Question

I’m a bit new to css. I’m trying to make a horizontal navigation bar with only 3 text items for mobile device viewing. I have width set to 100% and each section width set to 32% (I tried 33% but it would place the 3rd item on a new line.) It looks ok as it is, but when I hover (or click on using a mobile device) the background color changes and you can see the margins.

ul.nav {
    width:100%;
    margin:0 auto;
    padding:0;
    list-style:none;
    display:inline-block;
    background-color:#62564A;
    text-align:center;
    font-family: sans-serif; 
}

.nav li { 
        display:inline;
    }

.nav a {
    width:33%;
    text-align:center;
    display:inline-block;
    padding-bottom:13px;
    padding-top:12px;
    border-left: 1px solid #fff;
    border-right: 1px solid #fff;
}

.nav a:hover { 
    background:#A26A42;
    border:none;
    width:32%
}

ul.nav li:first-child a{
    border:none;
}
ul.nav li:last-child a {
    border:none;
}

End of CSS

<ul class="nav">
        <li><a href="#">Search</a></li>
        <li><a href="#">Legend</a></li>
        <li><a href="#">Info</a></li>
</ul>
<div id="map_canvas" style="position:absolute;left:0;right:0;"></div>

Thank you for any help.

I’d rework your CSS like this jsFiddle example.

CSS

ul.nav {
    width:100%;
    margin:0 auto;
    padding:0;
    list-style:none;
    background-color:#62564A;
    text-align:center;
    font-family: sans-serif; 
}
.nav li { 
    display:inline-block;
    width:33%;
    margin:0;
    padding:0;
}
.nav a {
    text-align:center;
    padding:12px 0 13px 0;
    margin:0;
    border-left: 1px solid #fff;
    border-right: 1px solid #fff;
    display:block;
}
.nav a:hover { 
    background:#A26A42;
    border:none;
}

ul.nav li:first-child a{
    border:none;
}
ul.nav li:last-child a {
    border:none;
}​
