Fix steps

  1. 1 Count opening and closing braces near the failing selector.
  2. 2 Close the active rule before the next selector.
  3. 3 Format CSS to verify rule boundaries.

Invalid CSS

The .button rule never closes.

.button {
  color: white;
.card { padding: 1rem; }

Output

Missing closing brace

Fixed CSS

Close the first rule before starting the next selector.

.button {
  color: white;
}
.card { padding: 1rem; }

Output

Valid CSS
