比如该帖子底部的“展开隐藏内容”按钮：

https://hu60.cn/q.php/bbs.topic.96470.html

已经接到超过3起用户反馈，他们最开始没看到这个“展开隐藏内容”按钮，经过我的提醒才找到。

background-color: #f0ad4e;
border-color: #eea236;
padding: 20px;

使用手机在百度上随便搜索一篇文章，点进去就会有大量的“阅读全文”按钮作为参考

点击页面任何地方都能触发不就行了

$("body").click(function(){
　　　　$('#floor_fold_bar_0 button').trigger("click");　　
});

这样搞更加不明显了

@ponyoung，哈 我也觉得 其实就是颜色太接近背景白色 存在感太低造成

这个怎么样
