is there any way in java, html, css, etc. for people to bet on things, like a way to put a product on my website and people to put X dollers on a product and nameless2 can bet X dollers more than nameless1
HTML5 probably, Java definitely, css I've never even looked at it. Basically you would create and object to hold the information for the item and have a variable inside the object for the current price. The user can then modify the price with a GUI made to modify the price through method calls.
