+# `singleLineTopLevelDeclarations`
+
+Control whether to force to format all top-level declarations on a single line.
+
+When this option is `true`, trailing semicolons are removed.
+
+Most of the time, you don't need to set this option, because declarations at top level are invalid,
+but if you're formatting HTML's `style` attribute, you may want to set this to `true`.
+
+Default option is `false`.
+
+## Example for `false`
