font-weight on EPUB

[Hosun]

Hi,

[Screenshot 1]

On Id, there are font-weight (light, regular, medium, bold).

On EPUB, medium on CONCLUSION.(4) is not presented well (I want to make it thinner than bold).

So, I wrote:

span.medium {font-weight: ;}

[Screenhot 2]

"font-weight: 900" works.

With font-weight: 100, I can't make medium on CONCLUSION.(4) much thinner than bold.

Is there any workaround?

The only font weights that work consistently in EPUB are Regular, Bold, Italic and BoldItalic (by whatever specific names a given font might use). Other weights, whether named (Light, Semibold, Demi, Black, etc.) or numeric, will map to one of those four. I forget the numeric equivalent ranges for those four, off hand, but 100-500 will map to Regular, 600-900 to Bold.

I'd rather go with font-weight: 400.

It makes no difference on Mac.

But it makes difference on iPhone.

Nearly everything in EPUB is reader-dependent. It's likely that no two readers, even the same app on different platforms, will interpret any given document the same way.

But the standard/vanilla readers only intrerpret those four faces.
