the differences is between a full tab and spaces. It's not Github, it's how HTML presents this in the view. My suspicion is that it was the Ruby kids who really started sharing a lot of code on Github and in the code views it looked really bad. Then it became standard to move to two spaces, versus a full tab. 

In your Sublime settings, use the following:

```json
"tab_size": 2,
```

For the purposes of this exercise, I am willing to look past this. But let's try to clean this up for current and future assignments.
