+## Build brick and break
+
+### Instructions
+
+Today, your mission is to build a 3-column brick tower, maintain it and finally break it!
+
+Create a function `build` which will create and display the given amount of bricks passed as argument:
+
+- each brick has to be created and added to the page at a regular interval of time (at least 50ms),
+- each brick will receive a unique `id` property, like following:
+
+```html
+<div id="brick-1"></div>
+```
+
+- each brick in the middle column has to be set with the custom attribute `foundation` receiving the value `true`
+
+Each one of the two emojis in the top-right corner fires a function on click:
+
+- 🔨 triggers the function `repair`
+- 🧨 triggers the function `destroy`
+
+Write the body of the `repair` function, which receives any number of `ids`, and for each `id`, retrieves the HTML element and set a custom attribute `repaired` set to `in progress` if it is a brick situated in the middle column, and `true` if not.
+
+Write the body of the `destroy` function, which removes the current last brick in the tower.

+## Fifty shades of cold
+
+### Instructions
+
+You've been asked to freshen a webpage atmosphere by displaying shades of cold colors.
+
+Check the `colors` array provided in the data file below.
+
+- Create a `<style>` tag in the `<head>` tag and generate, for each color of `colors`, a class setting the `background` attribute and taking the color as value, like following:
+
+```css
+.indianred {
+  background: indianred;
+}
+```
+
+- Create a `<div>` for each color of the `colors` array whose name contains `aqua`, `blue`, `turquoise`, `green`, `cyan`, `navy` or `purple`.\
+  Each `<div>` must have the corresponding generated class and display the name of the color, like following:
+
+```html
+<div class="indianred">indianred</div>
+```
+
+- The function `choseShade` is triggered when clicking on a `div`.\
+  Write the body of this function, which receives the shade of the clicked element as argument, and replaces all the other elements class by the chosen shade.
+
+### Notions
+
+- [`head`](https://developer.mozilla.org/en-US/docs/Web/API/Document/head) / [style tag](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/style)
+- [`className`](https://developer.mozilla.org/en-US/docs/Web/API/Element/className)
+- [`classList`](https://developer.mozilla.org/en-US/docs/Web/API/Element/classList): `contains()`, `replace()`
+
+### Provided files
+
+- Import the `colors` from the data file: [data.js](./data.js)
+
+### Expected result
+
+You can see an example of the expected result [here](https://youtu.be/a-3JDEvW-Qg)

+## Get them all
+
+### Instructions
+
+You've been attributed the task to find the main architect of the Tower of Pisa before he achieves his plans, avoiding us nowadays all those lame pictures of people pretending to stop it from falling.
+
+You arrived at the architects' chamber to find him, but all you have in front of you is a bunch of unknown people.\
+Step by step, with the little information you have, gather information and figure out by elimination who he is.
+
+On top of the webpage, each of the four buttons fires a function which has to return an array containing 2 entries: the targetted people, and the others eliminated at that step (the ones previously eliminated mustn't be included).
+
+- Write the body of the `getArchitects` function, which targets the architects, all corresponding to a `<a>` tag.
+
+- Write the body of the `getClassical` function, which targets the architects belonging to the `classical` class.
+
+- Write the body of the `getActive` function, which targets the classical architects who are `active` in their class.
+
+- Write the body of the `getBonannoPisano` function, which targets the architect you're looking for, whose `id` is `BonannoPisano`.
+
+### Notions

+## Gossip grid
+
+### Instructions
+
+Good information is the pillar of society, that's why you've decided to dedicate your time to reveal the powerful truth to the world and deliver essential and strong news: you're launching a gossip grid.
+
+Create the function `grid` which displays all the `gossips`, provided in the data file below, as cards on a grid, and allows the user to:
+
+- add a new gossip to the list
+- customize the width, font size and background of each card with `range` inputs.
+
+### Notions
+
+- [Inputs](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input): [`text`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/text), [`range`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/range)
+
+### Provided files
+
+- Import the `gossips` from the data file: [data.js](./data.js)
+
+### Expected result
+
+You can see an example of the expected result [here](https://youtu.be/nbR2eHBqTxU)

+## Harder, bigger, bolder, stronger
+
+### Instructions
+
+Being stuck at home, bored, desperate and coming up with a lot of weird ideas, a friend asks you to develop a tool to measure his ocular skills: one of those [Monoyer charts](https://en.wikipedia.org/wiki/Monoyer_chart) that ophthalmologists use.
+
+Generate a board where each new letter is harder, bigger, bolder and stronger!
+
+Create the function `generateLetters` which creates 100 `div`, each containing a letter randomly picked through the alphabet, and whose style properties have to be increased:
+
+- `font-size` has to grow from `20` to at least `100` pixels
+- `font-weigth` has to be `300` for the first third of the letters, `400` for the second third, and `600` for the last third
+
+### Notions
+
+- [`style`](https://developer.mozilla.org/en-US/docs/Web/API/ElementCSSInlineStyle/style)
+- [`textContent`](https://developer.mozilla.org/en-US/docs/Web/API/Node/textContent)

+## Keycodes symphony
+
+### Instructions
+
+Like an inspired Beethoven who's going to write his Moonlight Sonata, you're about to compose a colourful symphony of letters with your keyboard.
+
+Export the function `compose`:
+
+- Make it fire every time a key is pressed
+- Create a new `note`, which has a background color generated using its `keyCode`, and displays the corresponding letter pressed
+- If the pressed key is the `Delete` one, delete the last note
+- If the pressed key is the `Escape` one, clear all the notes
+
+### Notions
+
+- [Keyboard event](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent): [`keydown`](https://developer.mozilla.org/en-US/docs/Web/API/Document/keydown_event), [`key`](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key)

+## Mouse trap
+
+### Instructions
+
+Develop a trap to capture the elements when the mouse is getting too close to the center of the page!
+
+- Create a function `createCircle`: make it fire on every click on the page, and create a white circle at the position of the mouse on the screen
+
+- Create a function `moveCircle`: make it fire when the mouse moves, and get the last circle created and makes it move along with the mouse
+
+- Set a box in the center of the page ; when a circle is inside that box, it has to be purple ; once a circle enters the box, it is trapped inside and cannot go out of it anymore.
+
+### Notions
+
+- [`addEventListener()`](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener): `click`, `mousemove`

+
+- displays the `hue` value in text
+- displays the `luminosity` value in text
+- displays the full `hsl` value in text
+- copies that value in the clipboard on click
+- displays two lines, for X and Y axis, following the cursor

+## Pimp my style
+
+### Instructions
+
+Check out that button on the HTML page:
+
+```html
+<div class="button">pimp my style</div>
+```
+
+For now, it's only a lonely, basic and sad element ; let's pimp it up!
+
+On each click on the page, a function `pimp` is triggered.
+Write the body of that function so that the button's class is altered:
+
+- Add in order the next class of the `styles` array provided in the data file below
+- When the end of the array is reached, remove backwards each class
+- Toggle the class 'unpimp' when removing classes
+
+```
+Example for a `styles` array with only 3 classes:
+
+Page load --> <div class="button"></div>
+
+...adding
+Click 1 --> <div class="button one"></div>
+Click 2 --> <div class="button one two"></div>
+
+...toggling `unpimp`
+Click 3 --> <div class="button one two three unpimp"></div>
+
+...and removing backwards
+Click 4 --> <div class="button one two unpimp"></div>
+Click 5 --> <div class="button one unpimp"></div>
+Click 6 --> <div class="button"></div>
+```
+
+### Notions
+
+- [`classList`](https://developer.mozilla.org/en-US/docs/Web/API/Element/classList): `add()`, `remove()`, `toggle()`
+
+### Provided files
+
+- Use this CSS file: [https://mariemalarme.github.io/dom-js/assets/style/pimp-my-style.css](https://mariemalarme.github.io/dom-js/assets/style/pimp-my-style.css)
+- Import the `styles` from the data file: [https://mariemalarme.github.io/dom-js/assets/data/pimp-my-style.js](https://mariemalarme.github.io/dom-js/assets/data/pimp-my-style.js)

+## Where do we go?
+
+### Instructions
+
+Tired of staying home for too long, you decide to develop a page to index ideas for your next travel destinations, so that next time you'll ask yourself 'Where do we go?', you won't need to get lost for 3 hours!
+
+Create a page which displays the list of `places` provided in the data file below:
+
+- sort the `places` from the Northest to the Southest
+- display a fullscreen-size image for each place ; use the images hosted here: `https://github.com/MarieMalarme/dom-js/tree/master/assets/images`, also available as Github Pages here `https://mariemalarme.github.io/dom-js/assets/images/locationName.jpg`
+- display a location indicator, displaying the `name` and the `coordinates` of the current place featured in the image, using the corresponding `color` as text color, which updates on scroll when another image is reached
+- display a compass indicating the latitude direction ; North if the user is scrolling up, South if he's scrolling down
+- when clicking on the page, open a link redirecting to the Google Maps' coordinates of the place currently displayed.
+
+### Notions
+
+- [Wheel event](https://developer.mozilla.org/en-US/docs/Web/API/Element/wheel_event): [`deltaY`](https://developer.mozilla.org/en-US/docs/Web/API/WheelEvent/deltaY)
+- [`window`](https://developer.mozilla.org/en-US/docs/Web/API/Window): [`innerHeight`](https://developer.mozilla.org/en-US/docs/Web/API/Window/innerHeight), [`scrollY`](https://developer.mozilla.org/en-US/docs/Web/API/Window/scrollY), [`open()`](https://developer.mozilla.org/en-US/docs/Web/API/Window/open)
+
+### Provided files
+
+- Import the `places` from the data file: [https://mariemalarme.github.io/dom-js/assets/data/where-do-we-go.js](https://mariemalarme.github.io/dom-js/assets/data/where-do-we-go.js)
