I have next html:
<div class="left">
<div style="margin: 32px 0;">
<div class="border"></div>
</div>
</div>
and css:
.left {
position:absolute;
background: red;
height: 50%;
width: 32px;
}
.border {
background: green;
height: 100%;
}
but I don't see green box :(
UPD: I want to see red squares over and under green box.
UPD2: height of green box should be red.height - 32px*2
Your problem is that you have 3 empty div's here and not one of them has a set height. So even if you do min-height: 100% its not going to work unless some outer container has a height that your not showing. You will need to put some content in there or give one of the 3 div's (assuming they are the only containers on the page) an actual height. Like .left{ height: #px; } (# = the height you want it to have). Otherwise the browser does not know how to render percentages because it has nothing to relate them too.
Div's are block level elements which means they will assume the size of content put in them but if there is no content in them they will assume a height of 0px by 0px.
http://jsfiddle.net/X6qkL/5/ updated
The second div is not assigned a height, so the innermost div cannot be assigned a relative height. Try adding the following CSS rule:
.left div {
height: 100%;
}
Or, assign explicit heights to the inner divs.
http://jsfiddle.net/B9z92/1/
Use min-height: 100%; in .border{...}. and add a class
.middle {
height: 100%;
} and assign it to the parent div of .border{...} div.

Look at this jsfiddle:
http://jsfiddle.net/w9k2sz52/
#content {
background: #ff0000;
min-height: 200px;
}
.container-fluid {
min-width: 2000px;
}
<div id="content">
<div class="container-fluid">
<div class="row">
<div class="col-xs-12">
<h1>Some title here</h1>
</div>
</div>
</div>
</div>
Why is the width of #content not stretching to be 2000px instead of being the width of the viewport? What do I need to do to make content stretch so that no matter what min-width is set on container-fluid #content will always stretch to fit it
Set #content to inline-block, and then set min-width to 100%. Note that setting width to 100% won't have the desired affect.
#content {
background: #ff0000;
min-height: 200px;
min-width: 100%;
display:inline-block;
}
Adding a float will make the parent element the same width as the child:
#content {
background: #ff0000;
min-height: 200px;
float: left;
}
#content {
background: #ff0000;
min-height: 200px;
display: inline-block;
}
You could use
width:auto;
This should mean it stretches to the width of its contents.
EDIT:
The min-width property in CSS is used to set the minimum width of a specified element. The min-width property always overrides the width property whether followed before or after width in your declaration. Authors may use any of the length values as long as they are a positive value.
You need to set a max-width or width with it. Say you had a width of 80% and a min width of 400px, it will be no smaller then 400px even if 80% of the page is 200px.
You could give the content a min width forcing the div to be auto and be no smaller then the content.
Could #content determine the width, while .container-fluid expands to fill it? Instead of the other way around.
#content {
background: #ff0000;
min-height: 200px;
width:2000px;
}
.container-fluid {
width: 100%;
}
By adding
position:absolute
to your CSS declaration for #content, you force the CSS interpreter to check what elements are inside #content, therefore achieving desired effect.
The problem with absolute positionning is that it remove the element from the natural workflow of the document. Therefore, you are better wrapping the element unto which you want to apply absolute positionning inside another element. This one will stay in the natural workflow of the DOM.

I am specifying a background color for the body which displays up to a certain distance only. I need it to be full height and for its child elements too. One of its child elements has border-right which also needs to show over the full screen height.
My CSS looks like(sample one) better check my demo
demo page
html,body {
height: 100%;
background-color: #fefefe;
}
.cover {
height: 100%;
}
.left_side {
float: left;
height: 100%;
border-left: 1px solid #ccc;
width: 31%;
}
and html is
<body>
<div class="cover">
<div class="left_side">
</div>
</div>
</body>
and the bgcolor and childs border seems up-to some limited distance only like
what is that problem guys i need that background and border as 100% height.
Remove height:100% from your body and html style.
Instead of having a border set to the left container, try setting the border on the content container instead.
your css would be something like:
.large-9 .columns .right_side{border-left:1px solid #333;}
the left column is currently set to 100% and renders correctly. the problem is that it doesnt take into account the overflow content you cannot see, until you scroll. The other solution would be to absolute or fixed position the left container, and set its top and bottom values to 0.
css for that would be something like:
.left_side .full_height{position:fixed;top:0;bottom:0;width:200px;}
Here's a really basic layout with a fixed left column - http://jsfiddle.net/WAJtk/
and a version with a fixed header too - http://jsfiddle.net/WAJtk/1/

You could use absolute position and setting top and bottom:
body {
position: absolute;
top: 0;
bottom: 0;
}
I'm working on a website that fits perfectly in the browser window. Below is a basic blueprint of the website layout:
So far, the Red area is just display:block. The Green area is also display:block with margin-right:200px. The Blue areas(nested in a div) is float:right.
So I've got the width sorted. It's the height I need advice on. The Red and Dark Blue areas are a set height, but I need the Green and Light Blue areas to fit the height of the browser window view.
I'm trying to use box-sizing, but it exceeds the height of the window view because it's extending to the max height of the window. Sorry for my poor explanation. Any advice if would be excellent. Thank you!
For green div set height: calc(100%-{red-div-height}); and for the light blue div set height: calc(100%-{dark-blue-div-height}-{red-div-height});
This is kinda the legacy version of C-Link's answer.
jsFiddle and fullscreen
This has the limitation of any content falling below one page-full falling outside of its container (you can see if you scroll down in the fiddle, but not on the fullscreen).
Make sure our page stretches to its full height.
body, html { height: 100%; width: 100%; margin: 0; padding: 0;}
Set a static-height header.
header {
height: 101px;
background: red;
}
Create a box for everything under the header. You were on the right track with the box-sizing. We can add padding to it, in the same amount as our header. Then percentages inside it work nicely.
.content {
position: absolute;
box-sizing: border-box;
padding-top: 111px;
padding-bottom: 10px;
top: 0; left: 0;
height: 100%; width: 100%;
}
We float our aside (may or may not be the correct element, depending on contents) and set some styles on it.
aside {
float: right;
width: 20%;
height: 100%;
padding-bottom: 111px;
box-sizing: border-box;
}
.top {
height: 100px;
background: blue;
}
.bottom {
margin-top: 10px;
height: 100%;
background: skyblue;
}
This is our main, large, content area, which we float to the left. The width could be specified exactly if we wanted exact padding at the cost of additional HTML.
[role="main"] {
width: 78%;
background: limegreen;
height: 100%;
float: left;
box-sizing: border-box;
}
You can also set overflow-y: auto on our main or aside elements, to have them scroll when they run out of space. There should also be mobile styles for this page that remove the floating, absolute positioning, absolute styling, and widths should be nearly 100%.
you can always set the green box height to the window height minus the red box height.
accordingly the light box height to the window height minus the (red box height + the dark blue box height)
Edit 1: I haven't mentioned that has to be done with javascript.
Edit 2: Consider any paddings and margins too.
Could you not just give the divs a max or min height depending on their purpose?
I use a main container or wrapper div that the others would be contained in, that div is then my effective page or screen area.
<div id="wrapper">
<div id="content">
<div id="sidebar">
</div>
</div>
</div>
#wrapper{
min-height: Whatever value you want here;
max-height: Whatever value you want here;
}
It might be a good idea to set up your page using main container divs, hot only for the content but for the header and footer as well.
As an example, I have a main wrapper that is the whole page, within that is the header div, the content div, the nav div and the footer div. These are the main ones. Everything else can then be contained within them.
So, you can set the layout out using percentages so you have a fluid design that'll react to each browser size. The other elements will then 'fit' inside the main divs and be constrained to them. You may need to look into positioning etc but this is certainly the direction you should head towards.
<div id="wrapper">
<div id="header">Header Here including any divs to be contained within this space</div>
<div id="content">All content etc here</div>
<div id="nav">This is your sidebar</div>
<div id="footer">Footer, as per header</div>
</div>
Then use the css to re deisgn the above layout focusing only on those main divs. Use % instead of px to maintain fluidity.
#wrapper{
width: 100%;
height: 100%
}
#header{
width: 100%;
height: 20%
}
#content{
width: 70%;
height: 60%;
float:left;
}
#nav{
width: 30%;
height: 60%;
float:left;
}
#footer{
width: 100%;
height: 20%
}
A pretty common trick is to give the green (and light blue) box absolute positioning, a padding AND a negative margin. Because 100% width is relative to the containing box (could be a parent div, or just the window itself) this is not suitable. When the header was a relative height, say 10%, it would've been easy. The padding makes sure the content will not disappear behind the header, the negative margin puts the box back in place. Don't forget the z-index (otherwise the content (green part) will overlap the header).
The css looks like this:
.header { position: absolute; width: 100%; height: 100px; background: red; z-index: 1; }
.content { position: absolute; width: 100%; height: 100%; padding: 100px 0 0; margin-top: -100px; background: green; z-index: 0; }
The fiddle looks like this: http://jsfiddle.net/2L7VU/
So I've seen this post: Can I scale a div's height proportionally to its width using CSS? and it sort of answers my Question. I can get divs to sclae porpotionally as I need. However, what I also need is to set a minimum height for those divs.
In this fiddle http://jsfiddle.net/FBZuB/1/ I have set up what I am trying to accomplish. The BLUE div is a general wrapper that then defines the height of the RED div based on the width of the BLUE div. However when I try to change the min-height on the RED div, the divs that I want to scale AND have a min-height, unexpected results occur.
I would think once I scale DOWN to the min-height point, the div would stop scaling and only change in width. However, it seems like setting the min-height just sets some sort of base point for the whole calculation and everything scales continually. I hope this makes sense.
The RED divs should scale up and down, but at a certain point, when the RED div hits its minimum height, it should stop scaling in height and only in width. I have accomplished this before with pure javascript, but since I read the post above, I am trying to get a CSS only solution.
Here is the code. You can ignore the content for now... I am focuses mainly on the red blocks. Proportionally scale width/height, until it hits the min-height and then it should stop scaling the height and only the width.
HTML
<div style="background: blue; width: 70%;">
<div id="left">
<div class="content"></div>
</div>
<div id="right">
</div>
</div>
CSS
div {
margin: 5%;
float: left;
background: red;
position: relative;
}
#left {
width: 50%;
padding-bottom: 60%;
min-height: 100px;
}
#right {
width: 30%;
padding-bottom: 60%;
min-height: 100px;
}
.content {
position: absolute;
width: 90%;
margin: 5%;
background: green;
top: 0;
left: 0;
height: 90%;
}
Unfortunately plain CSS is unable to calculate any expressions in all browsers except IE, and as such you will have to use at least some JavaScript to dynamically calculate the width.
I would probably do something like this in your html file.
Since you didn't specify how you are resizing your div, I'll assume that it's just when the window resizes.
<body onresize="
var left = document.getElementById('left');
if (left.clientHeight < left.style.min-height) {
left.style.cheight = left.style.min-height;
}
">
</body>
I'm trying to get a simple solution for this layout.
This is the simplified html.
<div class='wrapper'>
<div class='header'></div>
<div class='middle'> TEXT </div>
<div class='footer'></div>
</div>
Header and footer have a fixed height in pixels.
middle can have a variable height, depending on the content.
I want wrapper to have a minimum height of 100%. So if the text inside middle is small, the middle div should expand to fill the browser page. And if it's too long, the whole page should be scrollable.
Is this possible easily? Maybe changing something in the layout?
here's your solution: http://jsfiddle.net/S4akv/1/
You do NOT want to set a hard height for the .middle. If your content is only a few lines then you will end up with scrollbars where none are needed.
With a header and footer, you also don't want height: 100% on your .middle class because it will push your footer down, forcing a scrollbar no matter what. You also don't want a clear-cut height:100% because most browsers will interpret this as 100% of the browser height, so when you resize your browser to be larger, either the height won't change or the footer won't move.
The best solution here is to have your wrapper and any associating backgrounds attached to that. Depending on the content within your .middle div this answer could change, but given the simple parameters this is the most elegant way to do it.
the secret is to make sure that all containing elements have a height set. reason being, any block element with height: 100% will only be 100% of the area containing it. in this case you need to set height for middle, wrapper and body, html
body,html { height: 100%; margin:0; padding:0; }
.wrapper { min-height: 100%; width: 100%; background-color: red; position:relative; padding-bottom: 200px; }
.header { height: 200px; width: 100%; background-color: blue; }
.middle { }
.footer { height: 200px; width: 100%; background-color: green; position:absolute; bottom: 0; }
If you have nested content within .middle that also needs to be 100% height there is a better way, using a combination of height, absolute positioning and negative margins. There are a million ways to skin a cat. Well, a handful at least :)
edited to add padding to .wrapper to make room for footer. The bottom padding of wrapper must be the same height as the footer
