CSS 文字阴影在网页设计中的应用

C S S不久以前我有一篇文章介绍了 CSS3 鼠标悬停动画,里面简单提过关于 text-shadow, 本文则是详细写 text-shadow. 很遗憾 IE 仍然无缘,IE8 都不行,在这个 IE 特别是 IE6 居高不下的国度怎么办,由它去吧。

Google Goggles

由于刚刚横空出世的 Goggles, 这个 Android 应用系列文章加映一期。Goggles 是 Google 又一个有趣的产品,以前我们只能输入文字搜索,后来 Android 平台上又有了对中英文都有良好识别率的语音搜索,可是如果不知道要搜索的东西叫什么名字,怎么办呢,试试 Goggles, 用手机拍摄它。

当然,并不是随便拍什么都可以识别,其实识别的过程就是从 Google 索引中寻找相似图片,比如著名景点、商标、产品、海报、人脸等,能否获得准确的结果一般取决于类似的图片在网络中是否好找。此外,Goggles 可用于: 阅读全文
