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.
Note: on the production platform, this file will be compressed and comments will be removed. Consequently, don't hesitate to put as many comments as necessary.
Important: ALL the CSS directives for your game must be included in this CSS file. You can't create additional CSS files and import them.
