Convert a vertical menu to horizontal in CSS - html

Question

I am using a menu and I am trying to change the way it looks. I want the submenus (ul li) to be horizontal and not vertical. I tried everything on CSS like adding float but nothing worked.
I am using this HTML code :
<div id='cssmenu'>
<ul>
<li class='active'><a href='#'>Home</a></li>
<li class='has-sub'><a href='#'>Page2</a>
<ul>
<li><a href='#'>Page1</a></li>
<li><a href='#'>Page3</a></li>
<li class='last'><a href='#'>Page4</a></li>
</ul>
</li>
<li class='has-sub'><a href='#'>About</a>
<ul>
<li><a href='#'>YOLO</a></li>
<li class='last'><a href='#'>Contact</a></li>
</ul>
</li>
<li class='last'><a href='#'>Contact</a></li>
</ul>
</div>
I am using this CSS code :
#cssmenu > ul {
background: url(images/highlight-bg.png) repeat;
padding-bottom: 3px;
font-family: 'Open Sans', sans-serif;
font-weight: 600;
}

#cssmenu > ul:before,
#cssmenu > ul:after {

#cssmenu:after,
#cssmenu > ul:after {

}
#cssmenu {

#cssmenu > ul {
