A simple demo demonstrating the power of pure HTML5 and CSS3 by implementing the logical OR function. In this demo register `A`

and `B`

can be set to the equivalent binary that represents an 8-bit integer. After processing, the `R`

register will contain the equivalent binary of the integer equal to `A ∨ B`

(`A OR B`

).

- Set both register
`A`

and register`B`

to the binary representation of two binary integers. - Press the
`TAB`

key to go to the first bit in`R`

that needs to be changed. - Press
`SPACE`

to set that bit. - Repeat steps 2-3 until none of the bits in
`R`

are either yellow, or magenta.
