I've noticed that, in programming, a semi-colon is used after each command to tell the program to STOP.
Why, when calling a CSS selector, do we not use a semi-colon?
In other words, why is it like this: p {}
rather than: p {};

p { /* { open the Code Block*/
color: royalblue; /*Semi-colon end this line of code so we can jump to the next line*/
background-color: black /*Now in the last line we don't need another semicolon because there is nothing else to put below but is always good to put the semicolon at the end of any value so when we're modifying something we don't forget that we need to end the line before starting a new one or you know a little semicolon can cause a big headache*/
} /*Close the Code Block*/

The semicolon ends a statement, much like the period(.) does in English for a sentence. The code block groups related statements together, much like how we group related sentences in a paragraph.

Treehouse Project ReviewerCSS isn't actually a programming language, it is a stylesheet. I saw someone once say that the difference is that CSS (and HTML) describe presentation, where as a programming language describes function.
