Is Leaving Out Semicolons in CSS Good Practice?

Leaving Out the Last Semicolon in CSS

Is it Good Practice?

Manually excluding semicolons is discouraged due to its potential for errors. Adding new styles without a semicolon may result in previous declarations not working as intended.

Load Time Performance

Removing semicolons can save bytes, particularly for large style sheets. However, using a CSS compressor is a more practical approach to optimizing performance.

Browser Compatibility

CSS browsers correctly implement this part of the specification. A declaration in CSS2 consists of a property name followed by a colon and a value, and multiple declarations for the same selector can be separated by semicolons. However, the semicolon is not required to terminate a declaration.

JavaScript Last Function

This rule does not apply to JavaScript, which has a different specification.
