I need this because I want to make a menu (which is made from a HTML list) appear horizontally.
I prefer not to use absolute positioning since it might become messy when I start changing the layout of the page.
I would like also to remove the indenting of the sub-lists. Is it possible?
You will have to use something like below
#menu ul{
list-style: none;
}
#menu li{
display: inline;
}
<div id="menu">
<ul>
<li>First menu item</li>
<li>Second menu item</li>
<li>Third menu item</li>
</ul>
</div>
