Answer 1

Delete the display: inline-block; from de #info_new_ul li
and use a float:left for the <li>.
#info_new_ul li {
....
float:left;
}
Your JsFiddle but updated with the new code

Answer 2

You should use float:left for li tags.
#info_new_ul li {
float:left;
margin-left: 2px;
padding: 5px;
color: #fff;
font-family: trebuchet ms;
font-size: 19px;
font-weight: lighter;
text-align: justify;
word-wrap:break-word;
}
