                <div class="pos-r">
  <label for="lol">
    My label
  <p id="desc" class="desc">
    instructions for this text field. <a href="#!">More instructions?</a>
  <input id="lol" aria-describedby="desc">


                .pos-r {
  position: relative;

/* use the label's pseudo element to create a hit area that spans the full height and with of the wrapping position relative div. */
.pos-r label:after {
  position: absolute;
  height: 100%;
  width: 100%;
  left: 0;
  top: 0;
  content: "";

/* set the input to be at a higher z-index than the pseudo element */
.pos-r input {
  position: relative;
  z-index: 2;

/* style your description how you want */
.pos-r .desc {
  font-size: .75em;
  display: block;
  margin: .5em 0;

/* if you're looking to provide a larger hit area for your label/form control, adding a link into the mix seems like an odd choice.  but as this is a thing that definitely happens, let's account for it. */
.pos-r .desc a {
  position: relative;
  z-index: 2;

  The following CSS is only for the demo styling. 
*:before {
  box-sizing: border-box;
body {
  padding: 3em;
  font-size: 1.2em;
  font-family: arial;

input {
  width: 100%;
  font-size: inherit;
  padding: .25em;
  border: 1px solid;

input:focus {
  border-color: blue;
  box-shadow: 0 0 0 2px blue;

.pos-r {
  margin: auto;
  max-width: 20em;


  This technique allows for 
  larger hit areas to activate 
  a form control, without having 
  to muddy up a form control's 
  accessible name with
