如何在網頁中將整段文字左右對齊

1中文對齊:<br>
<div style="font-size:12px;width:300;text-align:justify; text-justify:inter-ideograph">
只有付出的愛是痛苦的，但比這更痛苦是愛一個人卻沒有勇氣讓那人知道你的感情。</div>

1英文對齊:<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>
