Glyphs designed for ruby are optimized for those small point sizes. It is possible on some screen resolutions we might want to make it a bit bigger but as screen resolution gets higher I think it makes more sense to stick to 50% following the standard in printing.</div><div><br></div><div>- kida</div><div><br></div><div><div>On 2010/11/03, at 12:05, Eric Mader wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><br><div><div>On Nov 3, 2010, at 8:56 AM, David Hyatt wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">WebKit enforces a minimum font size of 9px when no explicit font size is specified.

The website I was using has the line height set too tight for correct display this way, and I just wanted to try a smaller size to see if it looked better. OTOH, that site loads a style sheet that overrides the ruby text font-size to 6pt, so I can't easily override it, and its' probably displaying as 9pt anyhow.</div><div><br></div><div><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>dave</div><div>(<a href="mailto:hyatt@apple.com">hyatt@apple.com</a>)</div></div></blockquote><div><br></div>Regards,</div><div>Eric</div><div><br><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><div><div><div>On Nov 3, 2010, at 1:20 PM, Eric Mader wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi,<div><br></div><div>As part of my work on ruby text enhancements, I'm implementing the option of not counting the height of the ruby text in the overall line height.
