I want to have my header fits the size of my screen. Because the background-size is set on "cover" it actually widens automatically, no matter the size of the screen, but the height doesn't fit along. (Sorry for my bad english by the way.) I HAVE to put a height content in the "header td" section, but how do I fix this all? I hope it's clear enough...
CSS:
#header-wrap {
background:url(haderimage.jpg)no-repeat center;
background-size:cover;
box-shadow:inset 0 0px 0px rgba(0,0,0,0.3);
}
.wsite-custom-background #header-wrap {
background: none;
}
#header {
border-collapse: collapse;
border-spacing: 0;
width:100%;
height:100%;
}
#header td {
vertical-align: middle;
text-align: left;
height: 500px;
}
You do know HTML5 has a header tag built in automatically right?
Anyway, sounds like a margin or padding issue, probably just adding a couple of pixels to the width. Try doing a reset at the top of the css:
*{
margin: 0;
padding: 0;
}
This can make loading slow sometimes (I've personally never noticed any difference) so if it doesn't help, get rid of it. Otherwise, you could try just hiding the excess width. On your body tag, you could try hiding the overflow. This should stop the page scrolling horizontally but can cause you more width problems later.
body{
overflow-x: hidden;
}

Out of curiosity, considering the example below, why does having the margin on the #container div cause a vertical scrollbar to appear in the browser? The container is much smaller in height than the body height which is set to 100%.
I have set the padding and margins to 0 for all elements except the #container. Note that I have deliberately omitted absolute positioning on the #container div. In this case how is the browser calculating the height of the body and how is the margin affecting it?
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
* { padding:0; margin:0;}
html, body { height:100%; }
#container
{
padding:10px;
margin:50px;
border:1px solid black;
width: 200px;
height: 100px;
}
</style>
</head>
<body>
<div id='container'>
</div>
</body>
</html>
Example also on JSFiddle
If you paint the backgrounds of html and body (giving each its own color), you'll quickly notice that body is being shifted down along with #container, and #container itself isn't offset from the top of body at all. This is a side effect of margin collapse, which I cover in detail here (although that answer describes a slightly different setup).
It's this behavior that's causing the scrollbar to appear, since you've declared body to have 100% the height of html. Note that the actual height of body is unaffected, as margins are never included in height calculations.
Based upon #BoltClock♦'s answer, I fixed it by zeroing the margin...
so
html,body, #st-full-pg {
height: 100%;
margin: 0;
}
works where id "st-full-pg" is assigned to a panel div (which further contained panel-heading and panel-body)
A bit late, but maybe it helps someone.
Adding float: left; to #container removes the scrollbar, as W3C says:
•Margins between a floated box and any other box do not collapse (not even between a float and its in-flow children).
html,body {
height: 100%;
margin: 0;
overflow: hidden;
}
This worked for me
adding float:left; is nice, but will interfere with central horizontal positioning using margin:auto;
if you know how big your margin is, you can account for that in your height percentage using calc:
height: calc(100% - 50px);
browser support is good, but only IE11+
https://caniuse.com/#feat=calc
/*removes default margin & padding*/
html, body{
padding: 0px !important;
margin: 0px !important;
}
/*sets body height to max; and allows scrollbar as page content grows*/
body{
min-height: 100vh;
}
I have found a solution: add padding: 1px 0; to body prevents vertical scrollbars to appear
For those who are coming here for an easier to understand answer that even includes code samples, this answer (copied from here) is for you.
No JavaScript or definite pixel values (such as 100px) are required, just, pure CSS and percentages.
If your div is just sitting there on its own, height: 50% will mean 50% the height of the body. Normally, the height of the body is zero without any visible content, so 50% of that is just, well, zero.
This is the solution (based on this) (uncomment the background lines to get a visualisation of the padding):
/* Makes <html> take up the full page without requiring content to stretch it to that height. */
html
{
height: 100%;
/* background: green; */
}
body
{
/*
100% the height of <html> minus 1 multiple of the total extra height from the padding of <html>.
This prevents an unnecessary vertical scrollbar from appearing.
*/
height: calc(100% - 1em);
/* background: blue; */
}
/* In most cases it's better to use stylesheets instead of inline-CSS. */
div
{
width: 50%;
height: 50%;
background: red;
}
<div></div>
The above was written so that there would still be the usual padding. You could set the dimensions of the red div to 100% and still see padding on each side/end. If you don't want this padding, use this (although it doesn't look nice, I recommend you stick with the first example):
/* Makes <html> take up the full page without requiring content to stretch it to that height. */
html, body
{
height: 100%;
}
/* You can uncomment it but you wouldn't be able to see it anyway. */
/*
html
{
background: green;
}
*/
body
{
margin: 0;
/* background: blue; */
}
/* In most cases it's better to use stylesheets instead of inline-CSS */
div
{
width: 50%;
height: 50%;
background: red;
}
<div></div>
I saw this problem fixed before where you put all the contents of body in a div called wrap. Wrap's style should be set to position: relative; min-height: 100%;. To position #container div 50px from the top and left put a div inside wrap with a padding set to 50px. Margins will not work with wrap and the div we just made, but they will work in #container and everything inside it.
here's my fix on jsfiddle.
you can add non-breaking space into the body tag.
<body> <othertags>...</body>
html, body {
height: 100%;
overflow: hidden;
}
If you want to remove the body scrolling add the following style:
body {
height: 100%;
overflow: hidden;
}
Inspired by #BoltClock, I tried this and it worked, even when zoom out and in.
Browser: Chrome 51
html{
height: 100%;
}
body{
height: 100%;
margin: 0px;
position: relative;
top: -20px;
}
I guess body was shifted down 20px.
It works for me:
html,
body {
height: 100%;
height: -webkit-fill-available; // Chrome
}
// Firefox
#-moz-document url-prefix() {
body {
box-sizing: border-box;
margin: 0;
padding: 1px;
}
}
Add overflow: hidden; to html and body.
html, body {
height: 100%;
overflow: hidden;
}
I found a quick solution: try set height to 99.99% instead of 100%
I've spent 2 days trying to sort this out and I can't. I'd appreciate any help.
I have a container set to fill 100% vertically, which it does just fine. In the container I have another div for my header. Underneath the header, I want another div to also fill vertically 100% (from the bottom of the header to the bottom of the screen) regardless of how little content there is. The problem is, when I set the height for this div at 100%, it overflows past the bottom of the browser window, even if there is no other content in it. Just a long blank space. The overflow is the same size as my header.
If I remove my header, it works fine. And if I tell this div to not be 100%, then it will only go as deep as the content forces it, which won't be enough in some cases. I tried using overflow: hidden, but then that hides the shadow effect I have on the div.

And the code in question is here:
#container {
height: 100%;
position: relative;
width: 960px;
margin-right: auto;
margin-left: auto;
margin-bottom: -80px;
}
#bodybox {
height: 100%;
width: 960px;
margin-right: auto;
margin-left: auto;
margin-top: 0px;
margin-bottom: -80px;
background-color: #FFF;
-webkit-box-shadow: 0px 5px 20px 0px rgba(0,0,0,0.75);
-moz-box-shadow: 0px 5px 20px 0px rgba(0,0,0,0.75);
box-shadow: 0px 5px 20px 0px rgba(0,0,0,0.75);
}
You'll notice my footer is hovering over the bottom. That's because of the overflow. I'm using this sticky footer solution in case that's important.
I'm a bit of a novice at CSS and I really want to avoid excessive Photoshop usage or tables, but I can't seem to get any tip or suggestion I've read to fix this. Please help. Thanx.
try
#bodybox{
height: calc(100% - 142px);
...
where 142px is the height of the header. Calc calculates the height according to the arithmetic in the parentheses. Note the equation will not more without the spaces before and after the operator. The same equation can be used to counter the effect of margins too.
If you set an element to have a relative height/width (with percentages), the height/width will be relative to it's direct parent (if some exceptions do not apply, I will not explain them here). But that doesn't take positioning into account. So your content div has exactly the height you asked it to be, but because it is pushed down by the header it appears to be taller.
You could use calc to calculate the height you want, or use the oldschool push back method.
You start with building the container, header and content div:
<div class="conatiner">
<div class="header"></div>
<div class="content"><h1>My Content</h1></div>
</div>
And apply some styles:
.container { width: 300px; height: 100%; } /* height can be anything */
.header { width: 100%; height: 100px; } /* header SHOULD have a fixed height */
.content { width: 100%; height: 100%; }
And to push back you add to the styles of the .content div: margin-top: -100px;, where the 100px should be the same height as the header. With the minus in front you tell the browser to pull it back instead of push it down.
Now you have two more problems to solve. The first one is that the content div covers the header div. You can fix that with applying z-index, although that requires you to add position too (as z-index only applies to positioned elements). So add those two rules to both header and content:
z-index: 1/0; /* header has z-index: 0, content has z-index: 1 */
position: relative; /* to 'activate' z-index 'behavior' */
Now we're almost there, but as you might see the content also disappears behind the header. To fix this, add a padding to the content div:
.content { padding-top: 100px; } /* again the 100px should be the same as the header height */
And now don't despair if you see the content div pushed down again. That is because the padding adds up to the height. Luckily my great friend box-sizing helps us out!
.content { box-sizing: border-box; -moz-box-sizing: border-box; }
And here we are (fiddle)!
Note: there are some other strategies, like, absolute positioning of the content div and/or header, using the calc functions, and others. Choose what suits you best.
Quick fix:
#header_bkgd {
overflow: hidden;
}
I'm guessing its to do with the fact that they both have a margin-bottom of 80px? one is taking off the other forcing it to overflow.
Do this:
CSS:
#bodybox{
margin-bottom: -80px; //Remove
// rest of the css
}
#container {
margin: 0
}
We've got a sticky footer that is working great in anything WebKit based but doesn't seem to work in Firefox (Or new versions of IE either).
There is extra space being generated below the footer of around 200px in height that is inheriting the background colour of body.
The extra space does not seem to be part of any div that we can find, including html, body, content, wrapper etc. etc. It also does not seem to be caused by any sort of padding or margins on any elements.
We've built it on Ryan Fait's CSS Sticky Footer method that uses a push div inside of the wrapper div, with a separate footer div.
You can check it out at redesign.treepuncher.com/freetrial/
Iframe at the bottom of your page and copyright is creating unnecessary space. You can stop iframe from being displayed if that does not affect your website's functionality.
Try this code:
.copy {
color: #FFFFFF;
float: right;
font-weight: 100 !important;
margin: 95px 15px 0 15px; //Fixes margin at the bottom of this div
}
iframe {
display: none; //Stops iframe from being displayed
}
The following css should make it sticky and remove unnecessary space at bottom
.footer {
background-color: #006837;
bottom: 0;
color: #FFFFFF;
font-family: "roboto",sans-serif;
font-size: 12px;
font-weight: 100;
height: 120px;
position: fixed;
width: 100%;
}
.wrapper {
height: auto !important;
margin: 0 auto;
min-height: 100%;
}
I have a div and I've tried to set the height to 100% so the content of it makes the div grow to fit.
I've tried the following and it won't work:
Adding 100%:
#latest{ height: 100%; background: #e3e3e3 url(banner_grad.jpg) repeat-x; border: none; margin-top: 10px;}
Leaving having to height setting at all, so the div would just fit the content in:
#latest{ background: #e3e3e3 url(banner_grad.jpg) repeat-x; border: none; margin-top: 10px;}
Unless I set a specific height (e.g. height: 370px;) the div will not even show it's outline in design view in Dreamweaver. Very odd.
Any ideas?
Thanks
The height property will correct here.But instead of this use following code.If you go on adding content the div will also increase in height.
#largest {
background: url("firefox-gray.jpg") repeat-x scroll 0 0 #E3E3E3;
border: medium none;
margin-top: 10px;
overflow: auto;
}
Unfortunately you can not set heights of divs as percentages, mainly as content tends to make divs grow downwards, so you would be limiting yourself.
Take a look at the min-height css property though. That, I think, will go some way to sorting your problem.
Does the content of the div have a "float: left" or a "float: right" attribute?
html, body{
height:100%
}
div{height: 50%}
I don't know the browser compatibility of this so you may need to test it.
http://jsfiddle.net/ZKZFa/
may be you have to write like this:
html, body{
height:100%
}
#latest{
height: 100%;
background: #e3e3e3 url(banner_grad.jpg) repeat-x;
border: none;
margin-top: 10px;
}
* { margin: 0; padding: 0; }
body {
margin: 8px auto;
background: #20272D;
width: 900px;
}
body, td, input, textarea {
font: 11px Tahoma;
color: #DDD;
}
#content {
width: 400px;
margin: auto;
background: url(img/blixt.png) 0px 18px no-repeat;
padding-left: 25px;
}
There's a image (blixt.png) that I want to show up as background no matter how long the content inside <div id="content"> is! If its short only a bit of the image shows and as longer the text the more it shows. How can I fix so it shows the whole image no matter what? I don't want to set height.
You can set a min height, but that will require you to set a IE height fix because min-height won't work in IE.
The problem here is pretty obvious. You have an element with a background image but no height on it, so of course it's going to default to the height of the content inside it.
You can either put a height on the #content element, or move the background image to the body.
try this in the body css:
background-image: url(img/blixt.png) no-repeat;
background-color: #20272D;
