Hello everyone, I have small problem ...
I created a fixed topbar within which I have added two links to the left (home and forums) and on the right I added the login box / UserCP (and so far so good)
My problem is that I wish the bar was full screen but that elements within start and end at the edges of my template (in this case I created a template of fixed 1000px centered)

Public for completeness my additional.css where there is the topbar

PHP Code:

.Topbar {
    position: fixed !important;
    top: 0px;
    left: 0px;
        background: #393939; /* Old browsers */
/* IE9 SVG, needs conditional override of 'filter' to 'none' */
background: url(data:image/svg+xml;base64,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);

        line-height: 40px;
        overflow: hidden;
        position: fixed;
    height: 40px;
    width: 100%;
       font: bebasneue;
/* Specifico l'ordine si sovrapposizione della topbar */
    z-index: 9999;
}

.Topbar li {
    display: inline;
    margin: 10px 10px;
    margin-bottom: 0px;
    line-height: 10px;
}


.Topbar {
    overflow: visible;
}
