InvalidArgumentException.
| Exception | Thrown when |
|---|---|
InvalidPolicy | a policy is asked to allow a property or function that is never allowed, or is given a maximum length or depth below 1 |
NestingTooDeep | Syntax\Parser, used on its own, meets blocks and functions nested deeper than its limit |
The messages name what is wrong:
The property "behavior" can run code or load a binding; it is never allowed.
The function "image-set()" can run code or load a resource; it is never allowed.
The maximum depth must be at least 1; got 0.
The CSS nests blocks and functions deeper than 32 levels, on line 4.CssSanitizer never throws on the CSS it reads: it catches NestingTooDeep and returns a TooDeep removal.
