ul.menu a:active { color: white; background-color: red; } 18.
Roll-over effects: Borders ul.menu a:link, ul.menu a:visited {
padding: 0.2em 0.4em; border-left: 0.4em solid #2b3d91; color:
#2b3d91; background: #f6f6ff; } ul.menu a:hover { border-left:
0.4em solid #aea; color: white; background: #369; } ul.menu
a:active { border-left: 0.4em solid red; } 19. Roll-over effects:

-999em; } ul.menu li:hover ul { left: auto; margin-left: 352px;

CSS
- Sample data: Home page This menu item has an ItemID of 1. There
can be only onecurrentmenu item so it has anidof current This menu
item is theparentof at least one sub-menu so it has a class of
parent. 21. Joomla menu CSS

- Sample data: What's New in 1.5? page There can be
manyactivemenu items so they have aclassof active 22. Joomla menu
item states ul.menu li#current a:link, ul.menu li#current
a:visited, ul.menu li.active a:link, ul.menu li.active a:visited {
color: #f0f0f0; background: #2b3d91; border-left: 0.4em solid #fe3;
} ul.menu li#current a:hover, ul.menu li.active a:hover {
border-left: 0.4em solid #aea; } Remember: there's only one current
item But there can be more than one active item Sometimes you may
need to change the hover colour for the current item 23. Joomla
menu CSS cascade /* Basic link styles - Joomla states */ ul.menu
li#current a:link, ul.menu li#current a:visited, ul.menu li.active
> a:link, ul.menu li.active > a:visited {} /* Basic menu
styles */ ul.menu {} /* Hover states */ ul.menu a:hover, ul.menu
li#current a:hover, ul.menu li.active a:hover {} /* Suckerfish -
Hide/show sub-menus */ ul.menu li ul { position: absolute; left:
-999em; } ul.menu li:hover ul { left: auto; margin-left: 342px;
margin-top: -44px; } /* Basic link styles */ ul.menu a:link,
ul.menu a:visited {} /* Styles for parent menus */ ul.menu
li.parent {} /* Active states */ ul.menu a:active, ul.menu
li#current a:active, ul.menu li.active a:active {} 24. Background
images ul.menu a:link, ul.menu a:visited { padding: 5px 5px 5px
25px; background: url(../images/arrow.png) no-repeat center left; }
The path to the image is relative to the CSS file, not the template
root Increase the left padding to allow room for the background
image Use center to centre the image vertically 25. Background
images ul.menu a:link, ul.menu a:visited { margin-top: 10px;
padding: 5px 5px 5px 25px; background: url(../images/button_0.png)
no-repeat center left; color: white; } ul.menu a:hover {
background: url(../images/button_1.png) no-repeat center left; }

27. Joomla Menu Tag ID Module Manager -> Module: [Edit]
- Enter an id here and it will be added to the UL here Instead of
ul.menu, use ul#main-menu 28. Joomla Menu Class Suffix
- Module Manager -> Module: [Edit] Enter a suffix here and it
will be added to the UL here 29. Joomla Menu Class Suffix Tip: If
you enter a Menu Class Suffix with a leading space, you will get
separate CSS classes in the UL. Tip: You can have as many classes
in the UL as you like.
