I want to make a menu that always leaves the items with proportional sizes, occupying all available width and adapting.
.top-menu ul {
width: 100%;
}
.top-menu ul li {
display: inline;
list-style: none;
}
.top-menu ul li a {
display: inline-block;
}
<div class="top-menu full">
<ul>
<li><a>Home</a></li>
<li><a>Aqui!</a></li>
<li><a>Alí!</a></li>
<li><a>Acolá!</a></li>
<li><a>Mais Pra lá</a></li>
<li><a>Não sei onde</a></li>
</ul>
</div>
