在navbar下减去导航栏高度填充整个容器

问题描述

在设有Twitter Bootstrap并使用导航栏的页面上,我想使用Google地图地图填充导航栏下方的整个容器。

On a page styled with Twitter Bootstrap and using the navbar I wanted to fill the whole container below the navigation bar with a Google Maps map. To accomplish that I have added the CSS following below.

我定义了 html body 元素的大小设置为100%,以便用于地图的大小定义。然而,这个解决方案产生一个问题:

I define for the html and body elements the sizes to 100% so that this is used for the map's size definition. This solution, however, yields one problem:

地图的高度现在与整个页面高度相同,这导致一个滚动条,我可以滚动40px导航栏添加。如何将地图大小设置为导航栏的 100% - 40px

The map's height is now the same as the whole page height, which results in a scroll bar which I can scroll for the 40px the navigation bar adds. How can I set the size of the map to 100% - 40px of the navigation bar?

#map {
        height: 100%;
        width: 100%;
}

#map img {
        max-width: none;
}

html, body {
        height: 100%;
        width: 100%;
}

.fill {
        height: 100%;
        width: 100%;
}

.navbar {
        margin-bottom: 0;
}

为了完整性,HTML:

For completeness the HTML:

<!DOCTYPE html>
<html lang="en">
        <head>
                <meta http-equiv="Content-Type" content="text/html;charset=utf-8">
                <!-- Stylesheets -->
                <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
                <link rel="stylesheet" type="text/css" href="css/core.css">
        </head>
        <body>
                <div class="navbar">
                        <div class="navbar-inner">
                        </div>
                </div>
                <div class="container fill">
                        <div id="map">
                        </div>
                </div>
        </body>
</html>


推荐答案

您可以解决绝对定位的问题。 p>

You could solve the problem with absolute positioning.

.fill {
    top: 40px;
    left: 0;
    right: 0;
    bottom: 0;
    position: absolute;
    width: auto;
    height: auto;
}

Demo (jsfiddle)

您也可以使navbar .navbar-fixed-top 并以某种方式在 #map 元素中添加填充或边距。

You could also make the navbar .navbar-fixed-top and somehow add a padding or margin inside the #map element.
