Draw a black rectangle in the center of a white canvas.

Use the slider from jQuery Mobile to alter the RGB values of a rectangle to allow the user to select a color of a rectangle. Do not use the color picker tool, I want you to write you own way to select a color manually by RGB values). If can additionally use the color picker if you wish.

Have a slider that makes the rectangel larger/smaller.

Use a radio button, to toggle the color of the background/rectangle.

Have a checkbox that will hide the rectangle on the screen.

Have a reset button to put things back to the begining values.

This is what I have so far!

Choose color:

Red

Blue

Green
