I want the content to be centred in the page. However, it doesn't seem to work.

CSS:

        body {
         text-align: center;
        }
        .velkommen {
            text-align: center;
            font-family: Verdana;
            font-size: 28px;
            width: 400px;
            background-color: rgb(240, 255, 240);
            -webkit-box-shadow: black;
            border-radius: 50px
        }
        #links {
            font-family: Verdana;
            width: 300px;
            padding: 5px 20px 5px 20px;
        }

HTML:

<div class="velkommen">Velkommen til min hjemmeside</div>
<div id="links">Links:<br>Random Page!</div>

What is wrong?

Add this style to the div:

margin-left:auto;
margin-right:auto;
