Although the best width may by 1024 you'll have to adjust height for account for various browser settings (navigation toolbar, bookmark toolbar, status toolbar, etc) and account for taskbar settings. It'll quickly drop the 768 down to around 550.
无论您的目标浏览器大小如何,请确保包括浏览器工具栏、状态栏和滚动条的空间,如上所示。在工具栏和状态栏中,Internet Explorer (IME)常常有超过100px 的垂直空间。通常,如果我拍摄1024 x 768,我会尝试创建一个约960-980像素宽和600像素高的设计是安全的。这样,如果需要的话,你可以适应滚动和一些漂亮的空白(如果设计需要的话)。我强烈推荐 YUI 网格用于需要针对特定大小的实例:
1024 = ~960. Accounting for scrollbars, window edges, etc means the real width of a 1024x768 screen is 大约960像素. Some tools are based on a 体积稍小,大约940. This is the default container width in Bootstrap.
As far as 'above the fold', I just have to caution against using any such concept on the web. Horizontal scrolling can and should be avoided, but vertical scrolling is something you cannot 100% avoid. All I can tell you is that on a 1024x768 display (at least 95% of users have that or higher) you should be OK with a fixed 600px high block. But there are many different display formats out there, the browser chrome can take up a lot of room, and not everybody maximizes the browser window.
