This child theme enables you to make customizations while allowing for safe updates to the parent theme.
The parent theme's style.css is imported below. If you wish to make customizations, do one of the following:

Option A.) Remove the import below, and copy the contents of lightfast/style.css into this file, but leave the (above) child theme head in tact!
