Question

I am developing a site and want to centralize this site in the center of the screen (horizontally and vertically) but can not.
I could only centers it horizontally.

Since I’ve been searching and the solutions I found when I try to apply them to my site, it all mangled.

This is the website http://amsdarquitetura.com.br/

This is what you need:

<style type="text/css">

#global {
    position:absolute;
    width: 700px;
    height: 400px;
    margin-top: -200px; /* half of the height */
    margin-left: -350px; /* half of the width */
    left: 50%;
    top: 50%;

    border: 1px solid #333;
    background-color: pink;
}

</style>

Put this on your parent div.
