To keep it short here's the example of the problem.

see the first paragraph dissappears behind the header

<p>why this goes behing previous div?</p>
<p>why this goes behing previous div?</p>

css:
#header {
position: fixed;
top: 0px;
height: 50px;
width: 100%;
background: green;
}
#div_1 {
margin: 0 auto;
}
#div_2 {
margin: 0 auto;
}
#body{ margin-top: 30px; height: 3000px; overflow: auto; }
thanks in advance
Because you set the margin of your body to 30 and the height of the header to 50px.
Because the #body (margin-top:30px) is not enough to clear the header. Increase the margin value to push the first paragraph down.
I hope this helps
Giving something position:fixed; will cause that element to be fixed to wherever you place it in the browser. Since your paragraph div doesn't have any position styles, the header will be placed on top of it.
If you give each element position: relative; they will stack on top of each other.
#header {
position: relative;
top: 0px;
height: 50px;
width: 100%;
background: green;}
#body{ height: 3000px; overflow: auto;position:relative; }

I have a blog post that is 960 pixels wide.
I want parts of this blogpost to cover 100% of the viewport (from left: 0 to right: 0). It's fairly easy to do with absolute positioning but using this approach it's impossible to clear these 100%-wide elements.
HTML:
<div class="wrapper">
<h1>A header</h1>
<p>Some content.</p>
<div class="out">
<blockquote>Some blockquote.<br/> Another line.<br/>And another.</blockquote>
</div>
<p>Clears don't work here and this content is invisible :( </p>
<p>And this sucks :( </p>
<div class="out">
<blockquote>And different blockquote.<br/> Another line.<br/></blockquote>
</div>
<p>Also this is behind blockquote as well.</p>
</div>
CSS:
body {
position: relative;
}
.wrapper {
margin: 0 auto;
padding: 15px;
background: #eee;
width: 400px;
height: 1000px;
}
.out {
position: absolute;
right: 0;
left: 0;
padding: 15px;
background: #aaa;
width: 100%:
}
blockquote {
margin: 0 auto;
width: 400px;
}
Here's a demo:
http://jsfiddle.net/2rC2S/1/
Note: all blockquotes have different height so I can't set it for them. I don't want to use JavaScript (because it's fairly easy to get elements height, set this and boom, but who renders content with JS?!).
You may do this by using before and after pseudo selectors as follows
.out:before, .out:after {
content:"";
background: black;
position: absolute;
top: 0;
bottom: 0;
width: 9999px;
}
.out:before {
right: 100%;
}
.out:after {
left: 100%;
}
http://jsfiddle.net/kM3Gf/
you may find original article here http://css-tricks.com/examples/FullBrowserWidthBars/
still I am not sure about browser compatibility!
Maybe you can avoid setting the width for the wrapper and instead set it for each of the content elements?
An absolutely positioned element won't take up space in the document and thus won't push any content down.
See this DEMO
.wrapper h1, .wrapper p {
margin: 0 auto;
padding: 15px;
background: #eee;
width: 400px;
}
I feel like this should be an easy answer but cant figure out how to achieve this effect.
Essentially i'm trying to do this: http://demo.smooththemes.com/theone/
one this site, when you start scrolling the image stays fixed and the content scrolls over top. Any ideas?
Thanks for you help.

<div id="header">

<div id="content">

CSS
#header {
position: fixed;
top: 0;
height: 20px;
width: 100%;
background-color: #ff0000;
}
#content {
position: absolute;
top: 20px;
bottom: 20px;
width: 100%;
background-color:#fff;
overflow: auto;
}
I have two divs, both are floating left. "Left" div would be left column of the page. "Right" div would be the main content.
HTML:
<div id="wrapper">
<div id="content">
<div id="left">
</div>
<div id="right">
</div>
<div id="docked_div">
</div>
</div>
</div>
CSS:
#wrapper {
margin: 0 auto;
margin-top: 35px;
width: 1005px;
}
#content {
overflow: hidden;
background-color: white;
}
#left {
float: left;
width: 250px;
background: red;
}
#right {
float: left;
background: blue;
}
This works fine. Now I have the third div named docked_div. This div should be outside the wrapper and on the right side of right div (about 20px from top of right div).
So, the black div now is on the left side, but it should be on the right side and outside the wrapper.
I have tried to set position to relative or absolute in different ways, but I cannot get
the result I want. I do not have much CSS knowledge on creating layout, so, I would appreciate any suggestions and guidance.
Here is the full example:
http://jsfiddle.net/TA7Rh/
I think this will work
#wrapper {
margin: 0 auto;
margin-top: 35px;
width: 1005px;
position: relative;
}
#docked_div {
/*background: url(../images/mazais_fons.png);*/
background-size: 100%;
width: 53px;
height: 212px;
position: absolute;
right:-60px;
}
jsFiddle Link
change the right position as per your requirement.
Try this.
#docked_div {
background-size: 100% auto;
height: 212px;
position: absolute;
right: 0;
width: 53px;
}
This will take the div to be on the right of the main div. Hope this helps.
I'm trying to stretch the content of a div the height of the page. I've Googled the problem and so far nothing works. The whole thing is starting to give me a headache. Perhaps someone more experienced could take a look at my code? The full stylesheet is >400 lines, so I'm including what is (hopefully) relevant.
"Wrapper" takes up 100% of the page height, whereas "contentShadow" stretches only to the height of the text in the div "content".
Edit: as far as I can tell, every container has its height set to 100%, which whould make "contentShadow" 100% as well. Right...?
Edit 2: I'm starting to see the problem, but don't know how to solve it. While the following code will keep the footer down, it also means that since .wrapper doesn't have height:100%, "contentShadow" will not stretch. The question then is how I keep my footer down while changing this code:
.wrapper {
min-height: 100%;
height: auto !important;
margin: 0 auto -37px;
}
To this:
.wrapper {
height: 100%;
}
Basic structure of the page:
<div id="body">
<div id="headerWrapper"></div>
<div id="wrapper">
<div id="contentShadow">
<div id="#contentWrapper">
<div id="content">
<!-- contentshadow stretches the height of this content and no further, but SHOULD stretch the height of the entire page -->
</div>
</div>
</div>
<div id="push"></div>
</div>
<div id="footer"></div>
Css rules relevant to these divs:
html, body {
height: 100%;
}
#headerWrapper {
height: 314px;
width: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -37px;
}
#contentShadow {
min-height: 100%;
width: 994px;
background-image: url(../images/contentShadow.png);
background-repeat: repeat-y;
margin-right: auto;
margin-left: auto;
}
#contentWrapper {
min-height: 100%;
width: 940px;
margin-right: auto;
margin-left: auto;
padding-right: 16px;
padding-bottom: 16px;
padding-left: 16px;
padding-top: 17px;
background-color: #EDECEC;
overflow: hidden;
}
#content {
min-height: 100%;
}
.footer, .push, {
height: 37px;
}
.footer {
background: white;
clear: both;
height: 37px;
}
You have really wrong code:
.wrapper matched <div class="wrapper"> not <div id="wrapper">.
<div id="#contentWrapper"> is not correct, you should try <div id="contentWrapper">
height: auto; is the problem. The wrapper needs to be 100% height, not auto...
the height: 100% after height: auto !important doesn't make sens, because of the !important keyword.
Maybe it's the default margins and padding, have you tried this?
body {margin: 0px; padding: 0px; }
I had this issue for the better part of my life, but I just solved it for myself, so I'm sharing, just in case somebody else can benefit.
My HTML/BODY selector is set to height:100%.
My container div within the HTML/BODY selector is set to min-height:800px.
My CONTENT div inside of the CONTAINER div didn't have a height, and I had the issue of the div not stretching to the bottom of the page. When I inspected this div, I noticed that for some reason, it was stretching way below its container div, pushing it up and creating that annoying space at the bottom of the page. Once I placed a height on that inside DIV, the issue went away for me.
I hope this helps.
The contentShadow must have overflow: auto. Try this
body, html { height: 100%; margin: 0; padding: 0; }
#container { width: 100%; height: 100%; overflow: auto; display: block; }
<body>
<div id="container">
This should fill the page!
</div>
</body>
I have a div called header that is set up with a fixed position. The problem is when I scroll the page the content of the page shows up behind the header (the header is transparent).
I know a lot about css, but cannot seem to figure this one out. I have tried setting overflow to hidden, but I knew it wouldn't work (and it didn't).
This is very hard to explain, so I did the best I could.
html:
<div id="header">
<div id="topmenu">Home | Find Feeds | Subscriptions</div>
</div>
<div id="container">
<div id="content">
testing
</div>
</div>
css:
#header {
margin:0 auto;
position: fixed;
width:100%;
z-index:1000;
}
#topmenu {
background-color:#0000FF;
height:24px;
filter: alpha(opacity=50);
opacity: 0.5;
}
#leftlinks {
padding: 4px;
padding-left: 10px;
float: left;
}
#rightlinks {
padding: 4px;
padding-right: 10px;
float: right;
}
#containerfixedtop {
width: 100%;
height: 20px;
}
#contentfixedtop {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height:20px;
}
#container {
position: relative;
top: 68px;
width: 100%;
height: 2000px;
overflow: auto;
}
#content {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height: 2000px;
}
Here's a screenshot of the problem:
Just coming to this late, but in case anyone else runs across this in the future, here's your fix.
Your CSS Code:
.wrapper {
width:100%;
position:fixed;
z-index:10;
background:inherit;
}
.bottom-wrapper {
width:100%;
padding-top:92px;
z-index:5;
overflow:auto;
}
Your HTML:
<div class="wrapper">
...your header here...
</div>
<div class="bottom-wrapper">
...your main content here...
</div>
This will provide you with a header that cleanly matches your site, and floats at the top. The main content will scroll free of the header, and disappear when it passes the header.
Your .bottom-wrapper padding-top should be the height of your header wrapper's content.
Cheers!
You are probably looking for z-index. It allows you to specify the vertical order of elements on the page, so an element with z-index: 10 is floating above (visually) an element with z-index: 5.
Give the content z-index: 5 and see if it works.
I was having a similar issue, and found a solution for my case. It should apply whether you are using a full screen background image, or a solid color (including white).
HTML
<div id="full-size-background"></div>
<div id="header">
<p>Some text that should be fixed to the top</p>
</div>
<div id="body-text">
<p>Some text that should be scrollable</p>
</div>
CSS
#full-size-background {
z-index:-1;
background-image:url(image.jpg);
background-position:fixed;
position:fixed;
top:0px;
left:0px;
width:100%;
height:100%;
}
#header {
position:fixed;
background-image:url(image.jpg);
height:150px;
width:100%;
}
#body-text {
margin-top:150px;
}
This gives me the look of a full page image with a transparent fixed header and when the body content scrolls, it hides behind the header. The images appear seamless.
You could do the same thing with a solid color background, though, arguably, it would have been easier.
2 notes: the header has a set height, I have only tested in FF and Chrome.
Just came up with a new solution to this type of problem that I'm quite happy with.
Use clip-path on the content that needs to hide behind the transparent element. Then update the clip-path dynamically with js on window scroll.
HTML
<div id="sticky">Sticky content</div>
<div id="content">
<!-- any html inside here will hide behind #sticky -->
</div>
JS
window.addEventListener("scroll",function(){
const windowScrollTop = window.scrollTop;
const elementToHide = document.getElementById("content");
elementToHide.style.clipPath = `inset(${windowScrollTop}px 0 0 0)`;
});
Dynamic sticky content
In my case I had an element that I switched to position: sticky after scrolling past it. The #sticky content needs to be relative to the dom elements that came before it until we have scrolled far enough. Here's how I accounted for that:
HTML
<div id="otherStuff">Here's some other stuff</div>
<div id="sticky">Sticky content</div>
<div id="content">
<!-- any html inside here will hide behind #sticky -->
</div>
JS
window.addEventListener("scroll",function(){
const windowScrollTop = window.scrollTop;
const stickyElement = document.getElementById("sticky");
const elementToHide = document.getElementById("content");
const stickyElementTop = stickyElement.getBoundingClientRect().top
if(windowScrollTop >= stickyElementTop){
stickyElement.style.position = "sticky";
elementToHide.style.clipPath = `inset(${windowScrollTop - stickyElementTop}px 0 0 0)`;
}
else {
stickyElement.style.position = "relative";
elementToHide.style.clipPath = "none";
}
});
I fixed this problem using the background property with a color, you can use var even if you'd like to
.header{
width:100%;
position:fixed;
z-index:10;
background:blue;
/* background: var(--my-var-value); You can do this if needed*/
}
Does #header have a set height?
#header {position: fixed; height: 100px; }
#container {position: absolute; top: 100px; bottom: 0; overflow: auto; }
Pretty sure this wouldn't work in IE though...
Fix the position of the content div below the header + overflow-y the content div.
I have fixed background image
The header background is transparent
I don't want my content to override my transparent header
I came up with a solution scrolling the div instead the body:
<div>
<div class="header"></div>
<div class="content"></div>
</div>
.header { position: fixed; ... }
.content { position: fixed; height: calc(100% - HEADER_HEIGHT); overflow: scroll; }
I too faced similar issue, but solved it using a simple dirty hack
1) have a white image in images folder
2) then add this css in header style
z-index:999; // to make header above the scrolling contents
background-image : url("../images/white.png"); // to hide the scrolling content
3) It is done!!
The header's z-index is set to 1000, so the z-index of the container would have to be 1001 if you want it to stack on top of the header. https://codepen.io/richiegarcia/pen/OJypzrL
#header {
margin:0 auto;
position: fixed;
width:100%;
z-index:1000;
}
#topmenu {
background-color:#0000FF;
height:24px;
filter: alpha(opacity=50);
opacity: 0.5;
}
#leftlinks {
padding: 4px;
padding-left: 10px;
float: left;
}
#rightlinks {
padding: 4px;
padding-right: 10px;
float: right;
}
#containerfixedtop {
width: 100%;
height: 20px;
}
#contentfixedtop {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height:20px;
}
#container {
position: relative;
top: 68px;
width: 100%;
height: 2000px;
overflow: auto;
z-index:1001;
}
#content {
margin: 0 auto;
background-color: #DAA520;
width: 960px;
height: 2000px;
}
I was having the same problem. I just used added z-index:10 to the .header in CSS.
I solved this problem by adding another fixed div positioned right under my header with margin-top of the size of my header.
HTML:
<div id="header">
<div id="topmenu">Home | Find Feeds | Subscriptions</div>
</div>
<div id="fixed-container">
Content...
</div>
CSS:
#fixed-container{
margin-top: header_height;
height: calc(100% - header_height);
width: 100%;
position: fixed;
overflow: auto;
}
I was facing the same problem, so the answer that tize gave helped me alot, I created a div right under my header and used some css(z-index, overflow and background), so the main element is scrollable and hid behind the transparent header:
HTML:
<header>
<h1>Hello World</h1>
</header>
<div class="inv-header"></div>
<main>Content Here...</main>
CSS:
header{
position:fixed;
background:rgba(255,255,255,80%);
top:0;
width:100%;
z-index:10;
}
.inv-header{
position:fixed;
top:0;
height:12.8%;
width:100%;
background:inherit;
}
main{
margin-top:5.9%;
padding-top:1%;
overflow:auto;
}
