I have a repeatable wrapper element with children elements: content element, with left and right elements, all divs.
I want to add some text (ie, "Retired"), rotated by few degrees, like a watermark in the background of content. This can't be a background image, because this text shall be localized (and for maintenance purpose, easier to change a text instead of an image).
Next image shows a disposition of text "Retired" (without showing left and right elements):

Here's the basic HTML layout of this element, it might be useful:
<div class="wrapper">
  <div class="leftcolumn">Left column</div>
  <div class="content">
    <h1>Text Text Text Text Text Text</h1>
    <p>Text Text Text Text Text Text Text Text Text</p>
  </div>
  <div class="rightcolumn">Right column</div>
</div>
And CSS:
.wrapper {
    margin: 0 auto;
    width: 450px;
    display:block;
    background-color:#222222;
    border-radius: 5px;
}
.content {
    float: left;
    width: 318px;
    padding-left: 5px;
}
.leftcolumn {
    width: 50px;
    float: left;
}
.rightcolumn {
    width: 75px;
    float: left;
}
.leftcolumn {
    width: 50px;
    float: left;
}
.rightcolumn {
    width: 75px;
    float: left;
}
