merge-covered-key

An sz key the build removed because a later key in the same object covers it.

• csszyx check reports it in its merge-covered-key pass.
• It is printed to the console. A production browser bundle leaves it out.

Message

A name in angle brackets is a value the message fills in.

[csszyx] merge-covered-key: The build removes `<className>`, written as `<key>`, because a later key in the same sz object sets every property it sets.
  help: delete `<key>` from the object; to keep every covered class, set `build.mergeCoveredClasses: false` in the plugin options.

Level

Default: info under recommended, warn under atomic. Set it in csszyx.config: rules: { 'merge-covered-key': 'warn' }.

The level sets how the build and csszyx check report it. It does not change a console line, and it does not stop a thrown error.

Arguments

The values this diagnostic names.
