Question

The problem is that I placed a horizontal menu bar on my site that fits the whole screen or page so when I tried resizing and making the menu bar smaller to make the size the same with the other parts on the site, everytime I zoom in and out the page, the menu bar resizes unproportionally with the other parts.

To see the problem for yourself, please check my site at http://thenativeisodrafts.tumblr.com and try zooming in and out the page.

Thank you very much!

Here’s the CSS:

#cssmenu ul {
    margin: 0;
    padding: 0;
}
#cssmenu li {
    margin: 0;
    padding: 0;
}
#cssmenu a {
    margin: 0px;
    padding: 0px;
}
#cssmenu ul {
    list-style: none;
}
#cssmenu a {
    text-decoration: none;
}
#cssmenu {
    height: 70px;
    background-color: rgb(35,35,35);
    border-bottom: 5px solid #cd2c23;
    border-top: 5px solid #cd2c23;
    position:absolute;
    right:241px;
    z-index: 1000;
}
#cssmenu > ul > li {
    float: left;
    margin-left: 15px;
    position: relative;
}
#cssmenu > ul > li > a {

    visibility: visible;
}
#cssmenu > ul > li > ul:before {
    content: '';
    display: block;
    border-color: transparent transparent rgb(250,250,250) transparent;
    border-style: solid;
    border-width: 10px;
    position: absolute;

}
#cssmenu > ul ul > li {

    font-family: Verdana, 'Lucida Grande';
    font-size: 13px;

}
#cssmenu ul ul ul {

    position: absolute;
    top: -16px;

    background-color: rgb(250,250,250);

    box-shadow: 0px 1px 3px rgba(0,0,0,.4);
}

Here’s the HTML codes:

<div id='cssmenu' style="width:940.5px; margin:auto">
<ul>
   <li class='active '><a href='index.html'><span>Home</span></a></li>
   <li class='has-sub '><a href='#'><span>Products</span></a>
      <ul>
         <li class='has-sub '><a href='#'><span>Product 1</span></a>
            <ul>
               <li><a href='#'><span>Sub Item</span></a></li>
               <li><a href='#'><span>Sub Item</span></a></li>
            </ul>
         </li>
         <li class='has-sub '><a href='#'><span>Product 2</span></a>
            <ul>
               <li><a href='#'><span>Sub Item</span></a></li>
               <li><a href='#'><span>Sub Item</span></a></li>
            </ul>
         </li>
      </ul>
   </li>
   <li><a href='#'><span>About</span></a></li>
   <li><a href='#'><span>Contact</span></a></li>
</ul>
</div>

The problem is #cssmenu has position: absolute declared on it. Remove this and you should be golden:

#cssmenu {
    height: 70px;
    background-color: #232323;
    border-bottom: 5px solid #CD2C23;
    border-top: 5px solid #CD2C23;
    // position: absolute; // Remove this
    // right: 241px; // And this
}
