Should I put input elements inside a label element?

Question

Is there a best practice concerning the nesting of label and input HTML elements?

classic way:

Answer 1

From w3:

The label itself may be positioned before, after or around the associated control.

---

Last Name

or

Last Name

or

   
   Last Name

Note that the third technique cannot be used when a table is being used for layout, with the label in one cell and its associated form field in another cell.

Either one is valid. I like to use either the first or second example, as it gives you more style control.
