A couple of days ago I updated Lightword, the theme that I’ve been using on this blog for quite a while now. Unfortunately when I did the update I lost all of my customizations, including my logo and Adsense code.  So I went looking for a solution.

Little did I know, WordPress has supported a feature called “child themes” for some time now.  The idea is that you create a new theme, which is as simple as creating a new directory with a single CSS file called style.css, and add a comment to the new CSS file specifying the name of the parent theme.  You can read all about how to create a child theme here.
