如何为Shopify博客添加上一篇和下一篇按钮？

在sections/article-template.liquid里的{{ article.content }}下面添加如下代码：

<div class="blognav">
{% if blog.next_article %}
<div style="float: left; clear: left">
&lt;&lt; <a rel="next" href="{{ blog.next_article.url }}">{{ blog.next_article.title }}</a>
</div>
{% endif %}
{% if blog.previous_article %}
<div style="float: right; clear: right">
<a rel="prev" href="{{ blog.previous_article.url }}">{{ blog.previous_article.title }}</a> &gt;&gt;
</div>
{% endif %}
</div>
