The above bottom footer blocking a bug

When setting the style for the footer at the bottom:

.footer{

　　position: fixed;

　　height: 49px;

　　bottom: 0;

　　background: #fff;

}

This will block the contents of the above, modified as follows:

Add to the body style:

body{

　　padding-bottom: 49px; height // like and consistent set of fixed

}
