/*
Theme Name: Timbba Blog (Appro child)
Theme URI: https://timbba.com/
Description: Child theme of Appro for blog.timbba.com. Gives the blog the main timbba.com page's header, footer, typeface, type scale and page design - tinted section bands, cards, the "Get in touch" section - so the two read as one site. Every front-end template is this theme's own; the rules below are ported from, or built on, the main page's stylesheet. Being a child theme, nothing here is touched by WordPress, plugin or Appro updates.
