JQuery-Mobile content area 100% height between head and foot
A lot of topics on this... but not getting the point how to do it.
I have my JQM Header and Footer. I want the content area to fill the 100% height in between head and foot.
Thats my code, how is it possible?
<body>
<div data-role="page" id="entryPage" data-theme="d">
<div data-role="header" id="header" data-position="fixed" data-theme="d">
<h1>Page Title</h1>
</div><!-- /header -->
<div data-role="content" id="content" data-theme="d">
<div id="columnwrapper">
<div id="leftcolumn">
<div class="innertube">
Point 1
</div>
<div class="innertube">
Point 1
</div>
</div>
</div>
<div id="rightcolumn">
<div class="innertube">
<div id="switch1">
test
</div>
</div>
<div class="innertube">
test2
</div>
</div>
<div id="contentcolumn">
<div class="innertube">Content</div>
<div class="innertube">Content</div>
</div>
</div><!-- /content -->
<div data-role="footer" id="footer" data-position="fixed" data-theme="d">
<div id="switch2">
<a href="#foo" data-role="button" data-icon="arrow-u">Expand main menu</a>
</div>
</div><!-- /footer -->
</div><!-- /page -->
</body>
CSS:
#columnwrapper{
float: left;
width: 100%;
margin-left: -75%; /*Set left margin to -(contentcolumnWidth)*/
background-color: #C8FC98;
}
#leftcolumn{
margin: 0 40px 0 75%; /*Set margin to 0 (rightcolumnWidth) 0 (contentcolumnWidth)*/
background: #C8FC98;
}
#rightcolumn{
float: left;
width: 40px; /*Width of right column*/
margin-left: -40px; /*Set left margin to -(RightColumnWidth)*/
background: yellowgreen;
}
#contentcolumn{
float: left;
width: 75%; /*Width of content column*/
background-color: blue;
}
.innertube{
margin: 0px; /*Margins for inner DIV inside each column (to provide padding)*/
margin-top: 0;
}
Actually the inner area only fills the height depending on the content... means 2 divs 2 rows, but not 100%..
Thanks

The CSS position: fixed doesn't work correctly in mobile browsers. My experience is with Android and iOS browsers and none of them impliment position: fixed properly (the exception is the iOS 5 browser but it's still in beta).
Rather than fixing an element to the screen and not moving it when the user scrolls in mobile browsers it tends to be treated like position: absolute and it moves when the page scrolls.
Also using the CSS overflow property won't allow scrolling on most mobile devices (iOS supports it but the user has to know to use two fingers while scrolling in a scrollable-div).
You can however use CSS but be aware you will need to use position: absolute or you can use JavaScript to set the heights on the elements.
Here is a jQuery Mobile solution using JavaScript to set the heights of the pseudo-page elements:
$(document).delegate('#page_name', 'pageshow', function () {
var the_height = ($(window).height() - $(this).find('[data-role="header"]').height() - $(this).find('[data-role="footer"]').height());
$(this).height($(window).height()).find('[data-role="content"]').height(the_height);
});
To get a flawless finish you need to take into consideration the behavior of the target device's address bar because if you want a fullscreen webpage then you have to add the height of the address bar to the height of the page.
