Game interface stylesheet: yourgamename.css

This is the CSS stylesheet of your game User Interface.

Styles defined on this file will be applied to the HTML elements you define in your HTML template (yourgame_yourgame.tpl), and to HTML elements you create dynamically with Javascript.

Usually, you are using CSS to:

1°) define the overall layout of your game (ex: place the board on the top left, place player's hand beside, place the deck on the right, ...).

2°) create your CSS-sprites: All images of your games should be gathered into a small number of image files. Then, using background-image and background-position CSS properties, you create HTML blocks that can display these images correctly.

Example:

    Example of CSS sprites (a black token and a white token, 20x20px each, embedded in the same "tokens.png" 40x20px image):

    .white_token {
        background-image: url('../../img/emptygame/tokens.png');
        background-position: 0px 0px;
    }
    .black_token {
        background-image: url('../../img/emptygame/tokens.png');
        background-position: -20px 0px;
    }
    .token {
        width: 20px;
        height: 20px;
        background-repeat: none;
    }

3°) ... anything else:

It is really easy to add and remove CSS classes dynamically from your Javascript with dojo.addClass and dojo.removeClass. It is also easy to check if an element has a class (dojo.hasClass) or to get all elements with a specific class (dojo.query).

This is why, very often, using CSS classes for the logic of your user interface allow you to do complex thing easily.
