Adding a semicolon after the last declaration of a rule is not mandatory. But omitting this semicolon could lead to unexpected issues.

## Noncompliant Code Example

Let's take the following piece of code as an example:

    .foo {
      background-color: red;
      color: green             /* Noncompliant */
    }

Then, add some properties:

    .foo {
      background-color: red;
      color: green             /* Noncompliant */
      width: 30px;
    }

Now, you might waste time figuring out why the width declaration isn't working. Even worse, you can even fail noticing that it's not working.

## Compliant Solution

    .foo {
      background-color: red;
      color: green;
      width: 30px;
    }
