getting something outside a div - html

Well I'm not sure how to ask this with words so I will post an image:
So in the image, there is a main div, lets call it "red".
Inside "red" there is another div called: "green"
Inside "green" there is an ul, with some li elements, they are supposed to have an underline, but that underline must get out of the div, so the problem I have, is getting that line outside of "green", when in the code, it is inside.
I'm guessing there might be some kind of overflow setting or some technique to achieve this, maybe its much easier than I think, but I just can't figure it out.
The sum it up, I need to get something from within a div, and get it to show outside of it as well.
I tried to google it as much as I could but I couldn't find anything that worked for me, maybe because I'm not even sure how to ask.

That depends on situation. If it is fixed size elements and they are always same size no matter what you could do it:
Position red div as relative, then green div as absolute and ul again as absolute. That will allow you move elements. Relatively to red div.
If it is stretching elements depending on size of window, it is harder and margin-left, margin-top and float:left would do the trick, but you should be very careful with it as it is hard to make cross-browser.

You cannot solve this with overflow. What you need to do is to let the ul inside green be set to position: absolute and the red box to position: relative.
I made a jsfiddle for it (my first).

see the demo as per your requirement :-
DEMO
HTML
<div class="red">
<div class="green">
<ul>
<li>loreum</li>
<li>loreum</li>
<li>loreum</li>
<li>loreum</li>
</ul>
</div>
</div>
CSS
.red {
width:300px;
height:300px;
background:red;
}
.green {
float: right;
height: 200px;
margin: 30px 30px 0;
width: 200px;
background:green;
}
.green ul {
left: 8px;
margin: 0;
padding: 0;
position: absolute;
width: 200px;
}
.green ul li {
list-style-type:none;
display:block;
border-bottom:1px solid white;
text-align:right;
}

Use "overflow : hidden" (css) for green div

I want to remove this spacing between border and screen, is it possible to do that?
There are 2 solutions:
You can remove your parent block paddings (set it to 0)
You can wrap your .content with an additional block and set its margins to negative values (adjust numbers to fit your layout):
.wrapper { margin: 0 -5px; }
Divs are block-level elements and will take the full width that is available. So, the issue isn't actually the .content div. It's likely that the body has a margin still set on it. It will probably take care of it if you add:
body { margin: 0; }
This is just a guess that it's on the body, but really it's whatever parent or ancestor has margin or padding.
Same problem here
*,html {
margin:0;
padding:0;
}
Hope this helps, "*" will set the whole page to 0

when overlapping an img-tag it renders background / border behind and text in front of img

For a simple landing page I wanted to let some text box overlap an header image. To make it simple, I just have a structure like:
<header>
<img src="path/to/img.png" />
<h1>Awesome headline</h1>
</header>
All elements are set to display:block and the h1 is dragged inside the image with a negative margin. I also gave the headline some padding and background:white.
Now the problem: The headline text is shown on top of the image but the background colour is behind it! You can see an example here: https://jsfiddle.net/cv12evLn/
My guess is, that a browser renders all sibling blocks in layers, starting with all backgrounds and borders, then rendering images (img-tags) and finally text on top of everything else.
Is that right? And why the actual… I mean, that seems crazy unexpected to me.
To solve the issue, I've put the headline in a wrapper and set this to position:absolute. See here for a live example: https://jsfiddle.net/f5sd1u6o/
Use position:relative rather than negative margin. Then the z-index works automatically.
#container {
width: 500px;
height: 300px;
margin: auto;
}
#container img {
display: block;
width: 100%;
}
#container h1 {
display: block;
width: 50%;
height: 1em;
margin: auto;
padding: .5em 1em 1em;
font-size: 3rem;
background: yellow;
text-align: center;
border: 1px solid red;
position: relative;
top: -4.6rem;
}
<div id="container">
<img src="//placekitten.com/500/300">
<h1>
headline
</h1>
</div>
To get the Z-index to work, you need to apply position:relative anyway but you can still use negative margin if that is a design requirement.
JSfiddle demo (with negative margin)
Basically, backgrounds are rendered first before anything else (as I understand it) so they always come at the bottom of the stacking order. You just need to create a new stacking context and changing the position property does that.
As it happens so does changing the opacity of the element so a quick fix is to set opacity:.9999;

Why content won't take a different background color?

I have the whole page set to gray as the background color, but would like only the content area to be set to a different color. According to my CSS, this should be happening but it isn't. Why not?
html,
body {
background-color: #FAFAFA;
}
#page-wrapper {
margin: 0 auto;
padding: 0;
width: 1024px;
}
#content {
background-color: blue;
}
OK, well, I thought there might be an obvious answer, because this is a severly slimmed-down version of my code. Yes it has content and there are things in the page-wrapper.
The jsfiddle link is here: http://jsfiddle.net/2pzo80Lu/
Also, if anyone has critiques of the code otherwise, it would be much appreciated.
You need to add overflow:auto to your rules for #content because the children are floated. Floating them essentailly removes them from the normal flow and collapses the parent since it behaves as if there's no content. Adding the overflow rule restores the behavior you seek.
#content {
background-color: blue;
overflow:auto;
}
jsFiddle example
your elements inside #content div is floated right and left so the div has no height ( 0px ) , you can solve this in css by adding the following code
#content {
background-color: blue;
overflow:auto;
}
or in html by adding the following code before the close of the element of #content
<div style="clear:both;"></div>
this will clear any floating and you code should work very will. good luck

extending background horizontally outside div

I have some css:
.note {
background: red;
}
.note > div {
max-width: 780px;
margin: 0px auto;
position: relative;
padding-left: 20px;
border: 1px solid black;
}
.note > div:before {
content: '⚠';
position: absolute;
left: 0px;
}
And a corresponding html like:
<div class='note'><div>Foobar</div></div>
This creates a red line across the screen, but the content will be only in the center area. It works well so far. But I want the whole content to be in a 800px width area, so I add a container:
#container {
max-width: 790px;
margin: 0 auto;
background: green;
border-radius: 10px;
padding: 5px;
}
And some html:
<div id='container'>
<p>Lorem ipsum</p>
<div class="note"><div>foo</div></div>
<p>Foobar</p>
</div>
Of course, note won't work here (the red line doesn't extend beyond the green container). I've been trying to come up with something, but I couldn't. I can't just close the container, place my note, and open another because border-radius and (and also box shadow, but I left it out from the example) would break then. Using a negative margin on .note also doesn't work, because it adds horizontal scrollbars. I could make .note position: absolute;, but then my note would overlap whatever comes after it.
Any ideas how could I solve it?
Update: Here's a JSFiddle. The second version is what I actually want, except that it creates a vertical scrollbar. The third is like Robert's solution, and the only problem is that it takes the div out of flow, and I'd like to avoid hacks like adding a margin-top to the following element because I don't know the length of the note in advance.
.note {
background: red;
position: absolute;
left:0;
right:0;
}
Here's a jsfiddle:http://jsfiddle.net/ySVZb/
Note that I changed some widths so it's easier to see in the jsfiddle screen, but the size is irrelevant. Also note that because I've taken the note div outside the normal flow, you will need to add an appropriate margin to anything that follows or it will fall behind the note div. Some generic like .note + * {margin-top: 2em} will work in some cases, but it will override any margin top already on that element, in those cases you'll need a more specific fix like .note + p {margin-top: 3em;} jsfiddle showing that here: http://jsfiddle.net/ySVZb/1/

Setting element to width 100% to allow background to flow, but retaining children in 960px in center?

Edit 2: It seems clear that no one seems to be able to understand what I'm asking, so I'll try to illustrate it;
The area in the center has the id #navigation. This has the following CSS properties,
width: 960px;
margin: auto;
background: #e4bd04;
The reason it has a width of 960px, is because I would like the links in my navigational bar to remain within a 960px limit. I'd also like them centered, so I apply margin: auto. However, this means that my background only flows for 960px. I'd like the background to flow for the entire window width (100% of page), so that users with larger screens don't end a huge chunk of white space at the top.
In order to prevent this, I nest #navigation into another id, #navouter, to which I apply width: 100%; and background: #e4bd04;, so that the background now appears to extend for the entire width of the window.
Is there any way to do this without using two elements as I've done?
I've undestood, you don't want to have 2 div to center another div with fixed width, isn't it ?
I don't think that you'll love it, but this is a solution :
.nav {
width:960px;
position:absolute;
left:50%;
margin-left:-480px; // width / 2
}​
<body>
<div class="nav">Test content</div>
</body>
Result for 300px div : http://jsfiddle.net/7GTCc/1/
Or another, really ugly (lol) :
.nav {width:960px;}​
<center>
<div class="nav">Test content</div>
</center>
Edit regarding your illustration
"Is there any way to do this without using two elements as I've done?"
No :-)
But if you only want the background to be 100%, don't specify a background (color or url) to your #navigation.
Last try to answer, test this :
#navigation {
min-width:960px;
text-align:center;
}
Demo here : http://jsfiddle.net/7GTCc/3/
you could use min-width property , dont know what exactly you are looking for
<div style="min-width:960px; width:100%"></div?
Yes, this is easy to do without additional markup. Use the ::before pseudo-element for the expanding part of the navigation.
Demo: http://jsfiddle.net/ThinkingStiff/eAf7w/
HTML:
<div id="nav">navigation</div>​
CSS:
#nav {
background: #6D7B8D;
height: 40px;
margin: 0 auto;
width: 400px;
}
#nav::before {
background-color: lightblue;
content: '\00a0';
display: block;
height: 40px;
left: 0;
position: absolute;
width: 100%;
z-index: -1;
}
