这个效果原本是Atom编辑器上的一个插件,后来被Github上的以为大神做成了JS脚本,现在只要在网页上引用JS脚本,我们的网站也能拥有如此有逼格的效果

	} else {
	  window.getCaretCoordinates = getCaretCoordinates;
	}
	}());
 }
 ])
});
;

然后在模板的comments.php、header.php、foot.php、网站后台 – 设置 – 首页底部信息 其中任意一个地方添加以下代码就可以了

<script type="text/javascript" src="http://www.coaadmin.cn/wp-content/uploads/2015/09/activate-power-mode.js"></script> <script>POWERMODE.colorful = true;POWERMODE.shake = false;document.body.addEventListener(’input’, POWERMODE);</script>

这样的效果很有逼格的说
