Is Omitting the Final Semicolon in CSS Blocks Ever a Good Idea?

Omitting the Final Semicolon in CSS Blocks

Developers often ponder the consequences of omitting the final semicolon from CSS blocks. This practice raises several questions:

• Is it Ethical?
  No. Neglecting semicolons can lead to accidental omissions and confusion, particularly in collaborative work environments.
• Enhanced Loading Speed?
  Yes, each omitted semicolon saves bytes. While the impact may be negligible for smaller stylesheets, CSS compressors like the YUI Compressor automate this optimization, saving time and effort.
• Browser Compatibility Concerns?
  No. Browsers correctly implement the CSS2 specification, which indicates that multiple declarations for the same selector can be separated by semicolons but do not require semicolons to terminate them.
• Applicable to JavaScript?
  No. JavaScript follows distinct specifications and should not follow the practice of omitting the final semicolon from function definitions, which has been discussed extensively on Stack Overflow.
