    i was wondering if is it possible to change the size of the blue box that appears with once you roll over the mouse??

    I’m wondering the same question as Jose.

    You need to specify the css for the Buttons of the LinkBar.

    as:

    linkBar.setStyle('linkButtonStyleName', 'myLinkButtonStyleName');

    css:

    .myLinkButtonStyleName {
    	paddingTop: 0;
    	paddingRight: 2;
    	paddingLeft: 2;
    	paddingBottom: 0;
    }
