CSS Sprites: Image Slicing’s Kiss of Dea. Back when video games were still fun (we’re talking about the 8-bit glory days here), graphics were a much simpler matter by necessity. Bitmapped 2-dimensional character data and background scenery was individually drawn, much like today’s resurgent pixel art. Hundreds and later thousands of small graphics called sprites were the building blocks for all things visual in a game. Article Continues Below As game complexity increased, techniques developed to manage the multitude of sprites while keeping game play flowing. One variation saw sprites being plugged into a master grid, then later pulled out as needed by code that mapped positions of each individual graphic, and selectively painted them on the screen. And what does this have to do with the web?
Everything old is new again, and though the rise of 3D games has made sprite maps obsolete, the concurrent rise of mobile devices with 2D gaming capabilities have brought them back into vogue. How do CSS Sprites work? On to the HTML. Tables. 17.1 Introduction to tables This chapter defines the processing model for tables in CSS. Part of this processing model is the layout. For the layout, this chapter introduces two algorithms; the first, the fixed table layout algorithm, is well-defined, but the second, the automatic table layout algorithm, is not fully defined by this specification. For the automatic table layout algorithm, some widely deployed implementations have achieved relatively close interoperability. Table layout can be used to represent tabular relationships between data. Authors specify these relationships in the document language and can specify their presentation using CSS 2.1.
In a visual medium, CSS tables can also be used to achieve specific layouts. Authors may specify the visual formatting of a table as a rectangular grid of cells. Example(s): Here is a simple three-row, three-column table described in HTML 4: Note, however, that the borders around the rows overlap where the rows meet. Table element consecutive.

CSS-based liquid layout has proven successful during the reign of 800-pixel to 1024-pixel screens, but as we use a wider range of devices to access the web, we need more powerful and flexible ways of managing layout.
If we want to serve devices whose viewports range from 240 pixels to about 1680 pixels—and with resolution ranging from 72 to 150 pixels per inch—we need a new method. What’s the problem with liquid layouts? #section1 If you create a liquid layout optimized for a maximum width of 1024 pixels—limiting maximum line-lengths for your text to maintain readability— gaps will appear on a wider screens, and your carefully balanced layout will break. On a tiny-screened PDA, your text and images will be compressed into a crowded content sandwich. So why don’t we just define layout and appearance for a series of screen-width ranges, then find a way to match these layouts with the user’s viewport size?
