Div container shows wrong width and overlaps second container - html

As can be seen here (please make it wider): http://jsfiddle.net/CZayc/1368/, I wanted to make my navbar width 100% of browser width, and place some links (First Second Third Fourth) in the centered, 1200px wide space.
I do not know why, but the middle container just overlaps the navbar.
Changing position: absolute; on navbar caused it to shrink to 1200px size (not desired).
What can I do about it? There is also a problem with link container, because I couldnt center First Second Third Fourth in the desired 1200px space (probably due to overlap).
Thanks!

Using absolute position on an element takes it out of the content flow: meaning that other elements in the flow act like its not there. The elements overlap because there is nothing to push the middle content down below the header.
There are 2 things you could do:
stop using position absolute. as #NendoTaka suggests, relative should be fine. If there is some reason for absolute positioning you haven't explained, then
add a margin to the middle content area.
Example CSS
.middle {
background-color: #7f7f7f;
height: 1050px;
margin: 74px auto 0; /* height of nav plus its borders*/
}

You can move .middle out of the way by adding margin-top: https://jsfiddle.net/CZayc/1371/
Be sure to set margin-top to the height of .nav. This includes borders, too.

Change your nav class to
.nav {
background-color: #34384A;
height: 70px;
width: 100%;
border-top: solid;
border-bottom: solid;
}
Note: You don't need the width: 100% but just in case.

You need to apply position:relative to both the .nav and the .middle
Your problem before was that .nav had an absolute position which caused the overlap. the relative positioning keeps that from happening because it formats each div relative to the previous div as written in your HTML.
.nav {
position: relative;
background-color: #34384A;
height: 70px;
/* position: absolute; */
left: 0;
right: 0;
border-top: solid;
border-bottom: solid;
}
.middle {
position: relative;
background-color: #7f7f7f;
height: 1050px;
margin: 0 auto;
}

You’re trying to solve the wrong problem with your question. The example below is a cleaned up version of your code.
* { margin:0; padding:0 }
nav {
background-color: #34384A;
height: 70px;
border-top: solid;
border-bottom: solid;
text-align: center;
}
<header>Test test</header>
<nav>
<a>First</a>
<a>Second</a>
<a>Third</a>
<a>Foruth</a>
</nav>
<div class="middle">
11111<br>22222<br>33333<br>44444<br>55555<br>66666
</div>
<footer>Test</footer>
Be mindful of the HTML you use. The HTML tags you choose should provide meaning to the content they wrap. Also you should avoid using position: absolute for general layout concerns such as this one.
Hope that helps.

Make div go all the way down the page

I'm working on a web design project for one of my classes. I cannot figure how to make the divs go down the whole page (the color)
http://jsfiddle.net/vmm1s4Lt/
http://codepen.io/bmxatvman14/pen/fihwD
Excerpt:
nav {
background: black;
color: white;
float:left;
width:20%;
height:800px;
display:inline-block;
/*margin-top: 40px;*/
padding-bottom: 40px;
position: relative;
z-index: 10;
}
#main {
background-color:#04cfe1;
float:right;
width:80%;
/*margin-right:10px;*/
}
Notes: I'm a pretty moderate coder, so I have tried height: 100% and that didn't do anything.
I'm trying to make the black side bar go all the way, and the blue span across the rest of the page.
Full page site: http://rubergaming.com/project/
Thanks a ton!
You can achieve this by using height 100%, but you may have forgotten that you also need to give container elements a height of 100% in order for that to work when you are giving your #main div that 100% height. I also slightly modified some of your other styles, you may need to tweak as needed. http://jsfiddle.net/ngz6e5p1/.
/*Give containing elements, as well as our main div, a height of 100%*/
html, body, #wrapper, div#main {
height: 100%;
}
/*This is overriding styles you already had - I changed the nav's height from 800px to 100%, and removed padding which will cause there to be an extra white space under the main blue nav if present */
nav {
height: 100%;
padding-top: 0px;
padding-bottom:0px;
}
What do you mean for the black bar to go all the way? And to span the blue div across the rest of the page try this:
<div id="main" style="
position: absolute;
margin-left: 20%;
bottom: 0;
top: 0;
">
//ALL THE OTHER STRUFF INSIDE THIS DIV
</div>

How do I lock a sidebar to the height of a window even when a user scrolls?

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.

align nav to bottom of header

My header holds a logo image as well as my nav element. I would like my nav to sit at the bottom of the header, but without using absolute positioning or specific top/left pixels because I would like this to be responsive.
Here is my code so far
http://jsfiddle.net/Aiedail/86ZGd/
I had tried adding like a
nav{margin-top: 50%;}
but that used the full page height rather than the containing div height.
Any suggestions or help would be appreciated.
I do think the best way for you to solve this, is to set your parent container to
position: relative;
and in your nav, use
position: absolute;
bottom: 0;
right: 0;
this way, your nav is always in the rightbottom corner of your header, but your header is still relative, so you don't lose the responsiveness.
JSFiddle Here
Basically, I took your logo and the nav and made them both display: inline-block; Removed the float styles.
Then you can use the vertical-align: bottom; for the nav element.
I forked your jsfiddle here http://jsfiddle.net/tQg8d/1/
img{
#extend .layout;
padding: 10px;
width: 30%;
height: auto;
max-width: 300px;
display: inline-block;
}
nav{
position: relative;
margin: 0;
padding: 0;
width: 69%;
height: auto;
border: 5px solid $red;
bottom: 0px;
display: inline-block;
vertical-align: bottom;
I also had to make the width of the nav a little smaller so changed it to 69% so that it shows up to the right of the logo. Might be because of the border.
Hope this is will help, if like to increase header height and and nav width may fine for you
nav { width :100% }
and
header { max-height : 200px; }
I would honestly suggest you follow the position:absolute model that Jamie detailed, but if you want a different way, you can use some negative margins.
For this, though, you need to be able to specify the height of the nav element (use ems, as they work better with responsive designs).
So you would just clear the float after the image--then you can set the top margin to -xxx (whatever the height of the element is).
Here is an example:
http://cdpn.io/bfoyj
Not as pretty as using the absolute positioning, but also works.

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/

How do I place this button correctly?

I'm trying to place a button. I have its position set to absolute, so I can't figure out how to place it properly.
Its the button that says "Is this your product?"
See an example here: (removed)
I want it to be placed right on top of the widget in the right sidebar with 5px spacing all around. How do I do that?
I originally took the button from here: http://cssdeck.com/t/uHhhprW6
Appreciate the help.
if your Button will be always in same place so you can do it with:
​.but {
position: absolute;
width: 80px;
height: 25px;
background-color: #DEDEDE;
right: 0;
margin: 5px;
}​
And just edit your right or top whatever you want. little example
The quickest way I could get it to work was remove the top, left, float, and margin-left declarations from your .email rule, and change its position to relative.
.email {
position: relative; /* not absolute */
width: 220px;
height: 30px;
font: .75em "lucida grande", arial, sans-serif;
margin: 0 0 5px 0;
}
I would imagine there are much cleaner/simpler ways to make this particular button - there seems to be a lot of absolute positioning going on with the containing element and its children. But the changes I have suggested seem to work as a quick fix.
When an element has position: absolute, you have to position it using left, right, top and bottom. The values you use on this properties should be relative to the closest positioned ancestor (a "positioned" element being one with a position value other than blank or static).
Consider, for example, the following HTML:
<div id="container">
<div id="position_me"></div>
</div>
And the following CSS:
#container {
width: 500px;
height: 500px;
position: relative;
border: 1px solid green;
}
#position_me {
width: 20px;
height: 20px;
position: absolute;
left: 100px;
top: 100px;
border: 1px solid red;
}
The red box will be 100 px from the top border of the container, and 100px from the left border of the container.
See working example.
If you use position: absolute on the button, you can specify it's location using the top, right, bottom and left properties. For example, to position an element with the id button to the top right of a page, with 5px spacing both on top and at the right, you could use this CSS code:
#button {
position: absolute;
top: 5px;
bottom: 5px;
}
If you just want the element to go to the right side of the parent element, you should use float: right. Then you can use margin-top, margin-right, margin-bottom and margin-left to make sure the element gets some margin around it.
See my example Fiddle for the difference. Note that both 'buttons' are within the same div in the HTML code, but the absolute positioned one appears to be outside of that block.
