Is it possible to use label in h3?

Question

<h3><label for="fio">* Your name</label></h3>
<input required="required" id="fio" type="text" name="fio" maxlength="60" size="50">

Answer 1

Yes of course.
In this case, <label> increases the activation field <input>.
That is, there is no need to aim directly at <input>, you can click on "* Your name" and the input is activated.☺
