How can I add hover effect to dropdown menu

How can I add hover effect to dropdown menu item background with css?

I want background color change when I hover over it, from green to red for instance, how css code should look?

Following css rule is only static

/* child item container */
div#<?php echo $id; ?> ul.maximenuck li div.floatck {
background : green;
border : 1px solid #707070;

Thanks in advance.

Hi
In css you can use the :hover pseudo class

PS : "hello" or "hi" would be a good starting point

Hi,

to everyone, especially to you ced1870

I am sorry I forgotten to sa hello. My head was full of css code and burning.

ced1870 thank you for taking your time and effort to answer to my question.

I didn't quite understood how can add pseudo class

I did my best is it like this?

div#<?php echo $id; ?> ul.maximenuck li div.floatck a:hover {
background-color: 9e005d;
}

I did it just that, but nothing happens.

I have run out of css ideas, sorry.

Thanks in advance
