div not extending to bottom
Question
I want to create a layout like this-
Footer is sticky.
Below is the code I tried:
body { position: relative; -moz-user-select: none; -ms-user-select: none; -webkit-user-select: none; user-select: none; } html, body { height: 100%; margin: 0; } .container { max-width: 1280px; margin: 0 auto; } .page-wrap { min-height: 100%; margin-bottom: -45px; background-color: #f2f2f2; } #header { height: 80px; width: 100%; background-color: #fdbb30; position: relative; padding-bottom: 10px; } .adminpanelContainer { background-color: white; padding: 40px; margin-top: 20px; height: 100%; } #footer { width: 100%; background-color: #fff; z-index: 1; } #footerwrapper { height: 45px; }
<body> <div class="page-wrap"> <header id="header"> <div class="container"></div> </header> <div id="body"> <div class="container" style="height:100%;"> <div class="panelContainer"></div> </div> </div> </div> <footer id="footer"> <div class="container" id="footerwrapper"></div> </footer> </body>
I am giving height: 100% to .adminpanelContainer and its ancestors also but there is no effect on it.
I want the white area to expand across the whole web page irrespective of their height.
What changes I have to make to extend the div till bottom.

This will work for you:
I have just added ↓
#body .container{
height: calc(100vh - (90px + 45px));
}
the calculation is as follows:
height: calc(100ViewportHeight - (#header[height+padding-bottom]+ #footerwrapper[height]));

A working Sample from your snippet:
body { position: relative; -moz-user-select: none; -ms-user-select: none; -webkit-user-select: none; user-select: none; } html, body { height: 100%; margin: 0; } .container { max-width: 1280px; margin: 0 auto; } .page-wrap { min-height: 100%; margin-bottom: -45px; background-color: #f2f2f2; } #header { height: 80px; width: 100%; background-color: #fdbb30; position: relative; padding-bottom: 10px; } .adminpanelContainer { background-color: white; padding: 40px; margin-top: 20px; height: 100%; } #footer { width: 100%; background-color: #fff; z-index: 1; } #footerwrapper { height: 45px; } #body .container{ height: calc(100vh - (90px + 45px)); }
<body> <div class="page-wrap"> <header id="header"> <div class="container"> </div> </header> <div id="body"> <div class="container" > <div class="panelContainer"> </div> </div> </div> </div> <footer id="footer"> <div class="container" id="footerwrapper"> </div> </footer> </body>
Hope this was helpful for you.

If you can restruct your HTML, you can easily create this layout using flex :
go full page for better result
* { box-sizing: border-box; } body { margin: 0; display: flex; flex-direction: column; height: 100vh; } header { height: 80px; background-color: #fdbb30; position: relative; padding-bottom: 10px; } footer { height: 45px; background-color: #fff; z-index: 1; } .container { max-width: 1280px; margin: 0 auto; border: 1px solid; } .content { flex: 1; background: red; padding: 20px; } .content>.container { height: 100%; } .adminpanelContainer { background-color: #ccc; padding: 40px; height: 100%; }
<header> <div class="container"> header content </div> </header> <div class="content"> <div class="container"> <div class="adminpanelContainer"> full height content </div> </div> </div> <footer> <div class="container"> footer content </div> </footer>

Without adjusting any existing markup the intended behaviour can be achieved by declaring <percentage> height unit values for applicable nested elements as well.
Start by declaring a relative height (with percentage unit values ) for the element
#body- account for the combinedheightof the nestedheader&footerelements, eg:#body { /* 100% height minus the sum of header & footer height */ height: calc(100% - 125px); }Next, declare
height: 100%for any further nested elements that are required to occupy the full available height of the viewport, eg:.panelContainer { height: 100%; }
The code snippets below demonstrate this behaviour with both fixed and relative footer elements.
Fixed Footer:
body { position: relative; -moz-user-select: none; -ms-user-select: none; -webkit-user-select: none; user-select: none; } html, body { height: 100%; margin: 0; } .container { max-width: 1280px; margin: 0 auto; text-align: center; } .page-wrap { /* adjusted */ height: 100%; background-color: #f2f2f2; } #header { height: 80px; width: 100%; background-color: #fdbb30; position: relative; padding-bottom: 10px; } .adminpanelContainer { background-color: white; padding: 40px; margin-top: 20px; height: 100%; } #footer { width: 100%; background-color: #fff; z-index: 1; /* additional */ position: fixed; bottom: 0; } #footerwrapper { height: 45px; } /* Additional */ * { box-sizing: border-box; } #body { height: calc(100% - 125px); /* 100% height minus the sum of header & footer height */ } .panelContainer { height: 100%; /* following styles added just for the sake of demonstration */ background: white; border: 1px solid #d6d6d6; box-sizing: border-box; max-width: 80%; margin: auto; } .panelContainer .inner { position: relative; height: 100%; } .panelContainer .inner span { position: absolute; top: 0; bottom: 0; left: 0; right: 0; height: 20px; margin: auto; }
<body> <div class="page-wrap"> <header id="header"> <div class="container"> <span>height: 80px</span> </div> </header> <div id="body"> <div class="container" style="height:100%;"> <div class="panelContainer"> <div class="inner"><span>relative height declared with <code>percentage</code> values</span></div> </div> </div> </div> </div> <footer id="footer"> <div class="container" id="footerwrapper"> <div class="container"> <span>height: 45px</span> </div> </div> </footer> </body>
Relative Footer:
body { position: relative; -moz-user-select: none; -ms-user-select: none; -webkit-user-select: none; user-select: none; } html, body { height: 100%; margin: 0; } .container { max-width: 1280px; margin: 0 auto; text-align: center; } .page-wrap { /* adjusted */ height: 100%; background-color: #f2f2f2; } #header { height: 80px; width: 100%; background-color: #fdbb30; position: relative; padding-bottom: 10px; } .adminpanelContainer { background-color: white; padding: 40px; margin-top: 20px; height: 100%; } #footer { width: 100%; background-color: #fff; z-index: 1; /* additional */ position: relative; bottom: 0; } #footerwrapper { height: 45px; } /* Additional */ * { box-sizing: border-box; } body { padding-bottom: 45px; } #body { height: calc(100% - 80px); /* 100% height minus the height of the header */ } .panelContainer { height: 100%; /* following styles added just for the sake of demonstration */ background: white; border: 1px solid #d6d6d6; box-sizing: border-box; max-width: 80%; margin: auto; } .panelContainer .inner { position: relative; height: 100%; } .panelContainer .inner span { position: absolute; top: 0; bottom: 0; left: 0; right: 0; height: 20px; margin: auto; }
<body> <div class="page-wrap"> <header id="header"> <div class="container"> <span>height: 80px</span> </div> </header> <div id="body"> <div class="container" style="height:100%;"> <div class="panelContainer"> <div class="inner"><span>relative height declared with <code>percentage</code> values</span></div> </div> </div> </div> </div> <footer id="footer"> <div class="container" id="footerwrapper"> <div class="container"> <span>height: 45px</span> </div> </div> </footer> </body>
