I'm trying to implement a div, that looks like a tall and narrow page, like a notebook paper.
I have my content in <div id='centerframe'/> and I thought that a good solution was to use an absolute positioned div for the "paper".
So I wrote the css rules as follows:
div#center_background
{
z-index:-1;
position:absolute;
top:0;
left:130px;
width:900px;
height:100%;
background:rgba(255,255,255,0.9);
}
However, when I add a background image to body, it disappears under the background. I tried setting a positive z-index, than it renders on top of everything in the page, like centerframe, topbar etc. See the picture:
A solution could be setting z-index for all the elements, which I really don't want to do, since I want to use position:absolute;'s as little as possible.
So how can I define this kind of background div without changing other elements' positions and z-indices?
I made a fiddle, but it runs as expected. The strange thing in my real code is, when I load the page, the center_background div appears on top of background of body for a glance, then it disappears.
I don't change anything with JavaScript.
I came across this in my own code a few days back, and setting containing elements to position: relative solved the issue.
When i see your picture, i think that absolute positioning is unnecessary.
You could use fixed for the header, and let main content slides under it :
http://jsfiddle.net/jgYXr/
body {
background:url(http://lorempixel.com/100/100/abstract/10);
}
nav {
position:fixed;
top:0;
left:0;
right:0;
line-height:3em;
background:tomato;
box-shadow:0 0 1em 0.5em;
text-align:right;
}
a {
display:inline-block;
margin:0 0.5em;
padding:0 0.25em;
}
main {
width:80%;
background:rgba(255, 255, 255, 0.75);
box-shadow:0 0 1em 0.3em;
margin:2em auto;
min-height:800px;
}
<nav>
Nav link
Nav link
Nav link
</nav>
<main>
</main>
Search for position: fixed and how to size an element in absolute or fixed via coordinates. See as well to set height of 1 element that has only 1 line of text.
put the z-index value in high range
div#center_background
{
z-index:100;
position:absolute;
top:0;
left:130px;
width:900px;
height:100%;
}

In the wordpress-theme Avada (A demo site) I can see that they're using some background-effect for overlapping both backgrounds and text-elements at the same time. The first heading is overlapped by the "Who we are" section. How do they do this?
Look for the div with the class tfs-slider flexslider main-flex
<div class="tfs-slider flexslider main-flex" ...>
You will notice that it has the attribute position: fixed. This means that it does not scroll with the content. In addition, they have changed the z-index properties of various elements so that it stays beneath the menu at the top and the content that flows up over it.
Basically this resumes down to this CSS property:
background-attachment: fixed;
Here I have a basic example for you: http://jsfiddle.net/1j3w8ru6/
Here is a really simple working example
What we are doing here is setting the position of the first heading to "fixed", pushing the content just below the screen with "margin-top", and setting the content's z-index to a higher value than that of the first heading.
Here is the CSS:
html,
body {
width:100%;
height:100%;
}
#heading {
width:100%;
height:100%;
position:fixed;
top:0;
left:0;
background:#000000;
z-index:2;
}
#content {
width:100%;
position:relative;
z-index:3;
background:#FFFFFF;
margin-top:100%;
}
I am trying to place an image in my body, using a div id with a background image. I don't understand why the image isn't showing up when i preview in google chrome?
I am using almost the same code on my index page and it's working fine there.
HTML:
<body>
<div id="body">
<div id="rainforestimage"></div>
</div>
</body>
CSS:
#body {
width:1024px;
height:auto;
background-image:url(../images/background2.png);
margin:0 auto;
background-repeat:no-repeat;
overflow:hidden;
}
#rainforestimage {
background-image:url(../images/exhibits/rainforest.png);
width:1024px;
margin:0 auto;
margin-top:74px;
height:364px;
position:absolute;
z-index:1;
box-shadow: 0px 8px 12px -4px rgba(0,0,0,0.46);
}
Your div#body needs to have a height set, try setting a height and you will see your background image.
Also your HTML page and the folder images should be siblings (same level) in the same directory.
EDIT:
If you still don't see background2.png, it's because rainforest.png is covering it(on top of it) because of the other styles you have set:
position:absolute;
z-index:1;
Div with position absolute ideally takes 0 height. you need to set height either 100%, or top:0 & bottom:0 .
Try using following CSS code.
#rainforestimage {
background-image:url(../images/exhibits/rainforest.png);
width:1024px;
margin:0 auto;
margin-top:74px;
height:364px;
position:absolute;
z-index:1;
box-shadow: 0px 8px 12px -4px rgba(0,0,0,0.46);
height:100%;
top:0;
bottom:0;
}
You were not able to see it because the height wasn't set.
Added in CSS
#body {
width:1024px;
height:200px;
}
https://jsfiddle.net/neerajsonar/72wr5n7u/
The image overlaps, you can set the margin according to your image.
You are keeping same width for #body and #rainforestimage,and for #body you are having height:auto,if you have only one div #rainforestimage under #body then ideally body width will be same as of #rainforestimage div,so no point you can see the background image.
so if you need increese the height of the div #body and reduce the width of your #rainforestimage,so that you can see the background image.
this will work for sure.
If you are facing any layering issues,Use z-index,make sure that the element is having position property.
Try adding min-height to div #body. actually #body won't have height because the element #rainforestimage you placed inside is positioned absolute.
#body {
min-height:364px;
}
I have been looking for an answer to this question all over the interwebs, but I just can't find the answer.. I have a transparent header filled with a background image that is the same as my background, and I want my main div to scroll underneath it so the text is hidden. Here is the HTML:
<body>
<div class="wrapper">
<div class="top">
<!-- This is my header -->
</div>
<div class="main">
[.....]
</div>
And here is the CSS:
.top {
background-image:url("http://img138.imageshack.us/img138/9215/headerqrk.png") no-repeat top center fixed;
margin-top:0px;
height:100px;
width:1000px;
margin-left:auto;
margin-right:auto;
vertical-align:central;
padding-left:0px;
padding-right:opx;
}
.main {
position:absolute;
top:100px;
bottom:20px;
left:0;
right:0;
width:990px;
margin:0 auto;
padding-top:10px;
padding-left:5px;
padding-right:5px;
z-index:-1;
}
I have made a jsFiddle which can be found here: http://jsfiddle.net/qcaJJ/. Can you please help me out on how to get this working? Thanks in advance!
ps. Please don't mind the footer, I've used the footer from another page of mine, I don't want this one on this page :p
pps. If anyone knows a way to let the nav stay on it's place and the main2 div scroll, you're my hero! Kinda new to HTML and CSS..
In addition to using fixed position for the header, as the other answers pointed out, you're also using a background image with transparency, so when the main section scrolls underneath, you still see it. You need to add a background color like so, to make sure that the header div covers over what's scrolling underneath:
.top {
background: #fff url("http://img138.imageshack.us/img138/9215/headerqrk.png") no-repeat top center fixed;
See my JSFiddle here: http://jsfiddle.net/qcaJJ/3/
You need a fixed position for your header rather than an absolute positioning for all the rest of your page.
.header{
position:fixed;
top:0;
left:0;
width:100%;
height:100px;
background:red;
}
.content{
margin-top:100px;
font-size:180%;
}
The top must be position:fixed for that to work. This ensures that it is always stuck at the top of the screen.
You may also want to set the z-index to something like 1000 so that it always stays on top of everything else.
I made this:
HTML:
<body>
<div id="header" >
</div>
<div id="main" >
</div>
<div id="footer" >
</div>
</body>
CSS:
body
{
margin:0px;
}
#header
{
width:100%;
background-color:black;
height:60px;
}
#main
{
width:300px;
border:1px dotted black;
margin:0 auto;
}
#footer
{
width:100%;
background-color:black;
height:40px;
position:absolute;
bottom:0px;
}
http://jsfiddle.net/VpwQQ/2/
But as you can see, the main div doesn't have a height.
Then I replaced my css by that:
body
{
margin:0px;
}
#header
{
width:100%;
background-color:black;
height:60px;
}
#main
{
width:300px;
border:1px dotted black;
position:absolute;
margin:0 auto;
bottom:60px;
top:80px;
}
#footer
{
width:100%;
background-color:black;
height:40px;
position:absolute;
bottom:0px;
}
http://jsfiddle.net/VpwQQ/1/
But then, the horizontal center doesn't work.
How can I do this design (div centered and that takes all the page in height between the header and footer with a 20 px magin) ?
I'm not sure what you're trying to do, but I'll give my explaination of what's going to happen with your code:
Your #main div doesn't have a height because it doesn't have a height CSS property, nor does it have any content.
You should add either a height: 100px or just add some content and you will see it gets a height.
The reason why I ask what you want to do is because you're not very clear as to what you want your final product to look like.
You're going to have another problem with the footer. If you use position absolute it sticks to the bottom at the moment. Set the height of the #main div to something ridiculously high and you'll see that when you have to scroll down the page the footer stays where it is. See http://jsfiddle.net/VpwQQ/3/
You should use position: fixed but this will keep it on the bottom of the WINDOW and not the DOCUMENT. So then you get into the problem of having to use Javascript in order to measure the document height and setting positions appropriately. Not sure what you're trying to do, but if you're just trying to lay out a website then use standard relative positioning to push the footer down naturally below the #main div.
Edit:
See http://jsfiddle.net/VpwQQ/4/ if you're just trying to set up a normal website layout.
If you want the footer to "stick" to the bottom of the page all the time then you will need to use position: fixed but I don't think this works across all browsers. See http://jsfiddle.net/VpwQQ/6/
Lastly, to get both footer and header to "stick" see http://jsfiddle.net/VpwQQ/8/
I added a div inside #main.
Main now has a 100% width.
Inside, put a div of 300px, with no absolute position.
I forked your fiddle: http://jsfiddle.net/8U9P6/
Personnally I prefer the javascript solution and not using the absolute position. But this solution seems to work.
Add and overflow to contain the content in the inside div: http://jsfiddle.net/M2nZc/
Note that the page will not grow as it is absolute position.
You can't use automatic margins on an absolutely positioned element, as it's not in the document flow any more.
Use width: 100% on the #main div, then put another element inside it that you center using automatic margins.
Demo: http://jsfiddle.net/Guffa/VpwQQ/9/
Note: You may need to use height: 100% on the body and html elements for the bottom sizing to work on the #main element.
Once you fill your #main div with content, it will automatically gain height according to the content. You can simply fill it with a few paragraphs of lorem ispum to simulate content. You can now remove the absolute position and positioning CSS.
Centering a div using the "0 auto" shorthand only works when the parent element (which, for the #main div, is the body element) has a defined width. To do this, try giving your body element a width of 100%. Doing this is something that you might want to make a habit of in you CSS.
To have your #main div always be 20px below the #header div, simply add 20px of margin-bottom to your #header div. Do the same below the #main div to space the footer.
Summed up (without the footer at the bottom, for now) your CSS might read something like this:
body {
width: 100%
margin: 0px;
}
#header {
width: 100%;
height: 60px;
margin-bottom: 20px; /*here we space the header 20px from the next element*/
background-color: black;
}
#main {
width: 300px;
margin: 0 auto 20px auto; /*we append the margin to include 20px of spacing at the bottom*/
border:1px dotted black;
}
#footer {
width:100%;
height:40px;
background-color:black;
}
Example: http://jsfiddle.net/WEx3j/
If you want the footer to be 'sticky' (always be at the very bottom of your website), I advise you to employ this method.
I hope this clarified a few things.
Is there a better way to align something in the bottom right of a cell?
I have a div which only contains a background image, 10px by 10px. I am using the following styles to put it in the bottom right corner. (The cell I have it in is 40px high.)
Doing it this way causes me to lose the 30px above the div. (I'm also using it as something to click, so I can click anywhere on the right instead of only the bottom corner of the cell.)
.time_note { float:right; width:20%; min-height:40px; display:block;
margin-right:-5px; }
.time_note { background:url('/images/sheet/note_marker.png') no-repeat;
background-position:bottom; }
If this could also be done NOT using margins, that would be great.
Example Image:
You should make your wrapping class position:relative; and then whatever you have inside you can position absolutely position:absolute; bottom:0; right:0;
For example
HTML:
<div class="wrapper">
<div class="arrow"></div>
</div>
CSS:
.wrapper
{
width:100px;
height:100px;
position:relative;
}
.arrow
{
width:10px;
height:10px;
position:absolute;
right:0px;
bottom:0px;
}
You could position: absolute, and bottom: 0; right:0; to place it on the bottom right of the parent element (which needs position: relative;). Of course, this has the danger of overlapping some other info in that element.
try:
background-position:bottom right;
I believe what you are looking for is this, you just need to modify it to be on the right
