So in summery: Large text is great as title text try to work in a few keywords for SEO but don't write a whole page in 28 font or your visitors might not be too happy.
所以总结一下：大的字体做为标题是很好的，试着给SEO一些更加精简有效的关键字，但也不要全篇的都是28号字，不然访客会很不开心的哦。
Also, a font size below about 10px is probably too small for anyone to read in large amounts.
还有，10像素以下的尺寸对大量阅读的人来说太小了。
