Align two inline-blocks left and right on same line

Question

How can I align two inline-blocks so that one is left and the other is right on the same line? Why is this so hard? Is there something like LaTeX\'s \\hfill that can consume

Answer 1

If you don't want to use floats, you're going to have to wrap your nav:

<header>
<h1>Title</h1>
<div id="navWrap">
<nav>
    <a>A Link</a>
    <a>Another Link</a>
    <a>A Third Link</a>
</nav>
</div>
</header>

...and add some more specific css:

header {
//text-align: center; // will set in js when the nav overflows (i think)
width:960px;/*Change as needed*/
height:75px;/*Change as needed*/
}

h1 {
display: inline-block;
margin-top: 0.321em;
}

#navWrap{
position:absolute;
top:50px; /*Change as needed*/
right:0;
}

nav {
display: inline-block;
vertical-align: baseline;
}

You may need to do a little more, but that's a start.

I think one possible solution to this is to use display: table:

.header {
  display: table;
  width: 100%;
  box-sizing: border-box;
}

.header > * {
  display: table-cell;
}

.header > *:last-child {
  text-align: right;  
}

h1 {
  font-size: 32px;
}

nav {
  vertical-align: baseline;
}

Answer 3

give it float: right and the h1 float:left and put an element with clear:both after them.

Answer 4

For both elements use

display: inline-block;

the for the 'nav' element use

float: right;

Answer 5

Taking advantage of @skip405's answer, I've made a Sass mixin for it:

@mixin inline-block-lr($container,$left,$right){
    #{$container}{        
        text-align: justify; 

        &:after{
            content: '';
            display: inline-block;
            width: 100%;
            height: 0;
            font-size:0;
            line-height:0;
        }
    }

    #{$left} {
        display: inline-block;
        vertical-align: middle; 
    }

    #{$right} {
        display: inline-block;
        vertical-align: middle; 
    }
}

It accepts 3 parameters. The container, the left and the right element. For example, to fit the question, you could use it like this:

@include inline-block-lr('header', 'h1', 'nav');

Answer 6

New ways to align items right:

Grid:

.header {
        display:grid;
        grid-template-columns: 1fr auto;
    }

Demo

Bootstrap 4. Align right:

<div class="row">
      <div class="col">left</div>
      <div class="col">
          <div class="float-right">element needs to be right aligned</div>
      </div>
</div>
