Problem with a header

[hinde]

I am new to CSS and my html is rusty as hell, and I want to have links arranged horizontally on the top of my page. They are block links.

CSS script: 

a.blue_top_tab {
text-align: center; 
display: block; 
background: blue; 
color: black; 
text-decoration: none; 
width: 120px;
font-size: 140%; 
padding-top: 10px;
padding-bottom: 10px;
}

And here is my link:

<a class="blue_top_tab" href="other.html">Start</a>

Now when I have multiple block links they always move below the previous one. I know I could just align it using top and left, but I would like to know why its stacking top to bottom and not right to left. Edit: Can CSS blocks stack left to right?

You need to use display:inline; to get lists to line up horizontally. Lists rock for menus. :)
