Question: What is the best method (cross browser) to utilize an input type button, as a browser back button?

Answer: 
Are you looking to do something like this?

```
<input type="button" onclick="history.back();" value="Back">

```

You could also use

```
<input type="button" onclick="history.go(-1);" value="Back">

```
```
<input type="button" onclick="history.back();" value="Back">

```

The reason I'd suggest this approach is that it's expandable. If you decide to do something more with your back buttons, or if browsers change (which happens all the time) it's simple to change the functionality in exactly one location, rather than having to hunt down every instance of `onclick="history.back()"`.
