How to Right-align flex item?

Question

Is there a more flexbox-ish way to right-align "Contact" than to use position: absolute?

.main {
  display: flex;
}

.a,
.b,
.c {
  background: #efefef;
  border: 1px solid #999;
}

.b {
  flex: 1;
  text-align: center;
}

.c {
  position: absolute;
  right: 0;
}

<h2>With title</h2>
<div class="main">
  <div class="a"><a href="#">Home</a></div>
  <div class="b"><a href="#">Some title centered</a></div>
  <div class="c"><a href="#">Contact</a></div>
</div>

<h2>Without title</h2>
<div class="main">
  <div class="a"><a href="#">Home</a></div>
  <!--<div class="b"><a href="#">Some title centered</a></div>-->
  <div class="c"><a href="#">Contact</a></div>
</div>

Answer 1

A more flex approach would be to use an auto left margin (flex items treat auto margins a bit differently than when used in a block formatting context).

.c {
    margin-left: auto;
}

Updated fiddle:

.main { display: flex; }
.a, .b, .c { background: #efefef; border: 1px solid #999; }
.b { flex: 1; text-align: center; }
.c {margin-left: auto;}

<h2>With title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <div class="b"><a href="#">Some title centered</a></div>
    <div class="c"><a href="#">Contact</a></div>
</div>
<h2>Without title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <!--<div class="b"><a href="#">Some title centered</a></div>-->
    <div class="c"><a href="#">Contact</a></div>
</div>

Answer 2

Here you go. Set justify-content: space-between on the flex container.

.main { 
    display: flex; 
    justify-content: space-between;
  }
.a, .b, .c { background: #efefef; border: 1px solid #999; }
.b { text-align: center; }

<h2>With title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
    <div class="b"><a href="#">Some title centered</a></div>
    <div class="c"><a href="#">Contact</a></div>
</div>
<h2>Without title</h2>
<div class="main">
    <div class="a"><a href="#">Home</a></div>
<!--     <div class="b"><a href="#">Some title centered</a></div> -->
    <div class="c"><a href="#">Contact</a></div>
</div>
