jQuery jqGrid Change The Font Size For Only The Caption On This Page

Question

In this jQuery & Coldfusion code, how would you change the font size of just the Caption? I would prefer not to update the CSS so it does it to every instance on every page of the Caption. Just the Caption on this page.

What @SOS write is absolutely correct.

In your case it is just this line

#gview_data_grid_display .ui-jqgrid-caption {
    font-size:  15px;
}

Note the gview_ prefix
