I am able to center my elements horizontally, but not vertically. I found couple of questions on stackoverflow regarding the same issue but the suggestions in those didn't work for some reason. Any suggestions? This is what I am going for: http://i62.tinypic.com/n4gzcw.png
Here is what I have so far:
    <style>
.container {
    width: 100%;
    height: 100%;
    background-color: red;
    position: absolute;
    top:0;
    bottom: 0;
    left: 0;
    right: 0;
    margin: auto;
}
.datetime {
    width: 50%;
    margin-left: auto; 
    margin-right: auto;
    margin-top: 15%;
    background-color: white;
    text-align: center;
}
.main {
    width: 100%;
    margin-left: auto; 
    margin-right: auto;
    margin-top: 3%;
    background-color: yellow;
    text-align: center;
}
.left {
    width: 25%;
    float: left;
}
.left img {
    width: 50%;
    height: 50%;
    max-width: 80px;
    max-height: 80px;
}
.mid {
    width: 50%;
    text-align: center;
    float: left;
    padding-top: 5%;
    font-size: 1em;
}
.right {
    width: 25%;
    float: left;
}
.right img {
    width: 50%;
    height: 50%;
    max-width: 80px;
    max-height: 80px;
}
.stadium {
    width: 50%;
    margin-left: auto; 
    margin-right: auto;
    background-color: white;
    text-align: center;    
}
</style>
