Try to pair program ![:busts_in_silhouette:](https://forum.freecodecamp.com/images/emoji/emoji_one/busts_in_silhouette.png?v=3 ":busts_in_silhouette:") and write your own code ![:pencil:](https://forum.freecodecamp.com/images/emoji/emoji_one/pencil.png?v=3 ":pencil:")
+
+### Problem Explanation:
+
+This program is very simple, the trick is to remember how while looping works.

+
+* **Make sure your zoom settings are at `100%` or `default` otherwise tests sometimes fail. **
+
+## ![:speech_balloon:](https://forum.freecodecamp.com/images/emoji/emoji_one/speech_balloon.png?v=3 ":speech_balloon:") Hint: 1
+
+* You will initialise the loop first with x as: `$x: 1`

+## ![:speech_balloon:](https://forum.freecodecamp.com/images/emoji/emoji_one/speech_balloon.png?v=3 ":speech_balloon:") Hint: 2
+
+* See the example for `@while` syntax, `@while $x < 11`

+
+* to set class properties inside a loop we reference them enclosed by #{}, hence ere it will become: `.text-#{$x}`
