Question

How to center the caption of a grid without changing the css (which is global) ?
By defaut the caption is on left.

Answer 1

I think the code which center the caption could be about the following

$("#grid").closest("div.ui-jqgrid-view")
    .children("div.ui-jqgrid-titlebar")
    .css("text-align", "center")
    .children("span.ui-jqgrid-title")
    .css("float", "none");

See the demo:
