すべてのブラウザで斜めの線で左揃えのテキストを実現するにはどうすればよいですか?

<code class="less">.loop(@i) when (@i > 0){
  .loop((@i - 1));
  .space@{i}{
    width: floor(@i*@hSize/(1/tan(5deg)));
  }
}
@hSize: 15px;
.space {
  float: left;
  clear: left;
  width: @hSize;
  height: @hSize;
}</code>

<code class="html"><p>
  <span class="space space1"></span>
  <span class="space space2"></span>
  <!-- (...) -->
  <span class="space space11"></span>
