height:100% margin white space/block problem - css

I followed this css-tricks how-to, to implement a sticky footer. I was successful but noticed that the (min)-height:100% has an negative effect on when I try to apply a margin-left of right to my primaryContent div.
At a certain height it causes a block of whitespace to show up. The only work-around I've found so far is to use padding instead of margin.
The height that this happens can be seen in my screenshot below. And I also notice if I remove the "background:inherit" line from #primaryContent div that the background of the container div stops at the same height that the margin white space problem occurs.
Any type of help is appreciated, links to the source code are:
default.css
index.html
reset.css
Screenshot:

very strage how they let that slip here is a fix :D
look for this in the default.css
html, body, #container {
height: 100%;
}
replace it with
html, body {
height: 100%;
}
Im not completely sure what the explanation for why this happens it could just be an css bug but there is always a work around.
bada-bing your done!

Click the "Reference Link" at the bottom of your example URL....it points to the original source: http://www.cssstickyfooter.com/.
If you click the "How to Use the Sticky Footer Code", you'll find that because the way their/his solution is written - padding for height attributes is proper - not margins.
I read through the documentation a week or so ago - thought I saw that caveat. <find>+padding will take you right to the notation.

Margin bug...I don't understand what is wrong

Some strange is happening in applying the styling of css code in some browsers...
Please take a look in the example...
http://jsfiddle.net/3FepW/3/
In Chrome the green div is bigger, than in Firefox, I really don't know what is the problem, I think in Firefox it displays as it should but in Chrome and IE9 it displays different.
I tried a lot of changes, can't resolve this for days.., I can use height: 100% or overflow hidden but I can't use one of them because: overflow hidden hide everything inside, but I have some draggable/sortable elements and height: 100% because I have a resizable function that will enlarge the yellow div...
The problem comes from something known as margin collapsing. Chrome and IE are rendering it correctly. Not sure what Firefox is doing.
There are many questions in here regarding the same problem. I've answered one of them here - Adding CSS border changes positioning in HTML5 webpage
Basically top and bottom margins between siblings, and children and parents collapse to highest of them. The float: left you put on .c1 prevents that from happening . The margin-bottom on .c3 gets stuck inside .c1 and that's why it gets bigger (that is, 'that's why .c1 gets bigger').
Try adding overflow: auto; to .c2- another way of preventing margins from collapsing - so c1's margin gets 'stuck in' .c2 instead - I'm assuming that's probably what you're looking for.
Here's a fiddle -> http://jsfiddle.net/joplomacedo/3FepW/5/ .
Remove the margin-bottom: 10px; from .c3 - this is what causes such behavior. As far as I know such issue is often referred to as 'collapsible margins', please, somebody correct me if I'm wrong.

HTML and Body Viewport issue

I have a website at filmblurb.org.
The page-container of my site extends to the bottom of the window when you scroll out to make for a 100% CSS layout style, but for some reason even when the height is 100% for both the body and tag, those two elements go about halfway down the page and then stop when the viewport is zoomed out. When I'm profiling those elements in Google Inspect Element that is. My page-container is currently min-height: 100%, but that for some reason actually does extend to the bottom of the viewport when zoomed out.
I've also taken screenshots of what I'm seeing to give you a better idea. Here they are [link]i917.photobucket.com/albums/ad16/jtarr523/… (for the body) and
(for the HTML)...Both are not extending to the bottom.
Anybody know how to fix this?
I would appreciate it.
min-height: 100% on the html element means that that element will be at least as tall as the viewport. It does not mean that it will always extend to the bottom. If you scroll down, then you may still be able to scroll below the bottom of the <html> element.
The only way to prevent this (short of JavaScript) is to ensure that all elements on the page (that is, everything that could possibly cause a scrollbar) is kept within the html element. A simple way to force this is to put overflow: hidden on your html element:
body {
overflow: hidden;
}
If the problem is being caused by a float, then that will solve it. If the problem is caused by an absolute-positioned element or a negative bottom margin on the last element, then that will replace your problem with a more serious one: the page will be cut off at the bottom of the html element. You will then have to find the problem element some other way.
(The same applies to the body element; it will need its own overflow: hidden; to ensure that nothing can extend beyond it.)
Not sure exactly if it would work with browser zoom, but in my experience (and according to this question) you need to set the html tag height to 100% if you are setting container elements to min-height: 100%.
html { height: 100%; }
body { min-height: 100%; }
Replace body with a reference to your main container and it should still work. As far as I can tell there are no adverse reactions to setting html to 100%; it doesn't cut the page off or mess up any other styles.
Like I said, I'm not 100% sure this is related to your problem, but it's probably worth a shot.

CSS white space at bottom of page despite having both min-height and height tag

I am unable to get the white space at the bottom of this page to disappear. I have both min-height and height tags in body. Any suggestions? Thanks!
http://womancareolympia.webs.com/
I find it quite remarkable that out of 6 answers, none of them have mentioned the real source of the problem.
Collapsing margins on the last p inside #fw-footer is where that extra space is originating from.
A sensible fix would be to add overflow: hidden to #fw-footer (or simply add margin: 0 on the last p).
You could also just move the script inside that last p outside of the p, and then remove the p entirely; there's no need to wrap a script in a p. The first p (#fw-foottext) has margin: 0 applied, so the problem won't happen with that one.
As an aside, you've broken the fix I gave you in this question:
CSS3 gradient background with unwanted white space at bottom
You need html { height: 100% } and body { min-height: 100% }.
At the moment, you have html { height: auto } being applied, which does not work:
(This happens with a window taller than the content on the page)
The problem is how 100% height is being calculated. Two ways to deal with this.
Add 20px to the body padding-bottom
body {
padding-bottom: 20px;
}
or add a transparent border to body
body {
border: 1px solid transparent;
}
Both worked for me in firebug
In defense of this answer
Below are some comments regarding the correctness of my answer to this question. These kinds of discussions are exactly why stackoverflow is so great. Many different people have different opinions on how best to solve the problem. I've learned some incredible coding style that I would not have thought of myself. And I've been told that readers have learned something from my style from time to time. Social coding has really encouraged me to be a better programmer.
Social coding can, at times, be disturbing. I hate it when I spend 30 minutes flushing out an answer with a jsfiddle and detailed explanation only to submit and find 10 other answers all saying the same thing in less detail. And the author accepts someone else's answer. How frustrating! I think that this has happend to my fellow contributors–in particular thirtydot.
Thirtydot's answer is completely legit. The p around the script is the culprit in this problem. Remove it and the space goes away. It also is a good answer to this question.
But why? Shouldn't the p tag's height, padding and margin be calculated into the height of the body?
And it is! If you remove the padding-bottom style that I've suggested and then set the body's background to black, you will see that the body's height includes this extra p space accurately (you see the strip at the bottom turn to black). But the gradient fails to include it when finding where to start. This is the real problem.
The two solutions that I've offered are ways to tell the browser to calculate the gradient properly. In fact, the padding-bottom could just be 1px. The value isn't important, but the setting is. It makes the browser take a look at where the body ends. Setting the border will have the same effect.
In my opinion, a padding setting of 20px looks the best for this page and that is why I answered it this way. It is addressing the problem of where the gradient starts.
Now, if I were building this page. I would have avoided wrapping the script in a p tag. But I must assume that author of the page either can't change it or has a good reason for putting it in there. I don't know what that script does. Will it write something that needs a p tag? Again, I would avoid this practice and it is fine to question its presence, but also I accept that there are cases where it must be there.
My hope in writing this "defense" is that the people who marked down this answer might consider that decision. My answer is thought out, purposeful, and relevant. The author thought so. However, in this social environment, I respect that you disagree and have a right to degrade my answer. I just hope that your choice is motivated by disagreement with my answer and not that author chose mine over yours.
I had white space at the bottom of all my websites; this is how I solved the matter:
the first and best thing you can do when you are debugging css issues like this is to add:
*{ border: 1px solid red; }
this css line puts a red box around all your css elements.
I had white space at the bottom of my page due to a faulty chrome extension which was adding the div dp_swf_engine to the bottom of my page:
<div id="dp_swf_engine" style="position: absolute; width: 1px; height: 1px;"></div>
without the red box, I would have never noticed a 1px div. I then got rid of the faulty extension, and put display:none on #dp_swf_engine as a secondary measure. (who knows when it could come back to add random white space at the bottom of my page for all my pages and apps?!)
Try setting the height of the html element to 100% as well.
html {
min-height: 100%;
overflow-y: scroll;
}
body {
min-height: 100%;
}
Reference from this answer..
This will remove the margin and padding from your page elements, since there is a paragraph with a script inside that is causing an added margin. this way you should reset it and then you can style the other elements of your page, or you could give that paragraph an id and set margin to zero only for it.
<style>
* {
margin: 0;
padding: 0;
}
</style>
Try to put this as the first style.
The problem is the background image on the html element. You appear to have set it to "null" which is not valid. Try removing that CSS rule entirely, or at least setting background-image:none
EDIT: the CSS file says it is "generated" so I don't know exactly what you will be able to edit. The problem is this line:
html {
background-color: null !important;
background-position: null !important;
background-repeat: repeat !important;
background-image: url('http://images.freewebs.com/Images/null.gif') !important;
}
I'm guessing you've put null as a value and it has set the background to a GIF called 'null'.
There is a second paragraph in your footer that contains a script. It is this that is causing the issue.
It is happening Due to:
<p><script>var _nwls=[];if(window.jQuery&&window.jQuery.find){_nwls=jQuery.find(".fw_link_newWindow");}else{if(document.getElementsByClassName){_nwls=document.getElementsByClassName("fw_link_newWindow");}else{if(document.querySelectorAll){_nwls=document.querySelectorAll(".fw_link_newWindow");}else{document.write('<scr'+'ipt src="http://static.websimages.com/static/global/js/sizzle/sizzle.min.js"><\/scr'+'ipt>');if(window.Sizzle){_nwls=Sizzle(".fw_link_newWindow");}}}}var numlinks=_nwls.length;for(var i=0;i<numlinks;i++){_nwls[i].target="_blank";}</script></p>
Remove <p></p> around the script.
(class/ID):after {
content:none;
}
Always works for me
class or ID can be for a div or even body causing the white space.
I had the same problem when parsing html to string. Removing the last <p></p> (and replacing it with an alternative if desirable, like < /br>) solved it for me.
I faced this issue because my web page was zoomed out to 90% and as I was viewing my page in responsive mode through the browser developer tools, I did not notice it right away.

How to fix this common problem of position:fixed elements not expanding to its parent width?

Have a look at this fiddle: http://jsfiddle.net/h4VS7/
How do I make the yellow element align (horz) with the grey background no matter how the window is resized? I refuse to believe it can't be done with css. Yes, js hacks and Scroll Follow plugin works but lags.
Please, anyone?
Edit:
Found a solution. If the container margins are expressed as percentages the content part can be expressed as the remainder percentage. See here: http://jsfiddle.net/h4VS7/1/
Though not sure why it doesn't align perfectly. It should I think. Could be jsfiddle margin/padding related.
It's not particularly difficult if you don't mind adding an extra element to wrap .top:
http://jsfiddle.net/Ud3ZQ/
And also, a properly aligning (well, almost) version of your solution:
http://jsfiddle.net/h4VS7/3/
The problem was that jsFiddle loads http://fiddle.jshell.net/css/result-light.css:
body {background: white; padding: 10px; }
Anything is more specific than * (including body), so the padding was being applied, regardless of * {padding:0; margin:0}

Floats messing up in Safari browsers

I have a site I made really fast that uses floats to display different sections of content. The floated content and the content that has an additional margin both appear fine in FF/IE, but on safari one of the divs is completely hidden. I've tried switching to padding and position:relative, but nothing has worked for me. If I take out the code to display it to the right it shows up again but under the floated content.
The main section of css that seems to be causing the problem is:
#settings{
float:left;
}
#right_content{
margin-top:20px;
margin-left:440px;
width:400px;
}
This gives me the same result whether I specify a size to the #settings div or not. Any ideas would be appreciated.
The site is available at: http://frickinsweet.com/tools/Theme.mvc.aspx to see the source code.
I believe the error lies in the mark up that the color picker is generating. I saved the page and removed that code for the color picker and it renders fine in IE/FF/SF.
Have you tried floating the #right_content div to the right?
#right_content{
float: right;
margin-top: 20px;
width: 400px;
}
Sorry I should have mentioned that as well. I tried floating that content right and additionally tried floating it left and setting the position with the thinking that both divs would start out at left:0 where setting the margin of the right would move it over.
Thanks
A few things you should fix beforehand:
Your <style> tag is in <body>, when it belongs in <head>
You have a typo "realtive" in one of your inline styles:
<a href="http://feeds.feedburner.com/ryanlanciaux" style="position:realtive; top:-6px;">
Try to get your page to validate; this should make debugging the actual problems far easier.
