10.8 Line height calculations: the 'line-height' and 'vertical-align' properties

The baseline of an 'inline-block' is the baseline of its last line box in the normal flow, unless it has either no in-flow line boxes or if its 'overflow' property has a computed value other than 'visible', in which case the baseline is the bottom margin edge.

This is a common issue involving inline-block elements. In this case, the default value of the vertical-align property is baseline. If you change the value to top, it will behave as expected.

Updated Example

.position-data {
vertical-align: top;
}

You need to add vertical-align:top to those two elements:

.album-artwork, .track-info {
vertical-align:top;
}

jsFiddle example

The default vertical alignment is baseline, but you are looking for top instead.

Or you could set float:left; to 3 elements.

Make sure the line-height ratio on all the elements you're trying to align is the same also. If you're using a mix of DIV, P, H1-5, DT, DD, INPUT, BUTTON tags this will also cause irregularities in vertical alignment depending on what you've already defined elsewhere.

The elements inside .track-container are inline-level boxes in the same line box.

Therefore, their vertical alignment is specified by the vertical-align property:

This property affects the vertical positioning inside a line box of the boxes generated by an inline-level element.

By default, its value is baseline:

Align the baseline of the box with the baseline of the parent box. If the box does not have a baseline, align the bottom margin edge with the parent's baseline.

In this case, they all have baselines, which are calculated according to

The baseline of an 'inline-block' is the baseline of its last line box in the normal flow, unless it has either no in-flow line boxes or if its 'overflow' property has a computed value other than 'visible', in which case the baseline is the bottom margin edge.

The following image clarifies what's happening (the red line is the baseline):

Therefore, you can

Change the vertical alignment of the elements, e.g. to top, middle or bottom

.track-container > * {
vertical-align: middle;
}

.track-container {
padding: 0;
width: 600px;
height: 200px;
border: 1px solid black;
list-style-type: none;
margin-bottom: 10px;
}
.position-data {
overflow: none;
display: inline-block;
width: 12.5%;
height: 200px;
margin: 0;
padding: 0;
border: 1px solid black;
}
.current-position,
.position-movement {
height: 100px;
width: 100%;
margin: 0;
padding: 0;
border: 1px solid black;
}
.album-artwork {
display: inline-block;
height: 200px;
width: 20%;
border: 1px solid black;
}
.track-info {
display: inline-block;
padding-left: 10px;
height: 200px;
border: 1px solid black;
}
.track-container > * {
vertical-align: middle;
}

<div class="track-container">
<div class="position-data">
<div class="current-position">1</div>
<div class="position-movement">2</div>
</div>
<div class="album-artwork">fdasfdsa</div>
<div class="track-info">fdafdsa</div>
</div>

Set the overflow of the elements to something different than visible, e.g. hidden or auto, so that their baseline will be their bottom margin edge.

.track-container > * {
overflow: hidden;
}

.track-container {
padding: 0;
width: 600px;
height: 200px;
border: 1px solid black;
list-style-type: none;
margin-bottom: 10px;
}
.position-data {
overflow: none;
display: inline-block;
width: 12.5%;
height: 200px;
margin: 0;
padding: 0;
border: 1px solid black;
}
.current-position,
.position-movement {
height: 100px;
width: 100%;
margin: 0;
padding: 0;
border: 1px solid black;
}
.album-artwork {
display: inline-block;
height: 200px;
width: 20%;
border: 1px solid black;
}
.track-info {
display: inline-block;
padding-left: 10px;
height: 200px;
border: 1px solid black;
}
.track-container > * {
overflow: hidden;
}

<div class="track-container">
<div class="position-data">
<div class="current-position">1</div>
<div class="position-movement">2</div>
</div>
<div class="album-artwork">fdasfdsa</div>
<div class="track-info">fdafdsa</div>
</div>

Make sure the elements have no in-flow line box, so that their baseline will be their bottom margin edge. That is, the contents should be out of flow:

An element is called out of flow if it is floated, absolutely positioned, or is the root element. An element is called in-flow if it is not out-of-flow.

So for example, you can place the contents of the elements in a wrapper, and style it with float: left:

.track-container > * > .wrapper {
float: left;
}

.track-container {
padding: 0;
width: 600px;
height: 200px;
border: 1px solid black;
list-style-type: none;
margin-bottom: 10px;
}
.position-data {
overflow: none;
display: inline-block;
width: 12.5%;
height: 200px;
margin: 0;
padding: 0;
border: 1px solid black;
}
.current-position,
.position-movement {
height: 100px;
width: 100%;
margin: 0;
padding: 0;
border: 1px solid black;
}
.album-artwork {
display: inline-block;
height: 200px;
width: 20%;
border: 1px solid black;
}
.track-info {
display: inline-block;
padding-left: 10px;
height: 200px;
border: 1px solid black;
}
.track-container > * > .wrapper {
float: left;
}

<div class="track-container">
<div class="position-data">
<div class="current-position wrapper">1</div>
<div class="position-movement wrapper">2</div>
</div>
<div class="album-artwork">
<span class="wrapper">fdasfdsa</span>
</div>
<div class="track-info">
<span class="wrapper">fdafdsa</span>
</div>
</div>
