jquery - Making radio buttons look like buttons instead

Question

I would like to have a set of radio buttons for a donation form, however I want them to look like buttons instead of the circle dials.

What is the best approach to making something like that? Also, keep in mind, it has to work with IE8.

Here's what I have so far, http://jsfiddle.net/YB8UW/

.donate-now {
     list-style-type:none;
     margin:25px 0 0 0;
     padding:0;
}

.donate-now li {
     float:left;
     margin:0 5px 0 0;
}

.donate-now label {
     padding:5px;
     border:1px solid #CCC; 
     cursor:pointer;
}

.donate-now label:hover {
     background:#DDD;
}

Thank you

It can be done with CSS and without the need of a large framework. I have done this with checkboxes and radio buttons.

This works without adding new HTML, or bringing in any JS libraries. => jsFiddle

THE NEW ORDER OF THE HTML

This is the ten minute hacky version, you can clean it up even further, but it shows a good example of how simple it is.

.donate-now {
  list-style-type: none;
  margin: 25px 0 0 0;
  padding: 0;
}

.donate-now li {
  float: left;
  margin: 0 5px 0 0;
  width: 100px;
  height: 40px;
  position: relative;
}

.donate-now label,
.donate-now input {
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
}

.donate-now input[type="radio"] {
  opacity: 0.01;
  z-index: 100;
}

.donate-now input[type="radio"]:checked+label,
.Checked+label {
  background: yellow;
}

.donate-now label {
  padding: 5px;
  border: 1px solid #CCC;
  cursor: pointer;
  z-index: 90;
}

.donate-now label:hover {
  background: #DDD;
}

<ul class="donate-now">
  <li>
    <input type="radio" id="a25" name="amount" />
    <label for="a25">$25</label>
  </li>
  <li>
    <input type="radio" id="a50" name="amount" />
    <label for="a50">$50</label>
  </li>
  <li>
    <input type="radio" id="a75" name="amount" checked="checked" />
    <label for="a75">$75</label>
  </li>
  <li>
    <input type="radio" id="a100" name="amount" />
    <label for="a100">$100</label>
  </li>
  <li>
    <input type="radio" id="other" name="amount" />
    <label for="other">other:</label>
  </li>
  <li>
    <input type="text" id="otherAmount" name="numAmount" />
  </li>
</ul>
