IE和移动safari切断文本..可能是行高问题？

Question

我有一个在Chrome，Safari，Firefox和Opera中正确显示（并且精美）的页面，但在Internet Explorer和iPhone的移动版Safari中稍微重新格式化。具体来说，它的格式只比可见区域大一点，导致文本被截断。这可能是一个行高问题。它有什么解决方案吗？虽然我们正在努力... IE的文字看起来如此尴尬？我是新手..他们不支持Helvetica ??

非常感谢所有建议。

HTML：

    <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>
