  • 0

I’m having trouble with some whitespace above my table. I have a table that holds two buttons and then right below it is a Google map. I would like to float the table over top of the map instead of having them listed, if you will. I get about ten pixels of white space and I am having so much trouble figuring out why. Any ideas? Here is the first part of my HTML:

   <body onload="initMap()">
<div>
    <table width="100%"  >
        <tr>
            <th height="45" align="right" bgcolor="#CED0D0"  scope="col">
                <a href = http://search.html class="classname">Search</a> 
                <a href = http://loggedout.html class="classname">Log Out</a>
            </th>
        </tr>
    </table>        
</div>   
<div id="map_canvas" style="float:left; width:100%; height:100%"></div>

    I saved your code and loaded it in chrome and saw the whitespace at the top. Looks to be from the tr, because you have the table set to border-collapse: separate and border-width : 8px and border-spacing set to 2px. spacing + width = 10px.

    So not seeing why you did this (or why you’re using a table at all, honestly), I would add the following:

    table {
    border-width: 0px;
    border-spacing: 0px;
    border-collapse: collapse;
}
