如何垂直对齐div？

Question

I have a section where I have floated content on the left and right. The left content is gonna be bigger that the right (on height) so I want the right content to be vertically centered/aligned to the left content. How can I make that ?

Example image:

The blue content is gonna be mostly h1 and p and the red one just one small image and 1-2 words below it.

Code:

 .inner { background: none repeat scroll 0 0 #FFFFFF; max-width: 576px; width: 100%; padding: 37px 34px 37px 34px; } .leftSide { width: 80%; float: left; border-right: 1px solid #f2f2f2; } .leftSide a h1 { font-size: 20px; color: #3c3c3c; text-transform: none; font-family: 'Open Sans light'; } .leftSide span p { font-size: 12px; padding-top: 2px; } .leftSide .description { font-size: 13px; padding: 15px 0 25px 0; color: #6a6868; line-height: 1.4; font-family: 'Open Sans'; } .leftSide .button { background-color: #8D1313; border-radius: 3px; color: #FFFFFF; font-family: 'Open Sans light'; font-size: 13px; margin-top: 20px; padding: 7px 10px; } .rightSide { float: right; width: 15%; height: 100%; text-align: center; } .rightSide p { text-align: center; color: #565656; font-size: 14px; font-family: 'Open Sans'; } 

 <div class="inner clearfix"> <div class="leftSide"> <a href="#"> <h1>Jsut a simple Headline</h1> </a> <span> <p> 15 April / 4 Comments / 434Views </p> </span> <p class="description">Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p> <a class="button" href="#">learn more...</a> </div> <div class="rightSide"> <img src="img/author.png" alt="author" /> <p>J.Smith</p> </div> </div>

I found a method that works. You will have to tweak it based on your code. JsFiddle here .

HTML:

<div id="myrow">
    <div id="content">Content<br/>alpha</div>
    <div id="rightside">Right Side</div>
</div>

CSS:

body {
    font-family: sans-serif;
    font-size: 20pt;
    box-sizing: border-box;
}
#myrow {
    vertical-align: middle;
    width: 100%;
    border: solid 1px black;
    position: relative;
}
#myrow:after {
    content: "";
    display: table;
    clear: both;
}
#content, #rightside {
    display: inline-block;
    float: left;
    margin: 0 auto;
    height: 3em;
    text-align: center;
    vertical-align: middle;
    color: white;
}
#content {
    width: 55%;
    background-color: #307FFF;
    line-height: 1.5em;
}
#rightside {
    width 45%;
    min-width: 45%;
    background-color: #F56362;
    line-height: 3em;
}

The line-height is what centers the text or image. You may need to adjust your line-heights to accommodate your content.
