What is iCentral > > i* corresponds to ideographic-* defined in https://drafts.csswg.org/css-inline-3/#baseline-types Thank you, so: * iTop = ideographic-over * iBottom = ideographic-under * iCenter = central ? `central` is defined as "halfway between the ideographic-under and ideographic-over baselines", so it will never be defined without iTop and iBottom, correct? > (Please note this is not a metric used for CSS layout. This is just for this particular Canvas API. See https://html.spec.whatwg.org/multipage/canvas.html#dom-textmetrics-fontboundingboxascent ) Thank you, yes, I think we're in sync. `emHeightAscent` and `emHeightDescent`, not `fontBoundingBoxAscent` and `fontBoundingBoxDescent`, correct? Fonts have horizontal and vertical metrics. Which metrics do we want? Maybe we suggest HTML Canvas to add horizontal and vertical metrics? -- GitHub Notification of comment by kojiishi Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/5312#issuecomment-664872120 using your GitHub account
