# Define an HTML Class in JSX
---
## Problem Explanation
- HTML and JSX may seem that they are exactly the same but there are a few differences between them.
- One of these differences is the naming convention.
- HTML attributes and event references in JSX become camelCase(onclick => onClick).
- There may also be some words reserved in JavaScript.For instance the word "class" cant be use to define HTML classes
in JSX.Therefore instead of using "class" you can use "className".

## Hints
### Hint 1
- You may want to change "class" to "className".
