有效的CSS / HTML的要点是什么？ [英] What's the point of valid CSS/HTML?

问题描述

如果我在大多数主要浏览器中测试了我的网页，为什么我需要维护验证的代码？我想使用box-shadows和角半径，如果它们在WebKit浏览器和Firefox支持。我不在乎他们不在Internet Explorer上显示。但是我通过不包括图像来保持我的HTTP请求。

If I've tested my pages in most major browsers, why would I need to maintain a validated code? I want to use box-shadows and corner radius if they're supported in WebKit browsers and Firefox. I don't care if they don't show up on Internet Explorer. But I keep my HTTP requests down by not including images instead.

有效的代码有优势吗？在SEO或其他方面？

Are there are advantages to valid code? In SEO or otherwise?
