How to vertical align this div

This i开发者_如何学Pythons my actual code :

<div class="main_right_content">
    <div class="main_right_content_text">
        my text is here and could be as long as possible. for example I write this code some times : my text is here and could be as long as possible. for example I write this code some times : my text is here and could be as long as possible. for example I write this code some times
    </div>

    <a class="main_right_content_link" href="#">Go</a>
</div>

And I'd like, when I minimize the window, put the link "go" in the middle about vertical align. In fact it stay always in top.

How can I do this with css(2)?

You can use position: relative on the container div combined with position: absolute; right: 0; top: 50%; margin-top: -<height/2>px on the link.

This Solution Matched me perfectly. Even if it is a link or just a text inside the div, this CSS Class could vertically align the content inside the DIV

 .verticalCenterDivText{
        height: 29px;
        line-height: 29px;
    }
