This is my solution. Just add this class to your CSS content.

.align-middle {
  display: flex;
  justify-content: center;
  align-items: center;
}

Then your HTML would look like this:

<div class="col-xs-12 align-middle">
  <div class="col-xs-6" style="background-color:blue;">
    <h3>Item</h3>
    <h3>Item</h3>
  </div>
  <div class="col-xs-6" style="background-color:red;">
    <h3>Item</h3>
  </div>
</div>

.align-middle {
  display: flex;
  justify-content: center;
  align-items: center;
}

<html>
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">

<!DOCTYPE html>
    <title>Title</title>
  </head>
  <body>
    <div class="container">
      <div class="row">
        <div class="col-xs-12 align-middle">
          <div class="col-xs-6" style="background-color:blue;">
            <h3>Item</h3>
            <h3>Item</h3>
          </div>
          <div class="col-xs-6" style="background-color:red;">
            <h3>Item</h3>
          </div>
        </div>
      </div>
    </div>

I genuinely find the following code works using Chrome and not other browsers than the currently selected answer:
```
.v-center {
    display:table!important; height:125px;
}

.v-center div[class*='col-'] {
   display: table-cell!important;
   vertical-align:middle;
   float:none;
}
.v-center img {
   max-height:125px;
}
```

You may need to amend the heights (specifically on .v-center) and remove/change div on div[class*='col-'] for your needs.

This answer presents a hack, but I would highly recommend you to use flexbox (as stated in @Haschem answer), since it's now supported everywhere.

Demos link:
- Bootstrap 3
- Bootstrap 4 alpha 6

You still can use a custom class when you need it:

.vcenter {
    display: inline-block;
    vertical-align: middle;
    float: none;
}

<div class="row">
    <div class="col-xs-5 col-md-3 col-lg-1 vcenter">
        <div style="height:10em;border:1px solid #000">Big</div>
    </div><!--
    --><div class="col-xs-5 col-md-7 col-lg-9 vcenter">
        <div style="height:3em;border:1px solid #F00">Small</div>
    </div>
</div>

Bootply

Using inline-block adds extra space between blocks if you let a real space in your code (like ...</div> </div>...). This extra space breaks our grid if column sizes add up to 12:

<div class="row">
    <div class="col-xs-6 col-md-4 col-lg-2 vcenter">
        <div style="height:10em;border:1px solid #000">Big</div>
    </div>
    <div class="col-xs-6 col-md-8 col-lg-10 vcenter">
        <div style="height:3em;border:1px solid #F00">Small</div>
    </div>
</div>

Here, we've got extra spaces between <div class="[...] col-lg-2"> and <div class="[...] col-lg-10"> (a carriage return and 2 tabs/8 spaces). And so...

Enter image description here

Let's kick this extra space!!

<div class="row">
    <div class="col-xs-6 col-md-4 col-lg-2 vcenter">
        <div style="height:10em;border:1px solid #000">Big</div>
    </div><!--
    --><div class="col-xs-6 col-md-8 col-lg-10 vcenter">
        <div style="height:3em;border:1px solid #F00">Small</div>
    </div>
</div>

Enter image description here

Notice the seemingly useless comments ? They are important -- without them, the whitespace between the <div> elements will take up space in the layout, breaking the grid system.

There isn't any need for table and table-cells. It can be achieved easily using transform.

Example: http://codepen.io/arvind/pen/QNbwyM

Code:

.child {
  height: 10em;
  border: 1px solid green;
  position: relative;
}
.child-content {
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet" />
<div class="row parent">
  <div class="col-xs-6 col-lg-6 child">
    <div class="child-content">
      <div style="height:4em;border:1px solid #000">Big</div>
    </div>
  </div>
  <div class="col-xs-6 col-lg-6 child">
    <div class="child-content">
      <div style="height:3em;border:1px solid #F00">Small</div>
    </div>
  </div>
</div>

执念已碎

There are several ways you can do it:
1. Use
```
display: table-cell;
vertical-align: middle;
```
  and the CSS of the container to
```
display: table;
```
2. Use padding along with media-screen for changing the padding relative to the screen size. Google @media screen to know more.
3. Use relative padding
  
  I.e., specify padding in terms of %
