- Create the divs using JavaScript. Don’t try making them by hand with copy and pasting in your HTML file!
- It’s best to put your grid squares inside another “container” div (which can go directly in your HTML).
- You need make the divs appear as a grid (versus just one on each line). This is a perfect opportunity to apply what you have learned about flexbox.
- Be careful with borders and margins, as they can adjust the size of the squares!
Set up a “hover” effect so that the grid divs change color when your mouse passes over them, leaving a (pixelated) trail through your grid like a pen would.
- Hint: “Hovering” is what happens when your mouse enters a div and ends when your mouse leaves it. You can set up event listeners for either of those events as a starting point.
- There are multiple ways to change the color of the divs, including: - adding a new class to the div. - changing the div’s background color using JavaScript.
Add a button to the top of the screen that will send the user a popup asking for the number of squares per side for the new grid. Once entered, the existing grid should be removed and a new grid should be generated in the same total space as before (e.g. 960px wide) so that you’ve got a new sketch pad.
Tip: Set the limit for the user input to a maximum of 100. A larger number of squares results in more computer resources being used, potentially causing delays, freezing, or crashing that we want to prevent.
- Research button tags in HTML and how you can make a JavaScript function run when one is clicked.
- Also check out prompts.
- You should be able to enter 64 and have a brand new 64x64 grid pop up without changing the total amount of pixels used.
- Instead of just changing the color of a square from black to white (for example), have each pass through with the mouse change it to a completely random RGB value. Then try having each pass just add another 10% of black to it so that only after 10 passes is the square completely black.
