+
+When you use diff annotations (insert/remove), Phiki will automatically try to find `markup.inserted` and `markup.deleted` colors inside of your chosen theme(s) and add CSS variables to the `
` element.
+
+If it can't find them, it will fallback to the default background color of the theme.
+
+Phiki automatically adds the following CSS variables to the `
` element:
+
+- `--phiki-diff-insert-bg` - Background color for inserted lines
+- `--phiki-diff-insert-fg` - Text color for inserted lines
+- `--phiki-diff-remove-bg` - Background color for removed lines
+- `--phiki-diff-remove-fg` - Text color for removed lines
+
+You can use these variables in your CSS:
+
+```css
+.phiki .line.insert {
+    background-color: var(--phiki-diff-insert-bg);
+    color: var(--phiki-diff-insert-fg);
+}
+
+.phiki .line.remove {
+    background-color: var(--phiki-diff-remove-bg);
+    color: var(--phiki-diff-remove-fg);
+}
+```
+
+
+If you're using multiple themes, Phiki will also add CSS variables for each theme so you can style them differently in dark mode, for example.
+
+
+```css
+@media (prefers-color-scheme: dark) {
+    .phiki .line.insert {
+        background-color: var(--phiki-dark-diff-insert-bg) !important;
