css trouble with centering a horizontal unordered list

[code4arab]

I have had trouble centering the unordered list I am using for my navigation. I have looked at other advice and tried to fix it so now my code is a hot mess. I cannot figure out for the life of me what is going wrong. All the solutions I have tried still do not center the list in the window. adding the overflow:visable stretch it out but not 100% and it does not expand when the window grows. \[code\]#navbar {position: fixed;top:-17px;margin-bottom: 10px;font-family:Verdana, Geneva, sans-serif;margin: 0;padding: 0;\[/code\]}\[code\]#navbar ul > li {display: inline-block; float: none;color:white;font-size: 14px;margin-right: 35px;margin-left: 35px;padding: .2em 1em;overflow:visible;\[/code\]}
