HTML - make input field selectable but not changeable

Question

Like the youtube embed text fields. How do you make a text field selectable but not changeable?

Answer 1

<input type="text" value="Some Text" readonly="readonly" />

Answer 2

Another way to achieve this is just to make a div appear like a text field.

<div style="border: inset 2px #ccc;background:#fff;padding:2px;">
