Site has no styling
Problem: After upgrading from sbt-microsites 0.x to 1.x, my microsite has no
styling at all. The
target/site/css/ directory is not being generated.
Solution: You probably have the wrong version of Jekyll installed. sbt-microsites 0.x had a dependency on Jekyll 3.x, but sbt-microsites 1.x requires Jekyll 4.0.0 or newer.
