Inline CSS formatting best practices - Two questions

Question

Question #1 - When specifying an inline style in an HTML element, is it necessary to include a trailing semi-colon? For example ...

Answer 1

Question 1: Yes (if you have more than one inline-style specified. Even it's not required for the last one, it's a good practice to append ; after each one).

Quote:

The normal rules of CSS apply inside the style attribute. Each CSS statement must be separated with a semicolon ";" and colons appear between the CSS property and its value.

Question 2: No, but you can add it to be easier to read. For instance, Eclipse formatting automatically adds this space.
