Another one just for the fun of it, a simple CSS ONLY calculator for kids.
Start by selecting a number from the first column, your selection will have a dark gray border. Then move horizontally to the second column and select either PLUS, MINUS, MULTIPLY or DIVIDE, again your selection will have a dark gray border. Move horizontally to the third column and select your next number. Finally move horizontally to the fourth column and move up or down to the EQUALS sign and your answer will be displayed to the right of the EQUALS sign (to 2 decimal places).
Remember please that this is just for fun and was a break from the more 'useful' CSS demonstrations. But the idea may have other applications where there are 256 different paths to follow from one side of the grid to the other.
Should anyone want to use this on a 'kiddies website' then please let me know.
Because of all the time and effort spent in producing this demonstration I would ask that you respect my copyright.
