Button with graphical icon on left:

Buttons with graphical icons on right (1st attempt)
These are all CSS except for the graphics on the right-hand side of each. It may not be possible to reliably match the left text portion with the right graphical portion. Impelementing hover states would require two images per button. These examples work OK in Mac Safari and Mac Chrome, but not Mac Firefox. Untested on Windows browsers yet.

Buttons with graphical icons on right (2nd attempt)
Revised versions of the above. Avoids the problems iintroduced by the irregular shape of the above designs. These examples should be fine in all relatively current browsers.

How they Work

The basic HTML looks like this:

<a href="#">make new list</a>

The CSS button styles in this example page are organized such that you can style a link as a button, choose the color & size, like this:

<a href="#" class="button buttonM FDpurple">make new list</a>
