            <PhotoBrowser photos={photos} thumbs={thumbs} ref={standalone} />
            <Button fill onClick={() => standalone.current.open()}>
              Standalone
            </Button>
          </div>
          <div>
            <PhotoBrowser photos={photos} thumbs={thumbs} type="popup" ref={popup} />
            <Button fill onClick={() => popup.current.open()}>
              Popup
            </Button>
          </div>
          <div>
            <PhotoBrowser
              photos={photos}
              thumbs={thumbs}
              type="page"
              pageBackLinkText="Back"
              ref={page}
            />
            <Button fill onClick={() => page.current.open()}>
              Page
            </Button>
          </div>

            <Button fill onClick={() => standaloneDark.current.open()}>
              Standalone
            </Button>
          </div>
          <div>
            <PhotoBrowser

              thumbs={thumbs}
              theme="dark"
              type="popup"
              ref={popupDark}
            />
            <Button fill onClick={() => popupDark.current.open()}>
