Today, you're going to create your own color picker.
Write the function `pick` which turns the screen into a `hsl` color picker, varying the `hue` and `luminosity` of according to the position of the mouse, which:
Write the function `pick` which turns the screen into a `hsl` color picker. It will vary the `hue` and `luminosity` according to the position of the mouse.
- changes the `background` color of the `body`, so the `hsl` value is different on each mouse position on the screen:
- on the axis X, the hue value has to vary between 0 and 360
- on the axis Y, the luminosity value has to vary between 0 and 100
- displays those 3 values using the `text` class:
- the full `hsl` value in a `div` with the class `hsl` in the middle of the screen
- the `hue` value in a `div` with the class `hue` in the top right corner of the screen
- the `luminosity` value in a `div` with the class `luminosity` in the bottom left corner of the screen
- copies that value in the clipboard on click
- displays two SVG lines, with respective ids `axisX` and `axisY`, following the cursor like so:
- the axisX has to set the attributes `x1` and `x2` to the mouse X position
- the axisY has to set the attributes `y1` and `y2` to the mouse Y position
The `background` color of the `body` will change based on the position of the mouse on the screen.
- The X axis will vary the hue value between 0 and 360.
- The Y axis will vary the luminosity value between 0 and 100.
> Here is how a hsl value is formatted: `hsl(45, 50%, 35%)`
You'll need to display these three values:
- The full `hsl` value in a `div`, which has the class `hsl` in the middle of the screen.
- The `hue` value in a `div` with the class `hue` in the top right corner of the screen.
- The `luminosity` value will be displayed in the bottom left corner of the screen, in a `div` with the class `luminosity`.
> Use `Math.round()` to round the values
When the mouse is clicked, the value of the `hsl` will need to copied to the clipboard.
### Notions
Two SVG lines with ids `axisX` and `axisY` will need to follow the cursor, like really long cross hairs.
- the `axisX` attributes `x1` and `x2` need to be set to the X position of the cursor.
- the `axisY` attributes `y1` and `y2` need to be set to the Y position of the cursor.
- Take a look at the [HSL section](https://developer.mozilla.org/en-US/docs/Web/HTML/Applying_color)

> Use `Math.round()` to round the values.
