#DivShow li{float:left;position:relative; cursor:pointer;}
#DivRight ul
{
height: 100%;
text-align:center;
color: #1570a6;
list-style:none;
text-decoration:none;
table-layout:fixed;
display:table;
}
#DivRight li{cursor:pointer; display:table-cell;
margin-top:40px; height:20px; float:left;}
#UlIcon
{
height: 100%;
list-style:none;
text-align:center;
padding-left: 5px;
text-decoration:none;
}
#UlIcon li {float:right; margin-left:25px; width : 40px; height:100%;}
img {
display:inline-block;
width:40px;
height:100%;
cursor:pointer;
}
ASP.NET
<div id="DivHeader">
<div id="DivShow">
<ul> <li> Show All </li></ul>
</div>
<div id="DivRight">
<ul> <li > Admin </li></ul>
</div>
<div id="DivMenuRight">
<ul id="UlIcon">
<li id="LiLog"> <img src="IMG/New.png" alt="" /></li>
<li id="LiDelete"> <img src="IMG/Delete.png" /></li>
<li id="LiSave"> <img src="IMG/Save.png" /></li>
<li id="LiNew"> <img src="IMG/New.png" /> </li>
</ul>
</div>
</div>
But bottom border line overlap with images only so how can i get the solution?
