响应“地球一小时”号召 天府熊猫塔熄灯一小时
百度 二是截至去年年底，国四环保标准的车型（基本上2009年之后的车型都为国四环保标准）已经可以迁往全国80%以上的地级市市场，因此这项政策本身对北京二手车市场的影响不大。S5 is a slide show format based entirely on XHTML, CSS, and JavaScript. With one file, you can run a complete slide show and have a printer-friendly version as well. The markup used for the slides is very simple, highly semantic, and completely accessible. Anyone with even a smidgen of familiarity with HTML or XHTML can look at the markup and figure out how to adapt it to their particular needs. Anyone familiar with CSS can create their own slide show theme. It's totally simple, and it's totally standards-driven.
If you'd like to see S5 in action, go ahead and run through the introductory slide show (also available as a 186KB ZIP archive, the size of which is due to the presence of several images in the slide show). Feel free to try any of the features. For example, you can hit the space bar to advance to the next slide. Or use the right arrow, the down arrow, hit Return... any of these will work. The other features will be explained in, or else demonstrated by, the slide show itself.
If you like the general idea of S5 but don't like the theme used for the introductory slide show, then fear not: there are already a number of themes available, and you can of course always create your own.
If you have a hankerin' to know more about how this system works, exactly, we have a few resources that might help.
- A Basic Primer in Using S5 — pretty much what it sounds like.
- S5 Reference — a full reference describing what markup is required, what is recommended, and what is optional in an S5 presentation file.
- Minimal S5 Structure — a guide to the absolute bare minimum markup used in an S5 slide file.
- S5 File Map — explains what files are where, and what each one does.
- S5 FAQ — it may not answer all your questions, but it will answer the common ones. The uncommon ones you'll have to send in.
