Question

All,

I am trying to build a top menu. For some reason, the li elements are not starting from the top of ul, there appears to be a small margin left at the top. Any explanation please.

HTML Code:

    <div id="menu_bars">
    <div id="main_bar">
        <ul>
            <li id="overview_tab" class="maintabs"><a  id="text_overview_tab">Overview</a></li><li id="collar_tab" class="maintabs"><a id="text_collar_tab">Collar/ Neckline</a></li><li class="maintabs" id="body_tab"><a  id="text_body_tab" >Body</a></li><li id="sleeves_tab" class="maintabs"><a id="text_sleeves_tab" >Sleeves</a></li>
        </ul>
    </div>
      </div>

CSS CODE:

html {
height: 100%;
}

body#container {
position: relative;
width: 100%
min-width: 1280px;
height: 100%;
min-height: 700px;
background-color: rgba(255,255,255,0.8);
margin: 0 auto;
}

    #menu_bars {
    position: relative;
    width: 90%;
    height: 20%;
    margin: 0 auto;
}
        #main_bar {
        float: left;
        width: 78%;
        height: 100%;
    }
    #main_bar ul {
        float: left;
        width: 100%;
        height: 100%;

                }

Your <li> elements are set to display: inline-block, but their vertical-align property defaults to baseline. Specify this in your CSS:

#main_bar li {vertical-align: top}
