Here is my CSS

   button {
    border: 0 none;
    cursor: pointer;
    padding: 0 15px 0 0;
    text-align: center;
    height: 30px;
    line-height: 30px;
    width: auto;
}
button a {
    color:white;
    text-decoration:none;
}

button.rounded {
    background: transparent url(/images/button/btn_right.png) no-repeat scroll right top;
    clear: left;
    font-size: 0.8em;
}

button span {
    display: block;
    padding: 0 0 0 15px;
    position: relative;
    white-space: nowrap;
    height: 30px;
    line-height: 30px;
}

button.rounded span {
    background: transparent url(/images/button/btn_left.png) no-repeat scroll left top;
    color: #FFFFFF;
}

button.rounded:hover {
    background-position: 100% -30px;
}

button.rounded:hover span {
    background-position: 0% -30px;
}

button::-moz-focus-inner {
border: none;
}

Here is the code for my "button" with a link in it.

<button class="rounded"><span><a href="profile.php">Profile</a></span></button>

The issue is it does not link to the href when i click on it. Anyone know why?
