css - forcing width of menu items to take up 100%

i have this site:

www.yoursdproperty.com

i need the top menu items HOME, BUYING PROPERTY, SELLING PROPERTY ETC...

to take up 100% of the width of the top bar. if i add more items, i went them to size accordingly.

here is the CSS associated with this menu bar. is there something i can change here to do that?

You might try using display: table-cell instead of list-style: none on the top level lis, and then set display: table; width: 100% on the top level ul. This forces the the lis to be displayed using the table layout algorithm, which allows you to define how much space you want the whole thing to take up (in this case 100%).

I would use a table for that. It's one of the situations that I find a table is most appropriate also means that you don't have to worry about it later should your require adding more links in the future.

I'm not sure that's possible. I think you will need to set the width of each menu element specifically to ensure it spans the full width of its container, and make the appropriate adjustments to your CSS file once you add new elements.

Danny answer work well here are the main element:

 #menu_conteneur ul{
    display:table;
    width: 100%;    
 }

 #menu li{
    display: table-cell; 
 }

 #menu li a{
    display: block;
 }
