Label

- for property of label element is useful for pointing to input element using its id
  for eg:
  ```html
  <input type="file" id="actual-btn"/>

  <!--our custom file upload button-->
  <label for="actual-btn">Choose File</label>
  ``` 
 
  Now when the user clicks on **label** will ask for uploading file too just like we click on **input**
