### Instructions
Now that you created & identified properly the different sections of your being,
it's time to make it look more living-like! To achieve that, you're going to
style it with [CSS][0]. Create a CSS file, [link it][1] to your
`select-and-style.html`, and:
- target all the elements with the [universal selector][2] and style them with:
- `margin` of `0`
- `box-sizing` to `border-box`
- `opacity` of `0.85`
- target the `body` tag and style it with a `height` of `100vh` so it takes the
viewport height
- target all the `section` tags with the [type selector][3], and style it with:
- `padding` of `20px`
- `width` of `100%`
- `height` of `calc(100% / 3)` _(one third of the `body` height)_
- target each following element with the [`id` selector][4], using the `id` you
defined earlier for each section, and style it:
- `face` with a "cyan" `background-color`
- `upper-body` with a "blueviolet" `background-color`
- `lower-body` with a "lightsalmon" `background-color`
### Code examples
To style an element, you systematically have to declare [rulesets][5], composed of a property and a value.
Set the color of `div` tags to `"red"`:
```css
div {
color: red;
}
```
Set the `background-color` of the HTML element with the `id` `"block-1"`:
```css
#block-1 {
color: red;
}
```
#### How to submit
This exercise must be submited as a JS file, thankfully, javascript allows you to write `CSS` !
Here is how you would submit the `CSS` sample from above in the editor:
```js
document.documentElement.innerHTML = `
hello
`
```
