-### Select & style
+## Select & style
 
-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](https://developer.mozilla.org/en-US/docs/Web/CSS).
-Create a CSS file, [link it](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/link#including_a_stylesheet) to your `select-and-style.html`, and:
+### Instructions
 
-- target all the elements with the [universal selector](https://developer.mozilla.org/en-US/docs/Web/CSS/Universal_selectors) and style them with a `margin` of 0, `box-sizing` to "border-box" and an `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](https://developer.mozilla.org/en-US/docs/Web/CSS/Type_selectors), and style it with a `padding` of 20 pixels, a `width` of 100% and a `height` of "calc(100% / 3)" (one third of the `body` height)
-- target each following element with the [`id` selector](https://developer.mozilla.org/en-US/docs/Web/CSS/ID_selectors), using the `id` you defined earlier for each section, and style it:
