CMPS HTML Page Formatting issue

[ibaker]

I have a CMPS HTML Code Page and I seem to be getting many issues.

1. I am putting a background image on the page with:

<div style="background-image: url('styles/advertise_bg.jpg');background-position:center center; background-repeat:no-repeat;">

but the image only appears in IE and not Firefox...if I change the image to a .gif, it works in both IE and Firefox

I have a list on the page that is using a vb misc image:

<ul style="list-style-image: url('../images/misc/tick.png');">

The ticks show up in the editor but when the page is viewed it still shows the standard bullet point...I have tried div restore etc but nothing works

Any ideas?
