Styling beans_post_content_navigation( )

wp_link_pages has no styling as shown below. what would be the best way to apply page navigation styling to it so that its easier to navigate through post pages?

function beans_post_content_navigation() {

    echo wp_link_pages( array(
        'before' => beans_open_markup( 'beans_post_content_navigation', 'p', array( 'class' => 'uk-text-bold' ) ) . beans_output( 'beans_post_content_navigation_text', __( 'Pages:', 'tm-beans' ) ),
        'after'  => beans_close_markup( 'beans_post_content_navigation', 'p' ),
        'echo'   => false,
    ) );

}
