+
+RSW editor doesn't isolate its styles from the parent styles. 
+It's a pretty common case when you use a global reset or normalize styles which
+remove bullets or numbers for lists. 
+To fix that, you should redefine these styles again:
+
+```css
+.rsw-ce ul {
+  list-style: disc;
+  padding-left: 2em;
+}
+
+.rsw-ce ol {
+  list-style: decimal;
+  padding-left: 2em;
+}
+```
