然后编辑主题,在主题页脚footer.php的body前加上下面的代码保存就可以了。

  1. <script src="<?php bloginfo('template_directory'); ?>/js/activate-power-mode.js "></script>
  2. <script>
  3. POWERMODE.colorful = true// make power mode colorful  
  4. POWERMODE.shake = false// turn off shake  
  5. document.body.addEventListener('input', POWERMODE);
  6. </script>
