只需按照以下步骤操作即可获得所需的结果。

1. <header>在nav之后关闭
2. 将评论框移到iframe下方
3. 使用间距、宽度、高度和网格来正确对齐。

var disqus_config = function() {
    this.page.url = 'http://example.com/2017/08/02/postid=998'; // Replace PAGE_URL with your page's canonical URL variable
    this.page.identifier = '/2017/08/02/postid=998'; // Replace PAGE_IDENTIFIER with your page's unique identifier variable
};

(function() { // DON'T EDIT BELOW THIS LINE
    var d = document,
        s = d.createElement('script');
    s.src = 'https://coinspy.disqus.com/embed.js';
    s.setAttribute('data-timestamp', +new Date());
    (d.head || d.body).appendChild(s);
})();
