Pixart

For this assignment you'll be creating a Javascript painting app. When you're done, it should display this functionality.

Use the starter code and commit each step of the exercise.

Prerequisites

  • HTML, CSS & JavaScript
  • The DOM & DOM Selectors
  • Event Listeners & Event Handlers

Instructions

  1. Fork and clone this repository.
  2. Fullfill the listed requirements.
  3. Make a pull request to turn your work in.

Commit 1

  • When I click the "Set Color" button, it should change the color of the "brush" box to the color I specify in the input field.
  • You can use document.querySelector (or another document method) to select the element, then add an event listener.

HINT: You will notice that the page refreshes whenever you click the button. You need to prevent this from happening using a method you have not used before. Google "javascript event prevent default". You can also reference this portion of the Events & Callbacks lesson plan.

Commit 2

  • The same thing should happen when I press the enter key from inside the input field

Commit 3

  • Create 20 divs of the "square" class and append them to the body
    • Hint: use .appendChild()

Commit 4

  • Add functionality so that when I click on each "square", it changes the color of that individual square to "green"
    • Hint: either add the event listener while creating the squares, or listen for events on the body element

Commit 5

  • Modify your code so that when I click on each "square", it changes to the color I set using my input instead of "green" every time.

Commit 6

  • Modify the CSS so that the "square" class has a height and width of 10px and a margin of 0.
  • Modify your code so that you are creating 8000 divs instead of 20.
  • Change the event that changes your box colors from 'click' to 'mouseover'
  • Paint a picture!

Bonus

  • Add a color swatch. You should have 3 boxes with the most recent 3 colors used. When you click on each of those boxes, it should set the current brush color back to that color.
  • Refactor your code using event propogation.
