In express/examples/auth/views/head.ejs at line 13, CSS style for .error class' color attribute is missing a semicolon.

.error { color: red }

The code does not break as the missing semicolon is at the end of the last declaration in the block.

However, for consistency and best practice, a semicolon must be included, even for the last declaration.

Fix

The process for bug fixing is:

• We will insert a semicolon

.error { color: red; }
