Fill table cell with horizontal css menu - html

Question

I have a css menu (the source for which I downloaded because I don't know squat about css) contained in a div
<div id='cssmenu' style='float:right;'>
<ul>
<li id='index'><a href='index.php'><span>Home</span></a></li>
<li id='aboutus'><a href='aboutus.php'><span>About Us</span></a></li>
<li id='gallery'><a href='gallery.php'><span>Galley</span></a></li>
<li id='videos'><a href='videos.php'><span>Videos</span></a></li>
<li id='links'><a href='links.php'><span>Links</span></a></li>
<li id='contact'><a href='contact.php'><span>Contact</span></a></li>
</ul>
</div>
I have this inside of a <td> with a fixed width (let's say 500px for simplicity). I adjusted the padding in the css to get the width to fit nicely... at least in Firefox. When I look at it in Chrome, the last menu item overflows the width of the table cell and ends up below the rest of the menu.
My question is, how do I make the menu items equally spaced across the width of the table? setting padding to 0px makes everything look tiny and squished, and I still want the vertical padding.
here is my css (sorry, I know it's long)
#cssmenu,
#cssmenu ul,
#cssmenu ul li,
#cssmenu ul li a {
margin: 0;
padding: 0;
border: 0;
list-style: none;
line-height: 1;
display: block;
position: relative;

-moz-box-sizing: border-box;
box-sizing: border-box;
}
#cssmenu {

padding:0px;
display:table;
}
#cssmenu.align-right ul li {

border-right: 0;
border-left: 1px solid rgba(0, 0, 0, 0.22);
}
#cssmenu.align-right ul li a {
border-right: 0;

}

Answer 1

It would be easy if you are using table, but here you have ul so i suggest you to use calc() function if you can comfort with it. or wait for some another solution. I have tested it with your code like width: calc(100%/ 6); and it works great.
I had add this rule to #cssmenu ul li

Answer 2

Try this
ul{
display:table;
table-layout: fixed;
width: 100%;
}
li{
display:table-cell;
display: table-cell;
float: none;
}

I hope it works.
