Trim text (with CSS?) in highscores template

Question

I'm building a highscores page template, And would like to trim the username (ideally with CSS) if the username and/or score is too long. See this picture :

I can use

white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
overflow-y:none;

To trim the username, but how can I trim it relatively to the score length ?

Have you got an idea of how doing this ? Here's a Codepen of my current code : http://codepen.io/anon/pen/yymZGM

Thanks

Answer 1

Just move the score span (which is floated right) before the name

#highscores {
  width: 400px;
  padding: 1em;
  background-color: yellow;
  margin: auto;
  font-size: 1.5em;
}
#highscores .round {
  font-size: 1.2em;
  line-height: 1.2em;
  height: 1.2em;
  position: relative;
  background-color: red;
  padding: 0.4em 0;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
  overflow-y: none;
}
#highscores .round .round-index {
  padding-right: 2%;
}
#highscores .round .round-author {
  font-weight: 700;
  width: 60%;
}
#highscores .round .round-score {
  width: 28%;
  float: right;
  text-align: right;
}

<div id="highscores" class="celio-black">
  <p id="round-4" class="round">
    <span class="round-score">75</span>
    <span class="round-index">01</span>
    <span class="round-author">grosbouff</span>

  </p>
  <p id="round-1" class="round">
    <span class="round-score">75486987</span>
    <span class="round-index">02</span>
    <span class="round-author">I have a super long name isn't it ?</span>

  </p>
</div>
