>> Current Firefox behavior -- which was designed to harmonize with host platform behavior -- uses an angle between 11.3deg and 16.7deg > Could you clarify which angle is used on which platform? Gecko implements synthetic-oblique using a "skew factor" defined in https://searchfox.org/mozilla-central/rev/003262ae12ce937950ffb8d3b0fa520d1cc38bff/gfx/thebes/gfxFont.h#61-69: ``` // The skew factor used for synthetic-italic [oblique] fonts; // we use a platform-dependent value to harmonize with the platform's own APIs. #ifdef XP_WIN #define OBLIQUE_SKEW_FACTOR 0.3f #elif defined(MOZ_WIDGET_GTK) #define OBLIQUE_SKEW_FACTOR 0.2f #else #define OBLIQUE_SKEW_FACTOR 0.25f #endif ``` where this "skew" is the tangent of the resulting oblique angle. So we have (approximately) 16.7° on Windows, 11.3° on Linux, and 14° on macOS. -- GitHub Notification of comment by jfkthame Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/2295#issuecomment-376252376 using your GitHub account
