将整段文字用代码左右对齐

如何在网页中将整段文字左右对齐

1中文对齐:<br>
<div style="font-size:12px;width:300;text-align:justify; text-justify:inter-ideograph">
只有付出的爱是痛苦的，但比这更痛苦是爱一个人却没有勇气让那人知道你的感情。</div>

1英文对齐:<br>
<div style="font-size:12px;width:300;text-align:justify;text-justify:inter-ideograph">It hurts to love someone and not be loved in return. But what is more painful is to love someone and never find the courage to let that person know how you feel.
</div>
