My Blog will not "Center" Content

[BillSvoboda]

On my blog, I can't center any images (like a button or youtube video) although I have "centered" in the code and by selecting the "centered" option for alignment.  Is it a CSS issue with the style sheet?  Any suggestions?  Here is a post that I'm referring to... you can see the pink CTA button that will not center.

Any insight is appreciated, but I feel like it's an issue with the style sheet.  Thoughts?

i dont know what the problem is in the editor. 

But in the css i can se the problem.

OLD CODE

element.style {
    color: #ffffff;
    text-decoration: none;
    font-family: Helvetica, Arial, sans-serif;
    font-weight: bold;
    font-size: 16px;
    line-height: 20px;
    padding: 10px;
    display: inline-block;
    max-width: 300px;
    border-radius: 5px;
    text-shadow: rgba(0, 0, 0, 0.247059) 0px -1px 1px;
    box-shadow: rgba(255, 255, 255, 0.498039) 0px 1px 3px inset, rgba(0, 0, 0, 0.498039) 0px 1px 3px;
    background: #f491a3;
}

NEW CODE

element.style {
    color: #ffffff;
    text-decoration: none;
    font-family: Helvetica, Arial, sans-serif;
    font-weight: bold;
    font-size: 16px;
    line-height: 20px;
    padding: 10px;
    display: block;
    max-width: 300px;
    border-radius: 5px;
    text-shadow: rgba(0, 0, 0, 0.247059) 0px -1px 1px;
    box-shadow: rgba(255, 255, 255, 0.498039) 0px 1px 3px inset, rgba(0, 0, 0, 0.498039) 0px 1px 3px;
    background: #f491a3;
    margin: 0 auto;
    text-align: center;
}

As you can se i have added

margin: 0 auto;
text-align: center;

and change the display : inline-block;  to display: block;

Hoped it helped
