## Pick & click
|
|
|
|
### Instructions
|
|
|
|
Today, you're going to create your own color picker.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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` and `text` 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` and `text`.
|
|
|
|
When the mouse is clicked, the value of the `hsl` will need to be copied to the clipboard.
|
|
|
|
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.
|
|
|
|
> The formatting of a `hsl` value: `hsl(45, 50%, 35%)`.
|
|
|
|
> Use `Math.round()` to round the values.
