HTML and CSS Reference
• the background: the default state of the slider
buttons uses a plain white background.
You added background-color:#FFF to overwrite the
btn default background, but also added the property
background-position:-100px -100px; which isn't going to
show anything because the btn.png doesn't extend up
to a 100px width or height.
It's an intentional action to remove the image and
just leave only the background-color:#FFF; property.
The other properties in the above code (e.g. float and
margin ) are added to position the buttons.
Before including the arrows, position the p.navigation
selector with the help of position:absolute and some
right and top values (e.g. right:15px; and top:20px; ).
