I am a small button and... I am not!

<a class="win98btn" href="#">I am a small button</a>

And:

<a class="win98btn large" href="#">I am not!</a>

Make sure you have this in your <head> tag:

<link rel="stylesheet" type="text/css" href="http://res.cloudinary.com/cjprogstuff/raw/upload/CSS/Win98btns/win98btns.min.css" />

Unless, of course, you Download the source and minified bundle. In this case, use this:

<link rel="stylesheet" type="text/css" href="win98btns.css" />

Or:

<link rel="stylesheet" type="text/css" href="win98btns.min.css" />

Normalize.css is also recommended to ensure buttons look *exactly* the same across devices. This page uses it.
