Finally, I find-out some CSS style which help me to overcome my problem:
CSS:
width : 440px;
white-space: pre; /* CSS 2.0 */
white-space: pre-wrap; /* CSS 2.1 */
white-space: pre-line; /* CSS 3.0 */
white-space: -pre-wrap; /* Opera 4-6 */
white-space: -o-pre-wrap; /* Opera 7 */
white-space: -moz-pre-wrap; /* Mozilla */
white-space: -hp-pre-wrap; /* HP Printers */
word-wrap: break-word;
-moz-hyphens:auto;
-webkit-hyphens:auto;
-o-hyphens:auto;
hyphens:auto;
text-align: justify;
