The following table provides user agent's guideline for the absolute-size scaling factor and their mapping to XHTML heading and absolute font-sizes. The 'medium' value is used as the reference middle value. The user agent may fine tune these values for different fonts or different types of display devices.
CSS absolute-size values xx-small x-small small medium large x-large xx-large scaling factor 3/5 3/4 8/9 1 6/5 3/2 2/1 3/1 XHTML headings h6 h5 h4 h3 h2 h1 XHTML font sizes 1 2 3 4 5 6 7 Note 1. To preserve readability, an UA applying these guidelines should nevertheless avoid creating font-size resulting in less than 9 pixels per EM unit on a computer display .
Note 2. In CSS1, the suggested scaling factor between adjacent indexes was 1.5 which user experience proved to be too large. In CSS2, the suggested scaling factor for computer screen between adjacent indexes was 1.2 which still created issues for the small sizes. The new scaling factor varies between each index to provide a better readability.
遂に Third Edition (TE?) がキター。まだ PER ですが、SE の Errata を反映しただけなのですぐ REC になるでしょう。レビュー期間は12月1日まで。
そういえば、PER が出たのは(多分)今回が初めてですね。
……ついでに Namespaces in XML (Errata) の SE も作ってくれないかなぁ。
