Test whether or not the page is the home page
You can test to see if the current page is the home page with following code.
{% if _page.isHome %}
{% endif %}
An example use case could be to include specific CSS for the home page.
{% if _page.isHome %}
<link type="text/css" rel="stylesheet" href="/path/to/file.css">
{% endif %}
Test and see if the page is not the home page.
{% if _page.isHome == false %}
<p>This is not the home page.</p>
{% endif %}
An example could be to only include the breadcrumb text if the current page is not the home page.
{% if _page.isHome == false %}
{{ _page.breadcrumb() }}
{% endif %}
