Example

Before and after

This kind of selector is hard to reuse. It depends on too much page structure.

A class on the actual component is easier to read and move.

/* Hard to maintain */
main section div form input[type="email"] {
  padding: 12px;
}

/* Easier to maintain */
.form-field {
  padding: 0.75rem;
}
