HTML span align center not working?

<span align="center" style="border:1px solid red;">
    This is some text in a div element!
</span> 

However, the align attribute is deprecated. You should use the CSS text-align property on the container.

<div style="text-align: center;">
    <span style="border:1px solid red;">
        This is some text in a div element!
    </span>
</div>
