What is the difference between float:left and float:right within a parent with position:relative? In my testing, both result in a div being floating in the top-left corner of it's parent, overlaying the image (unless I manually position the div using right: 0px).
I can see a difference with position:absolute. float:left needs it to overlay the div over the image, with float:right I can omit it and still get the overlay effect.
Can anyone enlighten me what's going on here?
My problem is illustrated in this jsFiddle.
HTML:
<div class="parent">
<div class="tag">Featured</div>
<img src="http://www.placehold.it/200x200">
</div>
CSS:
.parent {
position:relative;
width: 200px;
}
.tag {
float: right;
position: absolute; /* can omit when using float:right */
/* right: 0px; */ /* uncomment to right-align child */
}
Edit:
I was mistaken with my statement about position:absolute and float. Somehow I got the impression when playing round with the jsFiddle, sorry for the confusion. Thanks for all your answers.
You cannot use float on an element that has set position: absolute;. Just use left: 0; or right: 0; to align them inside the parent which has position: relative;.
Also, position: relative will not touch the float behaviour of your children. It is just the position: absolute which disables the float functionality. which is the reason that your float: right is also on the left top side. With position: absolute you want to explicitly say where the element is located. floats do not fit into this role and will therefore have no effect.
Absolute positioning takes that element out of the normal flow. So when you try to use float it has no effect because it cannot flow within your .container to "float." You are telling it to ignore the rest of the elements for absolute positioning. With absolute positioning you have to state where you want it to reside within your parent. So #Francodi solution is correct. Just further explanation.
Float does neither affect elements that are position:absolute nor the parent child relationship. It only concerns elements living on the same DOM level. float:left will let the element float on the left and the other way round. clear: both applied on an element stops the floating there:

Imho you are better of using display:inline-block most of the times.

I have a main wrapper div with a content div and a button. The button is supposed to go underneath the content div but for some reason it's overlapping with it.
The content div has css:
#groupMembers {
position: absolute;
height: 50%;
width: 90%;
left: 5%;
overflow: scroll;
display: inline-block;
}
and the button has:
button {
display: inline-block;
width: 70%;
left: 15%;
}
I thought since they're both inline-block that they wouldn't overlap, but for some reason they are. I made a JsFiddle to show: http://jsfiddle.net/b5hp6boz/
Can anybody help me get the button to display beneath the content div?
Remove the (extensive) use of absolute positioning.... Change it to position: relative; if necessary. But on many elements even that is not necessary.
Move the button div up to under the <h4>add members</h4> in the HTML where you appear to want it.
Then adjust margins for #DIV_05 and the button.
Fiddle Update or Fiddle Update 2
(Note I merely performed a search to change absolute to relative in your CSS, then adjusted from there.)
By using absolute positioning so extensively you were forcing elements into unnatural positions. Then when it wasn't working out.. you are left wondering why. Let things fall where they naturally want to fall. Change the HTML for overall render order, don't force things with absolute positioning.
Use of absolute position is most commonly used to adjust z-index and make elements not alter positioning of other elements. (like a global float of sorts) It should not be the fall back for positioning everything in any layout.
The problem in your code is that you have given the #DIV_5 the following CSS:
position: absolute;
By giving a HTML element an absolute position it is removed from the normal rendering process by not obtaining any space in the document. That means it is not affecting the position of the following BUTTON_105 element. That's why the button is positioned right underneath the H4_4 element (which is the first element not having an absolute position).
To fix that simply remove the position: absolute; declaration for #DIV_5. (Btw: You should try not to make heavy use of absolute positioning as it can cause further issues.)
Try giving your div tag a higher z-index value.
The basic code:
<div parent>
<div wrapper>
<div child></div>
</div>
</div>
The basic scheme:
http://i.imgur.com/I70VL4f.jpg
The scheme shows how I want the child element to be positioned. By default, it "walls" to the left of the parent element, but I want it to wall to the right of the parent element. So let's say if the child element increases in size, it will stick out from the left side of the wrapper instead of the right side of the wrapper.
The child is to remain position: static.
Thank You.
You can use CSS for this. Give your parent div a class of parent and child div a class of child. Then in your css use the following code.
.parent{
position: relative;
}
.child{
position: absolute;
right: 0px;
top: 20%;
}
Note this top: 20% is subject to change.
You can use position and right properties. On parent use position: relative to set the relative container of children. Use right: 0px on child container to allow going to left side.
Here is a fiddle example:
Fiddle example
You cannot achieve the result with the desired efficiency by giving position: static to the child element.
For best results you will have to use position: relative and absolute combo as I stated above. Otherwise it will always be a hit and trial of margins that you will have to do manually.
I am trying to put an absolute div inside a relatively positioned div. But I don't want to define a height for the relative div.
The relative div has a background colour and when I don't define a height the absolute div goes 'outside' the relative div. I can't control how many lines the text will be so the height of the divs change
HTML
<div class="row top-footer">
<div class="top-footer-text text-center">
<div class="test">
<h1>title</h1>
<div class="footer-btn-wrap">
<div class="footer-btn">button</div>
<div class="footer-btn">button</div>
</div>
</div>
</div>
</div><!-- /top-footer -->
CSS
.top-footer {
position: relative;
background-color: #686a6f;
width: 100%;
padding-top: 40px; margin: 0;
}
.test {
position: absolute;
top: 0px; margin: 0;
}
EDIT
I want .top-footer (position: relative) to contain .test (position: absolute) with space/padding/margin on the top and bottom of .test. the height of the div is unknown because the content may take up more than one line depending on screen size
Adding whitespace around the child div is fairly trivial. However preventing the parent div from collapsing is more tricky and is the thing you need to tackle first. The problem you are having is that with the parent relatively positioned and the child absolutely positioned, the only element on the entire page that actually "knows" where the child is is the parent... and even then it's a fairly bad parent because it won't even make enough space for the child! The rest of the DOM will behave as if the element isn't even there - other non-positioned elements will float over or above it - even text will be obscured by your child div. Assuming you want to put other content in the parent div using absolute positioning in this way only means you're going to have to use absolute positioning all around the place... which can get a bit heavy on the brain debugging layout problems later on.
The only possible solutions I can think of offhand are:
Use javaascript to sniff out the height of the child div and apply that to the parent. A fairly simple job if you use a library like jQuery but that requires extra downloaded files and makes your site unnecessarily bulky if this is the only task you're using it for. THis also wouldn't solve the problem of the child div obscuring other elements on the page.
Rework your CSS (and it might take a lot of reworking depending on how far you've got and the complexity of the styling) to use display:inline-block on the child... this will stop the parent from collapsing but might give you additional layout issues.
Rework your CSS (ditto) to float:left the child div. You would then need to use a CSS "clear hack" in order to prevent the parent divv from collapsing, although this is a tiny piece of CSS you can cut and paste from elsewhere... an easy job.
If you're determined to use absolute positioning like this my preferred solution would be to use jQuery (option 1) because most of my work tends to use a degree of it anyway... it's a tool I would have handy and the code to perform this task would be quite trivial.
EDIT - Here's a little fiddle to get you started. https://jsfiddle.net/fo8mq1vf/
This is how the output of your code looks like: https://jsfiddle.net/s3zLa54t/2/. The parent div (.top-footer) does contain the .test div. What browser are you using to view the output?
As for the padding, I guess you don't see any effect of changing padding-top. Try removing the top: 0px property in the .test div.
If this is not what you were looking for, do clarify the question here.
The answer to your question is simply remove
position:absolute from your absolute div (.test)
position:relative from your relative div (.top-footer)
height:300px from your relative div (.top-footer)
This is the tested version of https://jsfiddle.net/s3zLa54t/3/ with multiple number of divs under your main div. You can check that it is not going beyond the grey background.
.top-footer {
position: absolute;
background-color: #686a6f;
width: 100%;
padding:0px;
margin: 0;
}
.test h1{
padding-left:20px;
position: relative;
top: 5px; margin: 0;
float:left;
color:#FFF;
}
.footer-btn,.footer-btn-wrap
{
padding-left:200px;
color:#FFF;
}
.footer-btn a{
padding:5px 10px;
float:left;
color:#ffffff;
text-transform:capitalize;
text-decoration:none;
}
I'm new to CSS and I have a question.
First, my HTML and CSS code:
<!-- HTML CODE -->
<body>
<div id="container">Container
</div>
<div id="inner">Inner</div>
</body>
<!-- CSS CODE -->
#container {
background-color:#b6ff00;
width:500px;
height:500px;
position:relative;
}
#inner {
background-color:#ffd800;
}
With current code, the browser shows the following page:
This is expected.
But if I add this css property to #inner element position:absolute; there will be a following output:
As you can see, the #inner div, takes only that much space it needs. Why this changed with only position:absolute; property added to #inner div?
That's because when you use position: absolute; the element will take up width upto the elements defined/content it contains., cuz it just gets out of the document flow so it is block level in nature but won't take up entire horizontal space on the document, as it's just out of the flow of the document..
If you want it to be full width you need to define width: 100%; explicitly so that it will take 100% of the relative parent's width as well as the height if you declare height: 100%;
Also, make sure you always use position: absolute; with a wrapper element set to position: relative; or your element will fly out in the wild which will eventually end up taking the viewport as the last relative wrapper if you set the position of the element using top, right, bottom or left.
I've explained here in detail, that how CSS Positioning Works
Worth to note that, you make any element a position: absolute; element, it will behave as a block level element, but you need to define height and width so for example, if you turn an inline span element a position: absolute; you can define height and width without making it display: block; (Unless and until you are using display: none; initially)
position: absolute; does not behave the same as block elements.
You will need to set a width and a height for a div that is absolutely positioned.
This is fundamentally how position absolute works. Once taken out of the flow of the document it becomes an inline-block element that is absolutely positioned within the nearest element that is positioned relatively (or the top most element)
If you need it to then be a certain dimensions you can try to set widths and heights, or you can do things like
#inner {
position: absolute;
left: 0;
right: 0;
}
...which would ensure it always stuck to the left and right sides of the screen.
It's generally good practice to put things that are positioned absolutely inside of an element with "position:relative" on it, as your code stands it suggests you want your #inner element to be placed anywhere on the page, whereas if you wanted it to be of a size and position relative to #container your code should look like this:
<body>
<div id="container">
Container
<div id="inner">Inner</div>
</div>
</body>
with CSS such as:
#container {
position: relative;
}
#inner {
background-color:#ffd800; width:500px;
height:500px;
position:relative;
}
You can see your output here:-

Let me explain a little:
Postition: relative
This will align itself in accordance with the elements found before (i.e) Prior Siblings.
You can change the position by using margin-top, margin-left, ....
Position: absolute
This will always consider from the browser's start point and won't be in accordance with anything.
Drawbacks:
You cannot consider this as the parent or anything when absolutely positioned.
You can change its position by using top, bottom, right, left.
I have multiple Div's that I am using as buttons. If I set the postition to relative I can use float left to put them all on one row next to eachother. They also appear at the top of the parent div. I want the buttons to appear at the bottom of the parent div. Is it possible to give an element two position values as in
position: relative;
float: left;
and also
position: absolute;
bottom: 0;
I have a feeling this is a logic error of some kind and I am not sure how to do this logic.
just put them into wrapper
<style>div.buttons{position:absolute;bottom:0;}</style>
<div class="buttons">...</div>
if float is problem, use display:inline-block; for positioning add position:relative to the parent div, and use position:absolute to child divs.
Please note with display inline-block you need to extra hack for IE7 *display:inline (if you are still supporting it), and if you see white space btw buttons, refer
