Browser Compatibly

[BabbleOn]

I'm new to CSS and I've been previewing the following site in Safari (ver 3.1)
Lightstorm Photography
Can someone help me, I'm having the following problems with browser compatibility:
Why does the drop-down menu work on Firefox (mozilla 5.0) but NOT on IE (7.0) ?
Moana Robert Gallery - Adventure
Why doesn't ANY of the main content appear on Firefox like it does on IE?
These pages only work in Safari, what is causing the malfunction between IE and Firefox?
What do I need to change/add/delete within the CSS to look the same on Firefox, IE, AND Safari?
Thank you, in advance, for your help.

Hello,
Well first off, I would have to take a look at your HTML file as well as the CSS file to be able to see the lines of code inside these files to see if they are what is in fact causing the problem.

For the lightstorm photography:
There is a syntax error after you specify the mouseover event for the "home" button that may disrupt the other hover links on certain browsers that are not forgiving. there is an extra "/" just before the

 / </a>

<img id="Home" src="images/Home.gif" alt="" name="Home" width="27" height="26" border="0" /</a>

remove it.
In general though there differences in how different browsers render a certain page. Main differences are in javascript events and css attribute handling. Always check with all the browsers after major css or javascript additions to check for incompatibly. Thus you will be able to spot the innocent attribute/function easier.
