Trying to align my icon font element at center is not working

I´m trying to do an effect when I hover over an image, I want to show a dark box closing and when the box is closed, I Want to show an icon font on the center of my image.

The effect already is working but my icon font is not staying centered.

I already tried margin:0 auto, text-align:center, but nothing is working.

I format my icon font here:

#info>i 
    {
        font-size:1.7em;
        color:#ccc;
        margin:0 auto;
    } 

But only the color and font-size are working, the margin, text-align etc. don't work. Does anybody understand what can be happening here?

My jsfiddle showing the problem:

My Html:

<div class="view second-effect">

      <div class="mask">

</div>

My CSS:
