Label tags will ensure that screen readers match the right label to the right input box in all your forms.
Here's the bare-bones HTML for the form segment above. It looks OK, but is susceptible to misinterpretation by screen reader/=.
<input type="text" name="hometown"> </form>
Here's the same code with the label tag info added in.
<label for ="town">Your hometown</label>
<input type="text" name="hometown" id="town">
Because the "label for" (town) matches the input "id" (town), the screen reader gets it right, announcing "Your hometown" when the user clicks on the blank.
