Css float next to HR-Line - css

I want a Text with an vertical line below it, right to this constellation i want a floating div. I dont want to set fixed widths. What i tried is this:
<div>
huhu
<hr class="green" />
<div style="float: right">right</div>
</div>
what i want is the text+hr flow around the red box, is this possible?

This is possible; however, the code you've given won't work without a small modification.
You need to have the right-floating div before the content that you want to wrap around it --
http://jsfiddle.net/S9mmU/1/
To ensure that the floated div never takes up more than half the screen, you can use the max-width property - max-width:50%;
<div>
<div style="float: right; max-width:50%; border:2px solid red; padding:2em; margin:1em;">right</div>
huhu
<hr class="green" />
</div>
I've added the red border, a margin, and some padding so that you can see the effect. It should go without saying that none of these should be inline styles in practice.

Use the border-bottom instead of tag and set overflow:hidden.

How to resize the width of div left to another which has float:left;?

I still have problem to well understand how the float property works in CSS. I do apologize because I know this is css basics but I really want to understand that and get a good explanation. I've created an example to show you.
Here is my page :
I just want to resize the second div at the right. When I look at it in the Chrome Developer Tools, I see that this div begins at the top left of the window and not after the red square. I'd like it to begins just after the red square to change the width properly without calculating the size of the square and doing something like
width = square size + width i want
Do you know how this it happens and how to properly resize the width of the second div ?
EDIT: the solution consists in add the float property to the second div too. The explanation is the following : floated elements are removed from the flow, so they don't stack with the non-floated elements.
You need to set float for another div too.
We generally do like below:
html
<div class="float-left">
<p>floated left</p>
</div>
<div class="float-left"><!--- to float next to previous div--->
<p>floated left</p>
</div>
css
.float-left{
float: left;
}
As per your comment:
We do clear the float values because the container contents would never been collapsed.
You need to float the second div.
Heres an example.
<div class="parent-div">
<div class="left">
</div>
<div class="left">
<p>This is the description of the image</p>
</div>
</div>
You need to set
p { display:inline; }
or
div { display:inline; }
since paragraphs and divs are block elements.
http://www.w3.org/TR/CSS2/visuren.html#block-boxes
the reason is that floated elements are removed from the flow, so they don't stack with the non-floated elements. - therefore they don't "take up space" like before. This is why your text div starts at the top left of its container.
from MDN: https://developer.mozilla.org/en-US/docs/Web/CSS/float
The float CSS property specifies that an element should be taken from the normal flow and placed along the left or right side of its container, where text and inline elements will wrap around it. A floating element is one where the computed value of float is not none.
You have to set float for both DIVs
Here is the updated code:
HTML:
<div id="main_container">
<div class="left"></div>
<div class="right">
<p>This is the description of the image <i>Random text</i>
</p>
</div>
<!--Comment below <DIV> to see the result-->
<div class="clear"></div>
</div>
CSS
#main_container {
border:5px solid #000;
}
.left, .right {
width: 100px;
height: 100px;
background: red;
float:left;
}
.right {
background: blue;
width: calc(100% - 100px);
}
.clear {
clear:both;
margin:0;
padding:0;
}
Also, just to add one more important fact related to "float" is, make sure you add "clear:both" property after "float".
Why?? Because, a common problem with float-based layouts is that the floats' container doesn't want to stretch up to accomodate the floats. If you want to add, say, a border around all floats (ie. a border around the container) you'll have to command the browsers somehow to stretch up the container all the way.
Here is the Fiddle for the same: http://jsfiddle.net/1867ud9p/7/
Hope this will help!

Effect of overflow:auto on floated divs

Short version: Why does overflow:auto cause a div to the right of a left floated div not to wrap its text around the left floated div? (Bonus: Is this an acceptable way to accomplish a column effect?)
Long version...
I have two divs that I wish to be next to each other, and displayed as columns. The div on the left has a specific width and height. And the div on the left is shorter than the div on the right. However, I do not want the text in the right div to wrap under the left div.
Here was my first attempt...
<div>
<div style="border:1px solid grey;
width:100px;
height:100px;
float:left;">
Div on the left.
</div>
<div>
Imagine lots and lots of text here...
</div>
<div style="clear:both"/>
</div>
...I knew the text in the right div would wrap under the left div. And it did.
Then I remembered a page I had created that had a column effect. I had copied and pasted it from I know not where. All it did was assign overflow:auto to the div on the right. It looks like this...
<div>
<div style="border:1px solid grey;
width:100px;
height:100px;
float:left;">
Div on the left.
</div>
<div style="overflow:auto">
Imagine lots and lots of text here...
</div>
<div style="clear:both"/>
</div>
Voila, the right divs text no longer wrapped under the first (left) div! The second (right) div appeared as a column.
So, I read everything I could find on overflow:auto and found no mention of why I should see this behaviour. Can anyone explain it to me?
Also, is this an acceptable way to achieve a column effect?
overflow: auto (or anything but visible) causes your second div to create a new block formatting context. This means the text within that div is now in its own formatting context, rather than sharing the same one as your first, left-floating div (which is the containing block of both divs), and so it is no longer allowed to flow around the first div.
Floats also generate their own BFCs, but that doesn't exactly relate to the matter at hand. It does however also prevent reflow, achieving a column effect, as shown in the other answers.
Is this an acceptable way of creating a column effect? I don't know, but it does seem unconventional. You can just float the second div as well instead for the reason mentioned above (although even that, in favor of upcoming true layout modes like flexbox and grids, is now seen as a browser compatibility hack these days, but is the best we've got for the time being).
Remember that inline content is designed to be able to flow naturally around floated content; see CSS2.1, §9.5 Floats.
Remember also that the purpose of overflow is to control content overflow in a box with a limited size. That it causes a box to create a new BFC, influencing floats as a result, is but a side effect, the reason for which is explored here. It's a lengthy read, but it includes a bit about preventing reflow, which I'll quote here for ease of reference:
And so, this change was brought about in CSS2.1, documented here. Now if you apply an overflow value other than visible only to the second box, what a browser does is push the entire box aside to make way for the float, because the box now creates a new block formatting context that encloses its contents, instead of flowing around the float. Here's what it looks like with overflow: auto for example:
Note that there is no clearance; if the second box had clear: left or clear: both it would be pushed down, not to the side, regardless of whether it established its own BFC.
By the way, yes, this means your clearing div needs to be there if you want to always clear the first div.
To get the divs next to each other they both will need a float and fit in the surrounding div.
Example:
<div style="width:200px;">
<div style="width:100px; float:left;">
content
</div>
<div style="width:100px; float:left;">
content
</div>
</div>
If you want the outlining div to grow with the largest div place overflow:hidden; to the div.. If that div doesnt have a height with it then it will scale with the larges div.
Preview:
http://jsfiddle.net/WzVBE/
Remove float:left from the first div.
<div>
<div style="border:1px solid grey; width:100px; height:100px;">
Div on the left.
</div>
<div style="overflow:auto; ">
Imagine lots and lots of text here...
</div>
<div style="clear:both"/>
</div>​
DEMO
You can try this
<div style="width:800px; background-color:#CCC">
<div style="width:300px; height:100px; float:left; background-color:#CCC">
Div on the left.
</div>
<div style="height:100px; float:left; width:500px; background-color:#999">
Imagine lots and lots of text here...
</div>
<div style="clear:both"/>
</div>

Delete white space between divs

I'm getting some strange whitespace between two divs I have.
Each div has the css property display: inline-block and each have a set height and width.
I cannot find where the whitespace is.
Here is a Fiddle
You get whitespace there because you have whitespace inbetween the divs. Whitespace between inline elements is interpreted as a space.
You have:
<div id="left_side">
<div id="plan">
<h1>div 1</h1>
</div>
</div>
<div id="right_side">
<div id="news">
<h1>div 2</h1>
</div>
</div>
Change for:
<div id="left_side">
<div id="plan">
<h1>div 1</h1>
</div>
</div><div id="right_side">
<div id="news">
<h1>div 2</h1>
</div>
</div>
However, this is a bad way to do what you want to do.
You should float the elements if thats what you want to do.
Use:
float:left;
clear:none;
In both div
If you want to retain your coding layout, avoid floats and keep each div on it's own line entirely...
<div id="leftSide">Some content here</div><!--
--><div id="rightSide">Some more content here</div>
Only add this to your CSS
h1 {
padding:0;
margin:0;
}
Space between div is only due to h1 Margin and Padding
This does the trick:
<div id="left_side">
...
</div><div id="right_side">
...
</div>
Notice how the right-side div starts immediately after the closing tag of the left-side div. This works because any space between the elements, since they are now inline, would become a space in the layout itself. You can mirror this behavior with two span elements.
Demo.
You can also add display: flex; to the divs' parent container (in this case, body). Fiddle.
best way is settings parent element's font-size to 0 then normal font-size to child elements inside that parent (otherwise inherits zero from parent)
Floated both of the elements left, also made the 30% width into 40% to fill all the space, but this isn't necessary. Please be aware, "inline-block" isn't supported by IE7 but can be fixed with a workaround.
http://jsfiddle.net/RVAQp/3/
Move these statements onto the same line:
</div><div id="right_side">
Tried using float instead of "inline-block", no problems. Just changed the display:inline-block to:
#left_side {float: left;}
and
#right_side {float: right; margin-right: 10%}
No apparent problems. Could be wrong.
Don't know why but I resolved this problem by adding border: 1px solid red;(vertical) and float: left;(horizontal) to related DIV style statement and white-spaces removed.
Parent div set to font-size: 0px and chiilds to wanted size like 17px :)

css, html help : float left and right, cutting off background to expand past div

I have a div floating left and a div floating right, and I would like to have a background-color changed. It changes the background, but it stops right before the floating divs. When I take them off, it continues having the correct background color that I desire.
<div style='clear:both;border-bottom:3px solid #999;border-top:#333 solid thin;background:#D7E7E8;position:relative;'>
<div style='width:1091px;margin:0 auto;margin-top:70px;'>
<div style='float:left;width:200px;border:thin solid black;margin-bottom:50px;position:relative;'>
float LEFT
</div>
<div style='float:right;border:thin solid black; width:800px;border:thin solid black;margin-bottom:50px;position:relative;'>
float RIGHT
</div>
</div>
</div>
thank you!
You must clear the floats so the parent can surround them.
<div style='clear:both;border-bottom:3px solid #999;border-top:#333 solid thin;background:#D7E7E8;position:relative;'>
<div style='width:1091px;margin:0 auto;margin-top:70px;'>
<div style='float:left;width:200px;border:thin solid black;margin-bottom:50px;position:relative;'>
float LEFT
</div>
<div style='float:right;border:thin solid black; width:800px;border:thin solid black;margin-bottom:50px;position:relative;'>
float RIGHT
</div>
<!--HERE IS THE CLEARING DIV: -->
<div style="clear: left;"></div>
</div>
</div>
You can also, make the parent itself float, and then you won't need the additional markup (clearing div). If you do this, then your parent will need a width specified.
EXPLANATION:
When an element is floating, the parent is not aware of its height (unless it is a floating element itself). You need a clear below the floats so that the parent div recognises the full height of all its children.
You don't need to force-clear the floats - you need only to define the overflow for any position:relative div. Overflow:hidden and overflow:auto close the div without any further intervention, on everything from IE6 up.
Change the first line to:
<div style='clear:both;border-bottom:3px solid #999;border-top:#333 solid thin;background:#D7E7E8;position:relative; overflow:hidden;'>
and it'll accomplish the same thing as forcing the div closed.

CSS: What does clearing INSIDE a floated div do?

Quick question!
Does putting a "clear" element INSIDE a floated div do anything?
Like:
<div style="float: right">
blah blah
<div style="clear: right"></div>
</div>
Somewhere somehow I got the impression that this helps the div expand to contain the content inside of it. What does it actually do? Anything?
Thanks!
An element which contains nothing but floats will collapse in height, because the floated elements are no longer in the normal document flow. In such a case, clearing after the floats will allow the containing element to retain its height.
<div id="container">
<div id="float1" style="float:left;"></div>
<div id="float2" style="float:right;"></div>
<!-- if you use a clearing element, it should go here -->
</div>
Note that there are other ways to clear than using clearing elements, such as adding overflow:hidden; to the container styles.
In your example, since the div with clear: right is nested, it doesn't clear anything. Float applies to elements at the same level. If the divs were at the same level, the second div would appear below the div that has float: right. This page has some good explanations/examples of how float works: float tutorial
In your case, not much effect. the enclosed div (clear: right) is as good as redundant.
<div style="float: right; background: red;" >
blah blah
<div style="clear: right; background: blue;"></div>
</div>
With this, you can visually see if you enclosed div made a difference.
