XMLHttpRequest reference
XMLHttpRequest is a native JavaScript object allowing further HTTP requests to be made from a page which has already loaded. It allows Microrequests to be made in response to user events in a web page, rather than requiring a complete page reload, making it possible to implement some notion of a rich client user interface, similar to desktop applications.
A nice collection of XMLHTTPRequest guides.

A bit off topic…but:
I just wanted to say that I really like your site & theme (which was found via the WP forum).
There was only one thing that bugged me about it (the whitespace on the right) until I read your ‘about’ page with the mention of Google Ads..
looks like my ad blocker must be working well :0)
Have just downloaded your theme and will have a closer look at it I’m just learning and want to make my own
Many thanks for sharing

The whitespace on the right is intentional. As most of the posts on this site are fairly short, I found that it makes them a bit more comfortable to read. If you want to remove/shrink the whitespace, you can amend the following in style.css:
#maincontent {
…
padding-right:230px;
Change 230px to 30px.
