+The theme supports custom css, you can override anything you want by redefining classes in the `assets/css/custom.css` file.
+
+For instance, changing the main width can be done as follows: 
+
+```css
+:root {
+    --main-width: 1024px; /* overrides default of 780px */
+}
+```
+
+Note that backward incompatible changes in the CSS will likely not happen, but there might be cases in the future where 
+backward compatibility is not possible. If you are overriding a huge amount of CSS I suggest you forking the project instead of 
+defining it here.
