Vertical menu and a Horizontal menu tag conflict

[davidhelp]

I would like to have both a Vertical menu and a Horizontal menu on the same page.

The two have a similiar layout with ui and li etc.

Question: How to have them not conflict?

Example below. Do you add a name like ul.menu

Not sure how to ask the question  : )

Horizontal Navigation Bar

ul {
list-style-type: none;
}

li a {
display: block;
}

li {
float: left;
}

li a:hover {
background-color: #111;
}

-------------------------------------

Vertical Navigation Bar

ul {
list-style-type: none;
}

li a {
display: block;
}

li {
text-align: center;
}

li:last-child {
border-bottom: none;
}

li a.active {
background-color: #4CAF50;
color: white;
}

li a:hover:not(.active) {
background-color: #555;
color: white;
}

========================================

<ul>
<li><a class="active" href="#home">Home</a></li>
<li><a href="#news">Menu</a></li>
<li><a href="#contact">Menu</a></li>
<li><a href="#about">Menu</a></li>
</ul>

I think I found the answer.
 As an example I could add a class then a name in front of the tag as seen below.

So I could say .horizontal ul or .vertical ul etc. Any name to tell them apart.

.menu ul {
	list-style-type: none;
	padding: 0;
	margin: 0;
}
.menu li {
	float: left;
	position: relative;
}
.menu a {
	display: block;
	font-size: 100%;
	width: 130px;
	color: #000;
	text-decoration: none;
	text-align: left;
	font-family: Georgia, "Times New Roman", Times, serif;
	font-weight: bold;
	padding-top: 5px;
	padding-right: 5px;
	padding-bottom: 5px;
	padding-left: 50px;
	background-color: #D1D1D1;
}
.menu :visited {
}
.menu :hover {
	color: #FFF;
	background: #D14B34;
}
.menu ul ul {
	visibility: hidden;
	position: absolute;
	width: 130px;
	height: 0;
}
.menu ul li:hover ul, .menu ul a:hover ul {
	visibility: visible;
}

-----------------------------------------------------

<div class="menu">
<ul>
<li><a href="#">Dropdown</a></a>
<ul>
<li><a href="#">Menu</a></li>
<li><a href="#">Dropdown</a></li>
<li><a href="#">Menu</a></li>
</ul>
</li>
<li><a href="#">Menu 1</a></a>
<ul>
<li><a href="#" title="Dropdown">Dropdown</a></li>
<li><a href="#" title="Menu">Menu</a></li>
<li><a href="#" title="Dropdown">Dropdown</a></li>
<li><a href="#" title="Menu">Menu</a></li>
</ul>
</li>
<li><a href="#">Menu 2</a></a>
<ul>
<li><a href="#">Menu</a></li>
<li><a href="#">Dropdown</a></li>
<li><a href="#">Menu</a></li>
</ul>
</li>
<li><a href="#">Menu 3</a></a>
<ul>
<li><a href="#">Menu</a></li>
<li><a href="#">Dropdown</a></li>
<li><a href="#">Menu</a></li>
</ul>
</li>
</ul>
</div>

Or use a unique ID.

CSS
=====
#vert ul {list-style-type: none;}
#vert li {text-align: center;}
#vert li:last-child {border-bottom: none;}
#vert li a {display: block;}
#vert li a.hover, #vert li a.active, #vert li a.focus {
    background-color: #4CAF50;
    color: #FFF;
}

HTML
=====
<ul id="vert>
<li><a class="active" href="#home">Home</a></li>
<li><a href="#news">News</a></li>
<li><a href="#contact">Contact</a></li>
<li><a href="#about">About</a></li>
</ul>

Do test your navigation on actual touch screen devices.  I mention this because without a mouse, HOVER doesn't do anything.  The prevailing wisdom in responsive web design is to keep navigation simple and mobile-friendly.

Thanks.

I tried googling this but did not know how to state the question. I mostly got how to create menus of one or the other but not both.

Also this will help when creating lists that use the same <li> <ul>

Responsive Hamburger Menu.  Everything must work on click/tap with an average adult finger tip.

Thanks again. I like that menu as when you make the screen smaller you see a 3 line button that when clicked on you see the menu items.
