 The basis of almost all lovelace cards is a `ha-card` element, so that's probably where you'd want to start.

+## Mod-card
+There are some cards where card-mod just won't work.
+Those cards often are not really *cards* at all, but change how other cards work. Examples include: `conditional`, `entity-filter`, `horizontal-stack` and `vertical-stack` as well as some custom cards, like `layout-card`, `auto-entities` and `state-switch` among others.

+For those cases, a special `mod-card` is provided as a workaround:

+```yaml
+type: custom:mod-card
+style: |
+  ha-card {
+    border: 1px solid green;
+  }
+card:

-### Why won't this work for some cards?
-The cards this doesn't work for often are not really *cards* at all, but change how other cards work. Examples include: `conditional`, `entity-filter`, `horizontal-stack` and `vertical-stack` as well as some custom cards, like `layout-card`, `auto-entities` and `state-switch` among others.

-Common for all those are that they have no `ha-card` element. A workaround for this is to put the card you want inside an entities card and mod that. For built-in cards, this can be done by setting the type of an entities row to `custom:hui-<type>-card`:
-
-```yaml
-type: entities
-style: |
-  ha-card {
-    --ha-card-background: red;
-    box-shadow: none;
-    background: none;
-  }
-  .card-content {
