IE 和移动 Safari 截断文本..可能是行高问题？

Question

我的页面可以在 Chrome、Safari、Firefox 和 Opera 中正确（且美观）显示，但在 Internet Explorer 和 iPhone 的 Safari 移动版本中稍微重新格式化。具体来说，它的格式仅比可见区域大一点，从而导致文本被截断。可能是行高问题。有什么解决办法吗？当我们这样做时......IE 的文本看起来如此尴尬是怎么回事？我是新手..他们不支持Helvetica？？

非常感谢所有建议。

    <div id="bio_left">
     <p class="justify">People often say it's hard to describe the sound of his records and categorizing him often presents an even bigger challenge, but what is truly undeniable and inarguable is that Fernando Garibay is a hit-making producer, DJ and artist. As multi-instrumentalist who plays guitar, keyboards, drums, bass, a formally trained arranger for string and brass sections and a programmer, with a proficiency that rivals top session players but with a uniqueness that only a seasoned "artist" producer yields, he is able to communicate through music unlike anyone else.</p>
