Different CSS Styles for 10 List <li> items

Question

What i have here is this:

<ul class="bwp-rc-ulist">

<li class="recent-comment">Item 1</li>
<li class="recent-comment">Item 2</li>
<li class="recent-comment">Item 3</li>
<li class="recent-comment">Item 4</li>
<li class="recent-comment">Item 5</li>
<li class="recent-comment">Item 6</li>
<li class="recent-comment">Item 7</li>
<li class="recent-comment">Item 8</li>
<li class="recent-comment">Item 9</li>
<li class="recent-comment">Item 10</li>

</ul>

I want to add the following CSS styles:

li.list1, li.list6 { background-color: red; }
li.list2, li.list7 { background-color: blue; }
li.list3, li.list8 { background-color: black; }
li.list4, li.list9 { background-color: yellow; }
li.list5, li.list10 { background-color: gray; }

unfortunately, i cannot do that because the UL & LI is dynamically created by a wordpress plugin (Better Wordpress Comment & Except Plugin).

I've already read some nth-child thingy but it doesn't solve my case. maybe if someone can show me what the correct scripts?

I'm also looking for a script that works in IE7-9, chrome and ff.

Thank you very much.

CSS solution

ul.bwp-rc-ulist li:nth-child(1),
ul.bwp-rc-ulist li:nth-child(6) {
    background-color: red;
}

ul.bwp-rc-ulist li:nth-child(2),
ul.bwp-rc-ulist li:nth-child(7) {
    background-color: blue;
}

ul.bwp-rc-ulist li:nth-child(3),
ul.bwp-rc-ulist li:nth-child(8) {
    background-color: black;
}

ul.bwp-rc-ulist li:nth-child(4),
ul.bwp-rc-ulist li:nth-child(9) {
    background-color: yellow;
}

ul.bwp-rc-ulist li:nth-child(5),
ul.bwp-rc-ulist li:nth-child(10) {
    background-color: gray;
}

​ or if you prefer it a bit more compact:

ul.bwp-rc-ulist li:nth-child(5n+1) {
    background-color: red;
}

ul.bwp-rc-ulist li:nth-child(5n+2) {
    background-color: blue;
}

ul.bwp-rc-ulist li:nth-child(5n+3) {
    background-color: black;
}

ul.bwp-rc-ulist li:nth-child(5n+4) {
    background-color: yellow;
}

ul.bwp-rc-ulist li:nth-child(5n+5) {
    background-color: gray;
}

jQuery solution (with your CSS)

$('ul.bwp-rc-ulist li.recent-comment').each(function(index) {
    $(this).addClass("list" + (index + 1));
});​

HTML:

<ul id="ulEle"  class="bwp-rc-ulist">
    <li class="recent-comment">Item 1</li>
    <li class="recent-comment">Item 2</li>
    ...
</ul>

OR:

<div  id="ulEle">
    <ul  class="bwp-rc-ulist">
        <li class="recent-comment">Item 1</li>
        <li class="recent-comment">Item 2</li>
        ...
    </ul>
</div>

JS:

<script type="text/javascript">
  var ulGet=document.getElementById("ulEle");
  var liList=ulGet.getElementsByTagName("li");
  for(var i=0;i<liList.length;i++)
  {
      liList[i].style.className="list"+(parseInt(i)+1);
  }
</script>
