I'm trying to design a web page these days that is a bit hard.
I have three main divs. First one for header, another for footer, and third one for main content. Header and footer must be fixed in top and bottom of the page. Their place mustn't change with resizing of browser window. Third div must be in the blank space between those divs. It can resize to fit the page with window resize.
Height of main div must exactly change, because I want to place a Google Maps in that div, so the height of this div is important.
I tried so many things, but they were not successful. Setting height of the div to 100%(while height of body and html is 100%, too) was not the answer. Using a table (with three rows, two rows with fixed height, one row with variable height, with height="100%") had some problems, too(in IE8, when I declared a doctype, the div in second row (with height:100%) didn't fit the cell anymore!).
Now I have no idea to do this work. What can I do?
Note: I prefer not to use CSS3, because compatibility with old browsers is important for me.
You could try something like this.
HTML
<div id="header"></div>
<div id="body"></div>
<div id="footer"></div>
CSS
#header {
height:50px;
width: 100%;
background: black;
position: fixed;
z-index: 1;
top: 0;
}
#body {
height:100%;
width: 100%;
background: #CCC;
position: absolute;
z-index: 0;
}
#footer {
height: 50px;
width: 100%;
background: #0CF;
position: fixed;
bottom: 0;
}
Here is a fiddle - http://jsfiddle.net/6M59T/
Use a set height for your header, and use sticky footer to keep your footer a set height and aligned to the bottom as well. The space in between should then always be the right height.
You should try the well known Clearfix hack to handle height issues, because you need to "clear" parents elements to get that full 100% height you need.
This is one of the shortcomings of css. You cannot accomplish what you want using just those three divs. You need to use additional divs to offset the height of your header and footer. Here is how to solve this:
<body style="height:100%; margin:0; padding:0;">
<div id="header" style="height:50px; position: relative; z-index: inherit; background-color:lightblue;"></div>
<div id="content" style="height:100%; margin:-50px 0 -70px 0; background-color:wheat">
<div id="header-offset" style="height:50px;"></div>
<div id="footer-offset" style="height:70px;"></div>
</div>
<div id="footer" style="height:70px; background-color:lightblue;"></div>
</body>

So I have a div that i want to position at the bottom of my page, with the body of the div completely hidden below the user's viewport, except the entirety of a header which is fixed to the bottom of the page.
Contraints:
The height of the entire div is dynamic, as there can be any number of items in there
The header of the div is contained entirely within the div, syntax-wise
Ideally I'd like to do this completely with CSS, but if a little bit of JavaScript is needed, that's fine too.
Any ideas on how this can be done? position: fixed and bottom: (height of header - height of div) doesn't work because the height of the div changes when you resize the viewport.
Figured it out. Here's my solution. The key is to have a wrapper that is the same height as the header that you want sticking out, and apply position fixed and bottom 0 to that parent wrapper.
html
<html>
<body>
<div class="wrapper">
<div class="wrapper-top">
</div>
<div class="wrapper-bottom">
This can be variable height
<div>
</div>
</body>
</html>
css
.wrapper {
height: 50px;
position: fixed;
bottom: 0;
width: 100%;
}
.wrapper-top {
height: 50px;
width: 100%;
}
I have been banging my head against the wall trying to figure out this problem and I have looked high and low for the answer and came up with similar results.
Synopsis
The problem is that I am building a website using the 960 grid and have three columns that I want to stretch at 100% at all times. Here is a fiddle for your reference: http://jsfiddle.net/Uec7h/1/
Essentially the html is like so:
<div class="contentWrapper">
<div class="container_12">
<div class="grid_2 leftSide clearfix">
Left sidebar content.
</div>
<div class="grid_7 content">
Lots of content loaded from the server.
</div>
<div class="grid_3 rightSide">
Right sidebar content.
</div>
</div>
</div>
with the CSS being like
html, body {
height: 100%;
}
.content {
height: 100%;
}
.leftSide {
height: 100%;
background-color: #000000;
}
.rightSide {
height: 100%;
background-color: #000000;
}
.contentWrapper {
height: 100%;
}
The fiddle isn't completely accurate to what I am seeing on my local version, but it's close. Seems like the left and right sidebars do not want to expand to 100% no matter what I do.
What I've Tried
Most of the answers I have found on SO have suggested to put height: 100% on the html, body elements and everything should work out fine. Adding this attribute and giving both sidebars height: 100% did work a little bit, but if the content in the middle column gets too big, it stops at a certain point and won't continue to stretch.
I have tried adding the clearfix class that comes with the 960 grid but it didn't seem to help at all.
Question
How do I get the left and right side bars height in the fiddle to be 100% no matter what content is in the middle column?
If you add the following CSS to the sidebar elements it will fill the 100% of the height.
display:block;
height:auto;
position:absolute;
top:0px;
bottom:0px;
If you place the sidebar into a wrapper div with relative positioning, the content section will be again in it's right place...
I would also set padding and margin to 0 for the body.
EDIT:
If you add height: 100% to the .container_12 it will get a real height, and children elements can have a 100% height. Notice that the sidebars will be as height as the window itself, but your content at the middle can be taller than 100%... Fiddle
Dont know the 960 grid, the EDITED solution - using visibility: visible; -
HTML
<div id="box">
<div class="vision"> sdfsdfsd </div>
</div>
CSS
#box {
float: left;
border: 2px solid red;
}
.vision {
width: 300px;
height: 600px;
visibility: visible;
}
I have a layout where I need to use height: 100% on html and body (and any wrapper divs I resort to using) to achieve an effect similar to pages, so that the content on my first "page" is centred, scrolling down the content on the second "page" is centred etc.
The html looks like this:
<section class="page" id="p01">
<div class="spacer">
</div>
<div class="outer">
<div class="inner">
Some content
</div>
<div class="inner">
Some content
</div>
</div>
</section>
<section class="page" id="p02">
<div class="spacer">
</div>
<div class="outer">
<div class="inner">
Some content
</div>
<div class="inner">
Some content
</div>
</div>
</section>
and the vertical centring etc. achieved with this styling:
body, .page {height: 100%; margin: 0 auto;}
.spacer {
float: left;
height: 50%;
margin-bottom: -150px;
}
.outer {
height: 300px;
width: 100%;
background-color: #fca;
clear: both;
position: relative;
display: block;
white-space: nowrap;
}
.inner {
width: 41%;
margin: 0 6%;
height: 300px;
background-color: green;
display: inline-block;
vertical-align: middle;
white-space: normal;
}
.inner:first-child {
margin-right: 0;
}
You can see it at work in this fiddle:
http://jsfiddle.net/terraling/3V5rV/
The problem is the body background (here I'm just using color, but on my site it will be an image) leaks out into the body margins, i.e. the body content has a max-width and should be centred with white margins.
I can fix that either by... setting html background-color to white, as per
http://jsfiddle.net/terraling/yM53t/
...but body background becomes cutoff when scrolling into the second page (that wasn't a problem in the first fiddle).
Alternatively I could set the background image on a wrapper div and not on the body. That solves the problem of it leaking into the body margins, but it still has the same problem that it is cut off on scrolling.
(see: http://jsfiddle.net/terraling/3V5rV/1/ )
Any solution that involves removing the height: 100% declaration from any of html, body or wrapper collapses the layout (including replacing with max-height: 100%).
There's a whole lot of problems with this construct and not all of them can be solved, unfortunately.
The background issue
As you have seen yourself the background of body extends to the viewport if html does not have a background. That's solvable.
The float issue
When an element floats it does not contribute to the height of its parent element. So they don't grow (e.g. body does not expand). That can be solved if you can use alternatives. For vertically centering an element you could use display: table-cell e.g., which allows you to vertically center the content.
The height issue
This is where all hope is gone. height: 100% refers to the height of the parent, of course. The parent of body is html which in turn is the child of the viewport. You gave html the size of 100% (= the size of the viewport) and body the size of 100% (= size of html = size of viewport).
So now body has a fixed height and it can't expand meaning the background doesn't expand as well. Now one might have the idea to give body no size so that it can expand. But .page has 100% too. If a parent (in this case body) has no fixed size 100% has no meaning and will be treated as auto, which means as big as the content. And the content has a height of 300px. So the .page elements wouild no longer have the height of the viewport but 300px.
As for the collapse of the CSS, you should either specify the height specifically height:200px; or add padding to the bottom/top of the page so that the content wraps. You can also use min-height:200px; then add the margin-bottom:20px; to separate the pages. I would approach this at a specific height with the wrapper having the specific background-image and bottom-margin.
In order to center your background-image to the <html> you can specify the position as 50%.
This can be done by doing background:url('yourimage.jpg') repeat 0 50%;This will ensure the background is centered.
Just wondering how to style a header like the attached image. Was thinking of using two divs, the left for the text and the right for the horizontal repeating image. Problem is I need the right div's width to change with respect to different header lengths.
Any help would be appreciated!
header image
You can do that in simple;
.header{
width:100%;
height:20px;
background:url('http://jsfiddle.net/favicon.png') repeat;
}
.header span{
background-color:#FFF;
display:inline-block;
height: 20px;
}
<div class="header"><span class="title">Header Text</span></div>
You can include this in various pages and the title space re-size accordingly.
Here is a working Live Demo
Use left and right DIVs with respective width and then to the right div use text-align: right; property so that the content loaded in right div will remain to right and increase to left depending on the size of content
<div class="header">
<div class="left"></div>
<div class="right"></div>
</div>
.header{overflow: hidden;} //Considering width: 1000px;
.left{float: left; width: 100px;}
.right{float: right; width: 900px; text-align: right;}
you could do it with just a <h1> tag for semantic reasons, and ad a background-image to it.
With padding-right you now can control the amount of how many times it should repeat itself and filling up the needed space.
i am trying to code an html with 2 divs inside a div.
There is a parent div with no width or height.. the width is the browser width and the height is not specified.
I want inside this parent div, 2 divs: 1st one needs to have a width or 250px and the 2nd one needs to have the rest of the screen's width. They both are missing the height.. depending how much content there will be inside it.
Now i was trying to make it like this:
<div id="calendar">
<section id="list">
</section>
<section id="grid">
</section>
</div>
and the css like this:
#calendar {
margin: 0 auto;
position: relative;
overflow: hidden;
}
#calendar #list {
background: #f00;
position: absolute;
width: 250px;
left: 0;
top: 0;
}
#calendar #grid {
background: #0f0;
position: absolute;
left: 250px;
top: 0;
right: 0;
}
now the problem is, the parent div doesnt resize when i add content to the children divs
I hope there is a workaround with the CSS to solve this cause it would be bad to do it via JS.
Thank you in advance,
Daniel!
Here's my solution -> http://tinkerbin.com/Z8mJmItU
Float the #list with its given width, then give #grid the same margin-left.
Then to get both columns to look like they have 100% of the height of the parent-container you need an image. Before you'd have to use an 'actual image'. Today you can simply rely on css3 gradients for backgrounds making your page load faster (1 less http request for the image). It may seem more complicated, but it actually isn't 'that' complicated. It even ends up giving you more flexibility since you can change the width and color of the columns without needing to create a new image. All you need is to change the css.
You need to specify a height if you are going to use absolute. Then it should work.
EDIT
use
position: relative;
on the child elements.
EDIT 2
Perhaps this post would help with what you are after? Div width 100% minus fixed amount of pixels
Don't use positioning, use float ... with your current method the parent will collapse and the only way to determine the required height of the parent, would be to calculate the height of the highest child element (typically, with JavaScript).
<div id="calendar">
<section id="list">
</section>
<section id="grid">
</section>
<div class="clear"></div>
</div>
... and the CSS ...
#calendar {
margin: 0 auto;
position: relative;
}
#calendar #list {
background: #f00;
float:left;
width: 250px;
}
#calendar #grid {
background: #0f0;
margin-left: 250px;
}
.clear{
clear:both;
}
This way the #calendar will adjust in height to the tallest child element. Also remember to remove the overflow rule.
... the above for the sake of being brief, you should probably look at using clearfix (by adding a class to #calendar) - read more here.
