Answer 1

if you don't set a width for btn:

1. parent - text-align: center
2. button child - use display:inline-block instead of display: block

.wrap {
    text-align: center;
}
.center-block {
    display: inline-block;
}

<div class="wrap">
    <input value="Button" class="center-block" type="submit" />
</div>
