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'm trying to write an input tag that covers 100% of the div's width and have written the following CSS:
input {
min-width: 100%;
padding: 10px 10px;
margin: 8px 0;
border: 1px solid #3EE514;
box-sizing: border-box;
color: #000;
}
I've tried both width and min-width at 100% but neither work yet when I set a pixel value the input field will increase in size. How do I change the CSS to cover the whole div?
Thanks
When you say width: 100% its taking the parent element's width. But, if the parent doesn't have a specified width, then it's simply taking the 100% of 0 :)
You could either set the outer div to have a width in pixels first, or do something like
html, body {
width: 100%;
}
.outerDiv, input {
width: 100%
}
While, trying to create a body border around the website, I am having troubles creating margin between the website and the border.
I want to have a margin of 20px around the border, but I can't seem to figure out how to do this, can anybody help me?
My final goal is for the border to look close to this.
Just make a wrapping div around the content with proper media queries, something like this
Demo
#wrapper {
max-width: 1100px;
margin: 20px auto;
border:1px solid #333;
padding:20px;
background:#eee;
}
#media screen and (max-width: 1260px) {
#wrapper {
margin: 20px;
}
}
#content {
background:#ccc;
}
Have you tried css margin property?
body
{
margin: 20px;
}
You should create two divs that surround everything in your body, like that :
<html>
<head>
[...]
</head>
<body>
<div id="global">
<div id="global-inner">
[Your original code ...]
</div>
</div>
</body>
</html>
Then you just have to do some css
#global {
border: 1px solid #CCCCCC;
margin: 40px auto;
width: 90%;
}
#global-inner {
margin: 7% 7%;
}
See the JSFiddle : https://jsfiddle.net/9usf2hmh/
Hope I helped you :)
What you should do is just use padding on your body, or main container.
Keep in mind that in that particular page design, the padding is on left/right and top, the bottom padding is part of the footer element and that's how he achieve the top-border on the bottom elements
Here a working example
I have a header with 60px height when document width is greater than 760px. So, the body is show just below the header and no problem, but when width become smaller, the height it's two lines (120px) so the body is partially hidden at the top.
How can I solve this?
Here is the code I use:
.main_header {
width:100%;
height:auto !important;
background-color:#F2F2F2;
border-bottom:1px solid #CCC;
position:fixed;
top:0px;
z-index:100;
}
.main_body {
margin:70px auto;
}
Note: The page is responsive.
You can set the margin of .main-body first to be 120px, which will apply to all window sizes. Then you can override the margin at a specific width using a media query. Note: with the CSS shorthand you are using, the main-body top and bottom margins will be affected.
<style>
.main_body {
margin:120px auto;
}
#media(min-width: 761px){
.main_body {
margin:70px auto;
}
}
</style>

Fiddle
I would like to have multiple divs with margins and below them one that fills up the rest of the space provided by the fixed size parent div.
EDIT: I am sorry, I should have mentioned that the container divs size is fixed and should not change at all.
EDIT2: SOLUTION.
I had tried overflow: hidden but missunderstood it and put it on on the child element and not the parent.
Hope this is you want http://jsfiddle.net/FR5Ud/33/
Use min-height so that your basic look of the page remains the same and it increases based on the content
#container {
float: left;
background-color: green;
width: 300px;
min-height: 300px; height
border-color: violet;
border-style: solid;
border-width: 10px;
}
#content {
background-color: blue;
min-height: 100px; height:auto
}
#toFillUp {
background-color: red;
/* that's what it should end up looking like.
However, what if the size of #content changes?
What if there are more content divs before that?
What if those have margins? */
min-height: 200px; height:auto
}
