Build a Drum Machine

**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab. **User Stories:** 1. You should have a `div` element with an `id` of `drum-machine` that contains all other elements. 2. Inside the `#drum-machine` element you should have another `div` with an `id` of `pad-bank`. 3. Inside the `#drum-machine` element you should have a `p` element with an `id` of `display`. 4. Inside your `#pad-bank` element you should have nine clickable drum pad elements each with a class of `drum-pad`, a unique `id` that describes the audio clip the drum pad will be set up to trigger, and an inner text that corresponds to one of the following keys on the keyboard: `Q`, `W`, `E`, `A`, `S`, `D`, `Z`, `X`, `C`. The drum pads MUST be in this order. 5. Each `.drum-pad` should have an `audio` element which has a class of `clip`, a `src` attribute that points to an audio clip, and an `id` corresponding to the inner text of its parent `.drum-pad` element (e.g. `id="Q"`, `id="W"`, `id="E"` etc.). 6. When you click on a `.drum-pad` element, the audio clip contained in its child audio element should be triggered. 7. When you press the trigger key associated with each `.drum-pad`, the audio clip contained in its child audio element should be triggered (e.g. pressing the `Q` key should trigger the drum pad which contains the string `Q`, pressing the `W` key should trigger the drum pad which contains the string `W`, etc.). 8. When a `.drum-pad` is triggered, you should display a string describing the associated audio clip as the inner text of the `#display` element (each string must be unique). Some audio samples you can use for your drum machine can be found at `https://cdn.freecodecamp.org/curriculum/drum/<fileName>`, where `<fileName>` is as follows: | drum name | `fileName` | | --- | --- | | Heater 1 | `Heater-1.mp3` | | Heater 2 | `Heater-2.mp3` | | Heater 3 | `Heater-3.mp3` | | Heater 4 | `Heater-4_1.mp3` | | Clap | `Heater-6.mp3` | | Open-HH | `Dsc_Oh.mp3` | | Kick-n'-Hat | `Kick_n_Hat.mp3` | | Kick | `RP4_KICK_1.mp3` | | Closed-HH | `Cev_H2.mp3` |
