CSS Panel Assignments

I am attempting to split the screen where 80% is dedicated to displaying a Google map at the bottom, and the remaining 20% displays content in a div with the ID '#data' at the top. However, the code below does not seem to achieve this layout as intended. The adjustments I made are indicated by ** and enclosed in **

<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
    <style type="text/css">
        html { height: 100% }
        body { height: 100%; margin: 0; padding: 0 }
        **#map-canvas { height: 80% }
        #data { height: 20% }**
    </style>
    <script type="text/javascript"
  src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&sensor=SET_TO_TRUE_OR_FALSE">
</script>
<script type="text/javascript">
  function initialize() {
    var mapOptions = {
      center: new google.maps.LatLng(-34.397, 150.644),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map-canvas"),
        mapOptions);
  }
  google.maps.event.addDomListener(window, 'load', initialize);
 </script>
 </head>
 <body>
    **<div id="data"/>**
    <div id="map-canvas"/>
 </body>
 </html>

Any suggestions or solutions for achieving this layout?

Answer №1

To ensure proper rendering of your div elements, consider assigning a height in em units such as 100em or wrapping the two divs in a parent div with specified heights either in em's or pixels. This will provide a clearer context for understanding percentages like 80% and 20%. Additionally, using self-closing tags on div elements is not recommended as it can lead to inconsistent display across browsers. While it may work on some browsers currently, there is no guarantee it will work universally in the future and could potentially cause layout issues.
