is called foobar) then you can readily use it like this:

.. figure:: ../Fig/Fig2_4.png

   :figclass: foobar

For further advice on themes, please resort to sphinx-users (sphinx-dev is aimed at development of Sphinx.)
