How to style only the pager-indexes of a GridView?

I use GridViews on several pages with pager-indexes in style "Next/Previous/Last/First". I need to apply special styles to them - color, font-size. The problem is if I use tr:last-of-type and the entries are less than one page, the styles go to the last row, I have anchors in the GridView.

Is there a way to select only the indexes if such exist?
