SW15001: CSS offset exceeds source coordinates

A stylesheet is too large for the compiler's source positions.

This error occurs when a stylesheet is so large that a position in it does not fit in the compiler’s 32-bit source positions, which allow about 4 GB. Such a stylesheet is almost always generated by mistake.

How to fix

  • Find the tool or plugin that generates the stylesheet, and limit its output.
  • Split the stylesheet into several files.

If the stylesheet has a normal size, report the error as a bug with the input sizes.
