Move li to the right in menu

Question

I have a menu, and I would like to have the last 3 options (some images for Facebook/Twiter/Gmail) to be aligned to the right. So far I tried: li:last-child { float:right;}- combine the 3 images in one to have the last option to the right, but not even so works float: right; - the same result as above text-align: right; - no change

#nav { 
    background-color: #e26a63;
    padding: 0;
    margin: 0;
    font-family: FONT;
    font-size: 20px;
}
   
#wrap {
    padding-left: 60px;
    height: 100px;
    width: 100%;
    margin: 0 auto;
    display: table-cell; 
    vertical-align: bottom;

}
#nav ul {
    list-style-type: none;
    padding: 0;
    margin: 0;
    position: relative;
    min-width: 225px; 
}
#nav ul li {
    display: inline-block;
}
#nav ul li:hover {
    background-color: #cb5f59;
}

#nav ul li:after {
  content: "";
  font-size: 0;
  display: block;
  height: 5px;

}
#nav ul li:hover:after {
  background: #9e4a45;
}
#nav ul ul li:hover:after {
  background: transparent;
}
#nav ul li a, visited {
    color: white;
    display: block;
    padding: 15px;
    text-decoration: none;
}
#nav ul li:hover ul {
    display: block;
}
#nav ul ul {
    display: none;
    position: absolute;
    background-color: #e26a63;
    border-top: 0;
    margin-top: 5px;
        z-index: 10;
}
#nav ul ul li {
    display: block;
}
#nav ul ul li a:hover {
    color: white;
}

Flexbox can do that:

  padding: 0;
  margin: 0;
  font-family: FONT;
  font-size: 20px;

#wrap {
  height: 100px;
}
#nav ul {
  list-style-type: none;
  padding: 0;
  margin: 0;
  position: relative;
  display: flex;
  align-items: center;
}
#nav ul li {} #nav ul li:hover {

Answer 2

First of all:

#nav {
    display: table;
    width: 100%;
}

.alignright { float: right; }
