Material Gaze is a Stargazer child theme, which is inspired by Google’s Material Design. It comes with an alternate color scheme and extra custom headers designed just for this theme. There’s a lot of really nice design touches that set it apart from its parent theme.
Trailing Spaces is a Saga child theme. The color and font choices have helped make it one of my favorites. I think it’d be great for tech bloggers.
