This is a very simple short notes on how to remove the extra line from a copy and paste from vs code.

white-space: pre;

Replace all with  white-space: pre;

Example:

ion-menu ion-content {
  --padding-top: 20px;
  --padding-bottom: 20px;
  --background: var(--ion-item-background, var(--ion-background-color, #fff));
}
/* Remove background transitions for switching themes */
ion-menu ion-item {
  --transition: none;
}

 

Example Cleaned by removed all white-space: pre;

ion-menu ion-content {
  --padding-top: 20px;
  --padding-bottom: 20px;
  --background: var(--ion-item-background, var(--ion-background-color, #fff));
}
/* Remove background transitions for switching themes */
ion-menu ion-item {
  --transition: none;
}
