What is the best way to write a div which has a width of 100% (the yellow-ish ones in the pic below), without breaking the flow of the document?
<div id="container">
<div class="big">
//content
</div>
<div class="small">
//content
</div>
</div>
css:
.big
{
background-color:#whatever;
}
.small
{
width:75%;
margin-left:auto;
margin-right:auto;
}
div {position:absolute;}
or
div {postion:fixed;}
will remove it from the document flow, but you may have to specify the left and top to put it where you want it once you remove it, depending on which one you use.
A div will automatically take up the whole width of it's parent (<body> in this case). If you insert
style="clear:both"
Into the div you'd like to stretch, it will ensure that it is not alongside any other elements (following the normal flow of the page) hence it will stretch the width of the body.

I noticed this strange behavior years ago back when I was first learning HTML, and still don't understand it.
Both jsfiddles are based on the following HTML:
<div class="parent">
<div class="child">
Child content
</div>
</div>
In the first jsfiddle, I'm adding a margin-top to the child element, yet the entire parent element shifts downward: http://jsfiddle.net/flyingL123/uUgVz/
In the next jsfiddle, the only thing I'm changing is adding a border to the parent element, and now the parent element no longer shifts down the page: http://jsfiddle.net/flyingL123/uUgVz/1/
Why don't both jsfiddles behave the same? Why is the parent element effected by the margin-top on the child element in the case when the parent element does not have a border?
It is because the childis not empty (height!==0)
<div class="parent">
<div class="child">
Child content
</div>
</div>
is the same as
<div class="parent">
<div></div>
<div class="child">
Child content
</div>
</div>
empty element will be used as wrapper
and adding border to the parent is like saying hey now we want to see something which is the same as just adding a letter:
<div class="parent">
m
<div class="child">
Child content
</div>
</div>
-Demo-
Note that you are applying the style on the parent element and not the child, that means the first and all next notempty childif they dont have a style set will adopt the parent style
It has to do with how block elements are rendered. By default, divs don't hide their contents, it means that anything inside a div that results being larger than its parent would stick out of it, like the margin of your child element, however you can use the overflow: hidden attribute so that the content is limited only to the size of the container, and thus, making your margin to push from the inside of your div, since it can't stick out of it:
See the updated fiddle:
CSS:
.parent{
width:300px;
background-color:#666;
color:white;
overflow: hidden;
}
.child{
margin-top:50px;
}
But in case you still want the children to stick out of the parent but to be pushed down, you can set the container's padding value instead of the child's margin value, see this other fiddle:
CSS:
.parent{
width:300px;
background-color:#666;
color:white;
padding-top: 50px;
}
.child{
/* margin-top:50px; */
}
The effect you described is caused by Margin Collapsing
Go through this Stackoverflow to learn how to remove the margin collapsing.
I've got a number of div's with float:left;, of course they show up next to eachother but except for the floating div's wich don't fit in the wrapper div anymore.
I need the divs to stay next to eachother and flow over on the x-axis. I know it could be done by setting a fixed width to the wrapper and wrapping the wrapper in another wrapper but the width isn't static and prefer not to use a script to calculate the width.
The situation is:
<div id="wrapper">
<div class="floatleft"></div>
<div class="floatleft"></div>
<div class="floatleft"></div>
</div>
//Wrapper WITHOUT fixed width
#wrapper{
overflow:hidden;
}
.floatleft{
float:left;
width:500px;
}
You can do it with inline-block and white-space:nowrap http://jsfiddle.net/imsky/EbAFw/
<ul id="wrap">
<li>A</li><li>B</li><li>C</li><li>D</li><li>E</li>
</ul>
#wrap {margin:20px;width:300px;height:100px;background:yellow;overflow-x:scroll;overflow-y:hidden;white-space:nowrap}
li {display:inline-block;width:100px;height:100%;background:#5AA4D7;color:#fff;font-family:sans-serif}
The only catch is the markup will be white-space sensitive.
Edit: this works cross-browser, with IE7 and below just needing a *display:inline;zoom:1 at the end of the li rule.
I Want to place a div over another div without using height in pixels.I have used this code
<div style="position: relative;height:78px;">
<div style="width:425px;position: absolute;top: 0;left: 0;">
Content for First div
</div>
<div style="z-index:10;position:absolute;top: 0;left: 0;">
Content for Second div
</div>
</div>
The first div content will change dynamically . So is their any way to put height auto some thing like in parent div
both child divs are taken out of the flow, so the parent will have no natural height (which normally is "stretched" by it's children).
since you have pre-loaded data on the first child div, make the second match to it.
HTML:
<div id="parent">
<div id="firstChild">
Content for First div
</div>
<div id="secondChild">
Content for Second div
</div>
</div>
CSS:
#parent{
position:relative;
}
#firstChild{
width:425px;
}
#secondChild{
width:425px;
position:absolute;
top:0;
bottom:0;
}
NOTE: watch out for collisions in your styles, i used ID here. replace accordingly
height: 100% should make it the height of the parent div which is 78px;
This is what I want my page to look like:

I'm not quite there yet. Here's where I'm at:

I'm quite new to using <div>s (as opposed to <table>s) to create the layout of my pages. How do I get the job done?
You can fix the menu by just adding 2 CSS style rules:
.menu { overflow: hidden; }
.menu ul { margin: 0; }
The overflow will leave a taller menu because of the browser default <ul> margin, just clean this up with the second style, which will knock the margin out.
try including clear:both in the body div.
<div id="body" style="clear: both">
<p>This is my body</p>
</div>
good luck! ;-)
Simply add the below code:
<div style="clear:both; margin-left:20px;">
after the line:
<div id="body">
That is:
<div id="body">
<div style="clear:both;">
More info about the clear property.
Also, have a look at good tutorial:
Div based layout with CSS
the problem i'm seeing now is that your blue 'item' boxes don't look right. i think the reason for that is that the div containing the 'item' boxes should be contained inside the main 'body' box. it is in fact the very first thing inside the 'body' div.
to make this easier on yourself, you should create a div inside the 'body' div, with width: 100% and background: blue (or whatever color that is). then, inside that div you can create your list of items.
the obvious way to put the "items" inside the "item bar" would be to float:left all the items inside their own divs. you would then need to set a static height for the "item bar" itself (like height: 2em), because a div containing only floating elements has no height.
<div style="float:left; width:50%;">
div 1
<div style="position:absolute; width:105%">nested element</div>
</div>
<div style="float:left; width:50%;">
div 2
</div
If an element exceeds the width of its floated parent element, the next element is pushed down unless I apply overflow:hidden on both floated elements, which defeats the purpose because I DO NOT want to hide the overflowing content. Is there any fix for it?
You have to make sure the content inside is not wider than the divs to stop the elements being pushed down in this scenario.
You could perhaps put margin-right: -5% on the positioned div to make it's width narrower in the document flow, but it should still display at 105% wide once rendered.
Set it to 100%, not 105% - otherwise, it is simply doing what you told it to do.
