I have a vertical menu having an item “Click here to get the scientific name”.

on hover it is showing like

I need to get the overflow part after the black background image to be in the next line(i cannot increase the image width at all.). How can I write the style for that.
css:
on hover
{
display: block;
background: url('/../.png') no-repeat 0px 2px #2F2F31;
text-decoration: none;
color:..;
}
This is coming under
<td>
<div id="first">
<ul id="second">
<li><a href="">Click here to get the scientific name</a>
And css:
#first {
display: block;
width: 180px;
min-height: 50px;
float: left;
}
ul#second {
display: block;
clear: both;
margin: 50px 0px 12px 0px;
border-bottom: 1px solid
#C8C8C8;
}
ul#second li {
border-top: 1px solid
#C8C8C8;
padding: 0px;
display: block;
}
ul#second li a {
color:
#004C8E;
margin: 4px 0px 4px 0px;
padding: 4px 0px 4px 12px;
display: block;
text-decoration: none;
font-size: 12px;
background: url('/../.png') no-repeat 0px 2px;
}
td {
margin: 0;
padding: 0;
border: 0;
outline: 0;
font-size: 100%;
vertical-align: baseline;
background:
transparent;
}
On hover, you should explicitly set the
widthof the element to equal the width of the image.
