CSS Structure and Formatting of a CSS Rule
Remarks
For ease of readability, keep all declarations indented one level from their selector, and the closing curly brace on its own line. Add a single space after selectors and colons, and always place a semicolon after the final declaration.
Good
p {
color: maroon;
font-size: 16px;
}
Bad
p{
color: maroon;
font-size:16px }
One-Liner
If there are only one or two declarations, you might get away with this one. Not recommended for most cases. Always be consistent when possible.
p { color: maroon; font-size: 16px; }
