page level grid font

Is it possible to change the rowheight and checkbox size on a given page without editing it globally?

Please, try to use the following css to change the row’s height:

div.gridbox table.row20px tr td{ height: 25px; }

Checkboxes in grid are the simple images so the only way is to resize the original images of the checkboxes.

Thank you.
I really need the check-box to be larger as this is being used on a tablet and the default size it too small. Where can I change the image size and if change will the visual behavior be the same?

You may try to use your own custom images or change the the sizes of the images in any editor.
