Unknown Property 'text-decoration-thickness'

enuddleyarbl · 08-12-2022, 03:50 PM

In trying to fix a problem with the thickness of the strikethrough line in "text-decoration: line-through" (via css classes, styles, <del> or <s>), I ran across posts saying to set the thickness of the line with text-decoration-thickness:

https://developer.mozilla.org/en-US/...tion-thickness

When I try in Calibre's editor (Calibre 6.3 and previous versions), it doesn't seem to do anything and when I run Calibre's Check Book, it gives me the error:

Unknown Property 'text-decoration-thickness'

for my stylesheet.css Running epubCheck has no problem with it. I assume Calibre should handle that property, so I'm reporting it here.

EDIT: Sorry. In 6.3, it looks like the text preview in the editor DOES reflect the thickness setting (it didn't in earlier version). But, Check Book is still giving the error.

It doesn't matter. KePub won't respect this CSS setting. So there's no point to use it.

text-decoration-thickness is from CSS 4 its not supported in anything other than browser based viewers, and relatively up to date ones at that, like the calibre viewer.
