Align Nav bar to right - html

Question

Hi I have this navbar and wondering how to alight it to the right.
I've tried float:right but doesn't work. Also tried div align but not working
as well. I'm new to css though.
<div align="right">
<ul id="menu">
<li>Home</li>
<li>
About ￬
<ul class="hidden">
<li>Who We Are</li>
<li>What We Do</li>
</ul>
</li>
</ul>
</div>

Answer 1

The align="right" attribute is deprecated. Don't use it!
Either remove the absolute positioning on the ul element, and then float the element to the right, or add right: 0.
Updated Example
<div>
<ul id="menu">
<li>Home</li>
<li>
About ￬
<ul class="hidden">
<li>Who We Are</li>
<li>What We Do</li>
</ul>
</li>
</ul>
</div>
ul {
list-style-type: none;
margin: 0;
padding: 0;
float: right;
}
li {
display: inline-block;
float: right;
margin-right: 1px;
}
li a {
display: block;
min-width: 140px;
height: 50px;
text-align: center;
line-height: 50px;
font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
color: #fff;
background: #2f3036;
text-decoration: none;
}
li:hover a {
background: #19c589;
}
li:hover ul a {
background: #f3f3f3;
color: #2f3036;
height: 40px;
line-height: 40px;
}
li:hover ul a:hover {
background: #19c589;
color: #fff;
}
li ul {
display: none;
}
li ul li {
display: block;
float: none;
}
li ul li a {
width: auto;
min-width: 100px;
padding: 0 20px;
}
ul li a:hover + .hidden, .hidden:hover {
display: block;
}
input[type=checkbox] {
display: none;
}
input[type=checkbox]:checked ~ #menu {
display: block;
}
#media screen and (max-width : 760px) {
ul {
position: static;
display: none;
}
li {
margin-bottom: 1px;
}
ul li, li a {
width: 100%;
}
.show-menu {
display: block;
}
}

Found an answer on my position: relative not absolute

Answer 3

You need to add "width: 100%" in file css.
Code:
ul {
list-style-type:none;
margin:0;
padding:0;
position: absolute;
width: 100%;
}
