Comments in code examples often rely on exact column alignment, e.g. for ASCII-art. This alignment often relies on both code and comment characters having exactly the same width. Setting `font-style: italic` seems to break these invariants with common monospace fonts used by browsers. This may be due to font synthesis when the monospace font does not have a native italic variant. E.g., see these code examples when using the `ayu` theme: - https://doc.rust-lang.org/1.90.0/reference/types/closure.html#r-type.closure.drop-order - https://doc.rust-lang.org/1.90.0/reference/types/impl-trait.html#r-type.impl-trait.generic-capture.precise.use It seems more important to have correct alignment than to style these elements in italics, so let's drop the italic styling. One alternative would be to set `font-synthesis: none` instead. This would prevent font synthesis-related misalignment while still rendering italics when a font supports italics natively. This might correct the alignment issue, but ASCII-art in comments often wants vertical bars to actually be vertical, so it still seems better to just turn off italics entirely. A more minimal change might be to only drop this from comments and not from `hljs-quote`, but it seems the styling for these classes are usually kept in sync, so we preserve that here. |
