In an HTML page, if I align some <div>s with "right: 0px", they all look very nice, as I expect. However, if I make the browser window smaller and the horizontal scroll bar appears, when I scroll the page to the right, I see an unexpected white space (instead of the background colors of my <div>s). It seems that my <div>s are aligned relative to the visible area of the page. See the sample code below:
<html>
<head>
<style>
<!--
#parent {
position: absolute;
left: 0px;
right: 0px;
top: 0px;
bottom: 0px;
background-color: yellow;
}
#child {
position: absolute;
left: 100px;
top: 300px;
width: 1000px;
height: 400px;
background-color: blue;
}
-->
</style>
</head>
<body>
<div id="parent"><div id="child">some text here</div></div>
</body>
</html>
Is there any way to make the "right: 0px" property align the controls relative to the size of the entire page, not only the visible area?
Thanks.
The Problem is the "absolute" position in the parent element, because it's scrollable per definition.
If you set the position to "fixed" and an additional attribute overflow to "scroll", it should look like expected.
#parent {position: fixed;
overflow: scroll;
left: 0px;
top: 0px;
right: 0px;
bottom: 0px;
background-color: yellow;
}
if you add
html{ border: 3px solid red }
to your stylesheet,
you'll see that you are setting the 'right' property to the edge of the page.
I think you need to rethink your strategy.
What are you trying to achieve?
Dont use absolute position unless you absolutely must. Use margins and paddings instead. And dont forget to reset margins and paddings so you dont start with whatever the browser has as default.
Is it necessary to use absolute positioning in your case? Otherwise you can remove the left and right properties and simply use width: 100%;
my answer is i want change align scroll?
example "right align" scroll.
#ex {overflow: scroll}
Right? Bottom? Are sure these are even real CSS attributes? Normally you would just set top/left and then width/height...

How can I make a div and nested divs extend down to the full height of the screen with scrolling on the body?
Link to a fiddle: https://jsfiddle.net/qsczjd01/
CSS:
#megaAll{
box-sizing: border-box;
position: absolute;
background-color: gray;
top: 0px;
bottom: 0px;
left: 0px;
right: 0px;
}
I need #megaAll (gray), #megaMain(pink), and #contentContainer to extend all the way down the page, but it seems unable to extend to the full height because of the scrolling on the body. I need the scrolling on the body and fixed sidebar on the right to remain.
Extending them down is just height:auto; which need not to be mentioned as it is default. Whatever will be the height of your body, it will auto adjust it all over the page.
"sidebar on the right to remain" means fixed, this will work if I got you right.
position: fixed;
Use
position: fixed;
instead. This will position the element fixed in the window, rather than fixed within the body element.
Figured it out! I changed my divs from using position: absolute, and then 0px all around, to using static positioning with margins at 0px.
New example div:
#megaAll{
box-sizing: border-box;
background-color: gray;
margin: 0 auto;
}

I have this site:
http://dl.dg-site.com/functionmentes/
There is a div with color #D9D9D9
Code CSS:
#full_bar{background:#D9D9D9;width:100%;height:100px;}
I want to my div to be the full width site and to be glued to footer.
How can i make this?
I use a theme in Wordpress.
Thanks in advance!
By making the position fixed, this will ensure that it will follow the user as they scroll up and down your website.
#full_bar {
background: #d9d9d9;
width: 100%;
height: 100px;
position: fixed;
bottom: 0;
left: 0;
}
If you add position:absolute; left: 0; to the css, the bar will more or less do what you're trying to do, but it's a dirty hack.
The real problem is that you're adding your 'full_bar' in the wrong place (inside a div which restricts the width). Personally I would opt for placing the full-bar in your <footer> tag.
You should placed your gray bar outside the section, between section and footer or on footer on html.
But if you want a css solution, you need to put your section parent to position relative and set your gray bar on absolute bottom with full width:
section {
position: relative;
padding-bottom: 100px; // Your bar height
}
#full_bar{
background:#D9D9D9;
width:100%;
height:100px;
position: absolute;
bottom: 0;
left: 0;
}
You are putting #full_bar inside class="container". container is the parent of div id #full_bar, that's why its not taking full width.
Do your code outside contaner class and you can see the changes.
See the attachment, i think you want this as per i understand your question.
I have the following code:
<div style="position: absolute; width: 100%; height: 100%; background-color: #00FF00">
<div style="position: relative; left: 300px; top: 45px; height: 100%; width: 100%; background-color: #FF0000;"></div>
</div>
Screenshot:
Why does the div gets pushed outside of the viewing area and hence showing the scrollbars. If you check toward the top right corner, the black area is the extension when the red div moved.
How can I edit it so the red div has the top and the left position but doesn't extend beyond the page width and height?
To actually answer the "why" of the question:
The reason you're getting scroll bars is that the relative positioned div inside of the absolute is set to 100% width and height, but ALSO is displaced (in this case, by top and left)
It is therefor assuming 100% width/height of the parent container AND displacing it, causing it to be too large.
By adding overflow:hidden, you seemingly solve this issue, but any content past that will be clipped, not actually fitting inside the dimensions you have set.
Another way to do this would be something like...
top: 10%;
left: 10%;
width:90%;
height:90%;
You could just as easily substitute top and left for padding/margin of that direction.
You can use CSS3's calc() function to set the second div's height and width to be the same as the first one's, minus the left and top offsets. This will also allow you to use position: absolute in your text, aligning it to the right:
<div style="position: absolute; width: 100%; height: 100%; background-color: #00FF00">
<div style="position: relative; left: 300px; top: 45px; height: calc(100% - 45px); width: calc(100% - 300px); background-color: #FF0000;">
<span style="position: absolute; right: 0; top: 50%;">TESTING THIS OUT</span>
</div>
</div>
Check the working JSFiddle. I also added a CSS reset to get rid of the body margins that the browser might add. If you want to use this reset in your HTML file, create a <style> tag inside your <head> tag, with the code that is showing in the CSS section in the JSFiddle. If you don't want to use the entire reset, the only actually relevant part is body { margin: 0px; }, so you can also add style="margin: 0px;" to your body tag.
I'm running into a minor issue with one of the elements on my page. I have a sidebar which I am attempting to have span the height of the page by using the following CSS:
#sidebar {
width: 180px;
padding: 10px;
position: absolute;
top: 50px;
bottom: 0;
float: left;
background: #eee;
color: #666;
}
The corresponding CSS is pretty much what you'd expect:
<div id="header">
The header which takes up 50px in height
</div>
<div id="main-container">
<div id="sidebar">
The sidebar in question
</div>
<div id="main-content">
The rest of my page
</div>
</div>
The code works as expected for the most part. When the page renders it spans 100% of the height (minus the 50px from the top). The problem is that it essentially assigns the box to the exact height of the window so as I scroll down the box scrolls away instead of staying locked to the bottom of the window. Any ideas how to resolve this?
You have to use position:fixed if you want for the sidebar to be fixed on some position:
#sidebar {
width: 180px;
padding: 10px;
position: fixed;
top: 50px;
bottom: 0;
background: #eee;
color: #666;
}
JSFiddle
Another way would be to give to the parent container position:relative, and on his child position:absolute - but then the parent must have some height so the child element takes its height.
html,body{
position:relative;
height:100%; /* some height */
}
#sidebar{
width: 180px;
padding: 10px;
position: absolute;
top: 50px;
bottom: 0;
background: #eee;
color: #666;
}
JSFiddle
Check learnlayout to read more about positioning.
use css position:fixed to make the sidebar fixed.
in order to lock the height according to screen height i would use javascript/jquery:
$(function(){
// assign to resize
$(window).resize(set_height);
});
function set_height() {
$('#sidebar_id').height($(window).height());
}
hope that helps
First of all, I don't understand how it's spanning 100% of the height when no height has been defined.
Secondly use position: fixed instead of absolute.
On a second note, I'd like to recommend what seems a more proper way of going about positioning this. At the end of the main-container div, before it's closing tag, put this
<div style="clear: both;"></div>
and make the main container also float left, or float right if that doesnt give you what you want. It's suprising how such a common layout can feel tricky to do properly. (at least for newbies like us). I might be wrong, this might not be a better way, but it's the way I'd do it. The extra div you add is so that floated divs take up space, apart from that if it doesn't work, give the sidebar a height of 100%, or if you think it will overflow, tell me I'll add to my answer.
I added the famous "Fork me on Github" ribbon to one of my projects. The tag looks like this:
<a href="https://github.com/Nurdok/htmlify">
<img style="position: absolute; top: 0; right: 0; border: 0;"
src="https://s3.amazonaws.com/github/ribbons/forkme_right_red_aa0000.png"
alt="Fork me on GitHub">
</a>
It looks great, but some of the divs on my webpage have minimum length, so when the window is small, one has to horizontally scroll the screen. When that happens, I want the "Fork me on Github" link to stick to the top-right side of the page, not the window. This is how it looks right now:
Scrolled all the way to the left:
Scrolled all the way to the right:
It seems that the ribbon is placed on the top-right side of the initial window, and stays static.
What I want is for it to be out of sight in the first case and top-right in the second case (when I scroll to the right).
Edit: Thanks for the quick answers, people. However, most of the answers made the ribbon scroll horizontally and vertically with the page. What I want is for it to be fixed on the top-right side of the page (not the browser view), and only be seen if I scroll to where its position is.
You can do a little trick and put your image into a div which has minimal-width.
<div style="position:relative;min-width:960px">
<img src="..." style="position: absolute;right:0;top:0" />
</div>
and put that div at the beginning of <body> section.
position:relative makes that all children of that elements that have position:absolute are positioned absolute according to that div, not whole page. When viewport is bigger than min-width, the div is the same width as the viewport. When the viewport is smaller, the div will have the min-width and the image stays at the corner of the div.
Two alternatives
Sticking to the Viewport: To stick it to the viewport you should position your element "fixed" instead of "absolute"
<img style="position: fixed; top: 0; right: 0; border: 0;"
Sticking to a Container: And if you want it to be sticked to a container (so youn dont see it when you browse left) use absolute but do that container position:relative so its containing block is targeted
If you dont want to see the image when scrolling left then use a explicit width for this container I am talking about
Here is a JSFiddle example.
I used a squared div instead of an image. CSS code as follows:
#container {
width: 700px;
height: 700px;
background: #55ff90;
position: relative;
}
#image {
width: 70px;
height: 60px;
background: #ffff90;
position: absolute;
top: 0px;
right: 0px;
}
In case it's supposed to stick to the right top on horizontal scroll only, you can't accomplish this with basic CSS. Your requirement is stick to the right top for horizontal scroll but not vertical scroll. The first part of the requirement can be accomplished using position: fixed; though this breaks the second part.
How about always sticking to the right top of the website using a relative float: Fiddle
<div id='container'>
<div id='sticky'>x</div>
</div>
#sticky {
width: 100px;
height: 100px;
background: red;
float: right;
}
#container {
width: 100%;
height: 200px;
background: blue;
}
You should use float:right, adjusting margin if you need, e.g.: margin-right: 5px. Cheers :)
If I understand what you want correctly, you'd like for the image to stick to the top corner of the window UNTIL the window gets to a certain size (horizontally) and then stick.
If so, here is a plausible solution:
body{
min-width:1000px; /* or whatever you need it to be */
}
#ribbon{
position:relative;
float:right;
}

You can also use a container div with min-width, your choice.
Change position: absolute; to position: fixed.
As side note, put the style on the a instead of the image and add some z-index to make sure it stays on top of everything else:
<a href="https://github.com/Nurdok/htmlify" style="position: fixed; top: 0; right: 0; border: 0; z-index: 999; display: block;">
<img src="https://s3.amazonaws.com/github/ribbons/forkme_right_red_aa0000.png"
alt="Fork me on GitHub">
