# Pixel Art Maker
|
|
|
|
In this exercise, you'll create your own pixel art maker which will allow a user to choose colors from a palette and then paint pixel art. The interface is completely up to you, but it could look something like this.
|
|
|
|
|
|
|
|
More specifically, your pixel art maker should allow a user to do the following.
|
|
|
|
1. Start with a blank canvas of pixels.
|
|
1. Select a brush color from a palette of colors.
|
|
1. Paint the pixels on the canvas using the brush color.
|
|
1. Repeat step 2.
|
|
|
|
Here's a development workflow that we recommend you use.
|
|
|
|
1. Fork and clone this repository.
|
|
1. Create a small, 2x2 grid canvas made up of white, square `div` tags with a border.
|
|
1. Add an event listener to each `div` so when clicked the background turns red.
|
|
1. Create a small palette of two colors (e.g. red and blue) below the canvas using more `div` tags.
|
|
1. Add an event listener to these `div` tags so when clicked the brush color is saved.
|
|
1. Expand the dimensions of the pixel canvas.
|
|
1. Expand the palette with more colors. (i.e. red, orange, yellow, green, blue, purple, brown, gray, black, white, etc.)
|
|
1. Expand the palette with a brush color indicator.
|
|
1. Improve the look and feel of the canvas and color palette. Be careful not to break your program's behavior!

|
|
|
|
### Bonus 1
|
|
|
|
Improve the mouse so it behaves like a real paintbrush. In other words, allow the user to paint by clicking and dragging across the canvas. For this, you'll need a combination of the `mousedown`, `mouseenter`, and `mouseup` events.
|
|
|
|
**TIP:** The [`mouseenter` event](https://developer.mozilla.org/en-US/docs/Web/Events/mouseenter) doesn't bubble up the DOM tree.
|
|
|
|
### Bonus 2
|
|
|
|
Add a color picker which allows the user to select any brush color using the [`<input type="color">` tag](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/color) and the [`change` event](https://developer.mozilla.org/en-US/docs/Web/Events/change).
|
|
|
|
### Bonus 3
|
|
|
|
Research [LocalStorage](https://developer.mozilla.org/en-US/docs/Web/API/Storage/LocalStorage) and make a way to Save and Load a drawing. Research [JSON.stringify](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) and [JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse) as a way to put the drawing into LocalStorage.
|
|
|
|
### Bonus 4
|
|
|
|
Create a fill tool that will [flood fill](https://en.wikipedia.org/wiki/Flood_fill) boundaries with a chosen paint color.
|

|
|
|
Read over the following articles to learn how to deploy this web site to Surge.

|
- [Remembering a domain](http://surge.sh/help/remembering-a-domain)
|
|
|
|
A good domain name for this project is `USERNAME-pixel-art-maker.surge.sh` where `USERNAME` is your GitHub username in all **lowercase** letters. Once deployed and everything works as you expect, copy your Surge URL and paste it at the top of your GitHub repository's page.
