So, I'm attempting to make my own website (Yeah, I finally sucked it up and started doing markup, sigh) - problem I'm having is I'm trying to center a button, and it's offset a little. Without the `<center>` it's all the way to the left. 

Also tried : 

```
style="align-items:center"

```

```
<div id="form-container" style="align-items:center;">
    <div>
        <fieldset>
        <center><a href="/ReduxLauncher.zip"><input class="button0" value="Install Redux" type="button" /></a></center>
        </fieldset>
    </div>
</div>

```
