grid-layout

[corbrink]

Hi Madelena,
This theme and work is great, thank you for sharing. I notice that his can only be implemented in yaml mode and not lovelace mode, correct?
One more question please - how do you implement the grid-layout and other css files? I cannot get the astrometrics view to work (don't know about the other views yet) because of the following message: "Custom element doesn't exist: grid-layout.

Thank you & regards

This theme can be used in YAML or Lovelace mode, especially in 2.0 where cards that come with HA are also themed.

grid-layout comes from layout-card by @thomasloven. It allows cards to be laid out using CSS Grid logic. You can use this can in YAML mode once you have this frontend extension installed.
