This is the expected behavior for CSS code blocks. It uses the built-in CSS syntax highlighting in VSCode. Since CSS itself does not support inline classes, you can see that .animation-title is not correctly colored.

For lang="postcss", since VSCode does not have built-in PostCSS syntax highlighting, it will use the syntax highlighting provided by the PostCSS extension you have installed. The actual behavior depends on the PostCSS extension you have installed.
