known-failures.md
There are certain edge cases where Prism will fail. There are always such cases in every regex-based syntax highlighter.
However, Prism dares to be open and honest about them. If a failure is listed here, it doesn’t mean it will never be fixed. This is more of a “known bugs” list, just with a certain type of bug.

''Italic with '''bold''' inside''
Some of our themes are not compatible with certain layouts.
Coy's shadows and background might not wrap around the code correctly if combined with float of flexbox layouts.
There are 2 possible workarounds:
The first workaround is setting display: flex-root; for the pre element. This will fix the issue but flex-root has limited browser support.
The second is adding clear: both; to the style of the pre element. This will fix the issue but it will change the way code blocks behave when overlapping with other elements.
