CSS3 Flex: Pull child to the right - html

Question

here's what I have Fiddle
ul {
display: flex;
justify-content: flex-start;
flex-direction: row;
align-items: center;
width: 100%;
height: 100px;
background: #333;
padding: 15px;
}
ul li {
padding: 15px;
margin: 5px;
background: #efefef;
border: 1px solid #ccc;
display: inline-block;
list-style: none;
}
#item-1 {
height: 50px;
}
#item-2 {
height: 70px;
}
<ul>
<li id="item-1">Home</li>
<li id="item-2">Menu</li>
<li>More</li>
<li>Stuff</li>
<li>Settings</li>
</ul>
I want the last item inside the flex-box to be pulled to the right ("Settings" in my fiddle) while keeping all other items the way they are. The "Settings"-item should also be centered vertically and everything.
align-self: flex-end pushes the item to the bottom (I want it on the right).
I would very much prefer a solution using flex-box because my items have variable heights and should always be centered vertically.
What is the cleanest way to achieve this?
Thanks for your help!

Simple fix, use an auto-adjusting margin:
ul li:last-child {
margin-left: auto;
}
You may also want to not use width: 100% so that the element stays inside the visible area:
ul {
display: flex;
justify-content: flex-start;
flex-direction: row;
align-items: center;
/* width: 100%; */
height: 100px;
background: #333;
padding: 15px;
}
