how to change the order of each section?

[zeyunlu]

Seems the default "About", "Blogs", "Projects", "Publications" are in alphabet order, how do I make it such as "Blogs", "About", "Nancy", "Information" ?

Thanks.

The order of the sections in the navbar is set in header.html.
Actually the first section is about (see from line 25):

<!-- About -->
<li class="nav-item {% if page.title == 'about' %}active{% endif %}">
  <a class="nav-link" href="{{ '/' | relative_url }}">
    about
    {% if page.title == "about" %}
    <span class="sr-only">(current)</span>
    {% endif %}
  </a>
</li>

Then blog (see from line 34):

{% if site.blog_name %}
<!-- Blog -->
<li class="nav-item {% if page.url contains 'blog' %}active{% endif %}">
  <a class="nav-link" href="{{ '/blog/' | relative_url }}">
    blog
    {% if page.title == "blog" %}
    <span class="sr-only">(current)</span>
    {% endif %}
  </a>
</li>
{% endif %}

And finally the rest of pages in alphabet order (see from line 45):

<!-- Other pages -->
{% assign sorted_pages = site.pages | sort: "title" %}
{% for p in sorted_pages %}
{% if p.nav and p.autogen == nil %}
<li class="nav-item {% if page.title == p.title %}active{% endif %}">
  <a class="nav-link" href="{{ p.url | relative_url }}">
    {{ p.title }}
    {% if page.title == p.title %}
    <span class="sr-only">(current)</span>
    {% endif %}
  </a>
</li>
{% endif %}
{% endfor %}

If you want to change the order of the sections, you should simply reorder these blocks of code how you prefer!

This exactly answers my questions! Thank you so much!

Where can I find the 'header.html'?
The link in the above answer is not valid.

This was a very old answer. If you check the same directory you'll find a file with the same name, different extension header.liquid. That is the one. A lot of files were renamed .liquid in #2048.
