classic way:

    The primary advantage of placing input inside of label is typing efficiency for humans and byte storage for computers.

    @Znarkus said in his comment to the OP,

    One of the big pros of putting the <input /> inside the <label>, is that you can omit for and id: <label>My text <input /></label> in your example. So much nicer!

    Note: In @Znarknus code, another efficiency was included not explicitly stated in the comment. type="text" can also be omitted and input will render a text box by default.

    A side by side comparison of keystrokes and bytes[1].

    31 keystrokes, 31 bytes

    <label>My Text<input /></label>
    

    58 keystrokes, 58 bytes

    <label for="myinput">My Text</label><input id="myinput" />
    

    Otherwise, the snippets are visually equal and they offer the same level of user accessibility. A user can click or tap the label to place the cursor in the text box.

    From w3:

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


    <label for="lastname">Last Name</label>
    <input type="text" id="lastname" />

    or

    <input type="text" id="lastname" />
    <label for="lastname">Last Name</label>

    or

    <label>
       <input type="text" name="lastname" />
       Last Name
    </label>

    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.
