cookbook assignment

Would appreciate any suggestions on refactoring or ways of simplifying my code. This assignment was pretty hard for me and I think my messy code reflects that a bit. I also noticed a really weird bug yesterday that treats the recipe_id and ingredient_id as string values rather than integers. I have no idea why it is doing this!
For all of these `h*` elements that share rules like `font-family: "Raleway"`, you can do a seperate declaration that includes all of them, each selector seperated by commas.

```css
h1, h2, h3 {
  text-align: center;
  color: #444;
  font-family: "Raleway";
}
```

Then separately change the `font-size` for each of them the way you did. This approach is more DRY.
