html: Centering issue with HTML & CSS

jeudi 7 juillet 2016

currently my issue is this: http://prntscr.com/bhafke Browser: Chrome

For some reason, it's not centering properly. Below you'll find my code:

HTML:

<body>
    <div id="wrapper">
        <h1>Test Text</h1>
    </div> <!-- wrapper div end -->
</body>

CSS:

#wrapper {
    width: 100%;
    max-width: 960px;
    margin: 0 auto;
}
