CSS stretch horizontal menu to fill all width

Question

Here is the link to my site. When you have a wide resolution there is no issue with the dispaly, but if with the brower I try to simulate a little resolution, I come across an issue : The nav bar won't fill the entire page but only the width of the browser, even though I used width : 100%;

Here the code in CSS

header {
width: 100%;
/*min-width: 1000px;*/
-webkit-box-shadow: 0px 1px 1px 0px rgba(250, 250, 250, .5);
-moz-box-shadow: 0px 1px 1px 0px rgba(250, 250, 250, .5);
box-shadow: 0px 1px 1px 0px rgba(250, 250, 250, .5);
padding-top: 60px; /* Gere l'espace entre le top et la barre de menu */
background: url('../img/binding_dark.png');
}

nav {
margin-bottom: 30px;
width: 100%;

background: -moz-linear-gradient(top, #353535 0%, #222222 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#353535), color-stop(100%,#222222));
background: -webkit-linear-gradient(top, #353535 0%,#222222 100%);
background: -o-linear-gradient(top, #353535 0%,#222222 100%);
background: -ms-linear-gradient(top, #353535 0%,#222222 100%);
background: linear-gradient(top, #353535 0%,#222222 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#353535', endColorstr='#222222',GradientType=0 );
border-width: 1px 0 1px 0;
border-style: solid;
border-color: #000;
}

The header is the wide black block and the nav is inside it.

Here is an exemple of the issue:

The header won't fill all the page (horizontally), the li element would overflow, and gradient background would split.

Is there a solution to this please ?

Answer 1

Try increasing the width of the nav ul.

nav ul {
width: 809px;
height: 45px;
margin: 0 auto;
border-left: 1px solid #111;
border-right: 1px solid #444;
}

You can use Developer Tools(F12) to inspect elements.

Here is your corrected css and fiddle link

header {
    width: 100%;
    -webkit-box-shadow: 0px 1px 1px 0px rgba(250, 250, 250, .5);
    -moz-box-shadow: 0px 1px 1px 0px rgba(250, 250, 250, .5);
    box-shadow: 0px 1px 1px 0px rgba(250, 250, 250, .5);
    padding-top: 60px; /* Gere l'espace entre le top et la barre de menu */
    background: url('../img/binding_dark.png');
}

hgroup,
main,
nav {
    margin-bottom: 30px;
    width: 100%;
    background: -moz-linear-gradient(top, #353535 0%, #222222 100%);

Answer 3

There are other issues with the layout, but for the immediate problem, you could try

#page-wrap header {min-width: 1400px;}
