I am trying to use absolute positioning to position a div containing a blue square. For some reason, I am unable to get it where i want it to go.
JSFIDDLE: http://jsfiddle.net/qkF3Z/
My Code:
#share-area-arrow {
position: absolute;
height: 10px;
width: 10px;
background-color: blue;
}
How it should look:
What could I be doing wrong?
There are 2 pieces. Position absolute will use the coordinate system of the closest relatively positioned parent. So you need to add position relative to the parent:
#share-something {
margin-right: auto;
margin-left: auto;
margin-bottom: 40px;
height: auto;
width: 540px;
overflow: auto;
position:relative;
}
and then position the arrow:
#share-area-arrow {
position: absolute;
top:10px;
left:70px;
height: 10px;
width: 10px;
background-color: blue;
}

A really great explanation between the different position types can be found here: http://alistapart.com/article/css-positioning-101. The gist is when you want the element to maintain it's space within the dom, but appear in another location, use position relative. If you want to completely move the element use position absolute.
This creates the expected result:

Updated CSS - I used relative positioning instead.
#share-area-arrow {
position: relative;
height: 10px;
width: 10px;
background-color: blue;
top: 20px;
left: 70px;
}
Alternatively, if you feel you need absolute positioning, use:
#share-area-arrow {
position:absolute;
top: 30px;
left: 192px;
}

I have 3 divs on top of each other having following css.
.d1 {
position: relative;
background-color: yellow;
height: 50px;
width: 100px;
overflow: hidden;
}
.d2 {
position: absolute;
background-color: green;
height: 25px;
width: 50px;
}
.d3 {
position: absolute;
left: 83px;
}
and the divs that have classes are as follows:
<div class="d1">
<div class="d2">
<div class="d3">text</div>
</div>
</div>
and as a result I see content of d3 cut off because of overflow:hidden in d1.
How can I avoid cut off content of d3 without modifying d1?
Getting around the overflow..
An element can overflow from a relative or absolute positioned parent by setting its position to fixed. An element that has position: fixed will have the default left,right,top, and bottom styles set as auto. This will position .d3 to the top-left of .d2, and then the left: 83px style will push it to the left from there.
Making up the additional space..
However, to get that additional movement to the right as the original markup, you will need to add margin-left: 8px, which will make-up the additional ~8px needed to replicate the original. Further adjustments to the position of .d3 will need to be done by setting the margin style (see below).
Your updated code should look like this..
.d1 {
position: relative;
background-color: yellow;
height: 50px;
width: 100px;
overflow: hidden;
}
.d2 {
position: absolute;
background-color: green;
height: 25px;
width: 50px;
}
.d3 {
position: fixed;
margin-left: 8px;
left: 83px;
}
Some considerations and caveats..
As a previous commenter mentioned, best practice would be to fix your html markup because this solution could cause issues if you ever need to move the position of .d3. For example, setting left,right,top, or bottom will cause the default setting of this style, auto, from being unset, and the element will be positioned relative to the viewport rather than the parent relative or absolute element.
What's the proper way to position an HTML element according to a center handle?
In this example:
XXXXXXXXX
|
|
123px
Assume the element should be position at absolute position left: 123px; but the text should be centered at that point, not start at it. The element text is dynamic, so I have no way of setting a static negative margin-left on it.
Is there a pure CSS way to achieve this? The JS way of measuring offsetWidth and then setting left after calculating width / 2 won't neccesarily work in my case due to various limitations.
One posibility is to set a transform translateX -50%
p {
position: relative;
display: inline-block;
left: 100px;
transform: translateX(-50%);
}
<p>ONE</p>
<br>
<p>TWO, LONGER</p>
<br>
<p>THREE, the longest</p>
It's fairly easy to achieve that and there are several ways to do it. Since you didn't post any HTML construct for your example, I'll just make up some.
The trick is to have an inline-block parent element which has the desired offset (123px) and inside that element you'll have another inline-block element with a left margin of -50%. Position both relative and you'll have the effect you are looking for.
#container {
position: relative;
}
#line {
width: 100px;
height: 100px;
left: 123px;
position: absolute;
border-left: 1px solid red;
}
#text {
left: 123px;
top: 50px;
display: inline-block;
position: relative;
}
#text p {
position: relative;
background: green;
margin-left: -50%;
display: inline-block;
color: #fff;
text-align: center;
padding: 10px;
box-sizing: border-box;
}
<div id="container">
<div id="line">
<-- 123px
</div>
<div id="text">
<p>
This is some dynamic text<br>the div has no absolute set width.
</p>
</div></div>
There are other ways as mentioned, probably depends on your general layout/HTML structure. I would definitely take a look at the flex-box properties, this might also be suitable here.
If you want to play around with it, here's a fiddle.
Some of various ways to do this with css:
If your element is a block:
.element{
width: 200px; /* Full width */
left: 50%;
margin-left: -100px; /* Half width */
position: absolute;
display: block;
}
or, if you're using css3:
.element{
width: 200px; /* Full width */
left: calc(50% - 100px);
position: absolute;
display: block;
}
You can also have a non-absolute approach, but the parent element position should be relative:
.element-parent{
position: relative;
}
.element-parent .element{
margin: 0 auto;
}
If you use text-oriented element (inline-block), this works with IE 7+:
.element-parent{
text-align: center;
}
.element-parent .element{
display: inline-block;
}
I'm trying to apply absolute position on an error label elemennt, which is inside an input field that is also positioned absolutely. The problem is that auto-width on the error element won't apply correctly, and will break after the first word. Why is that happening? If I use position right instead of left, it seems to work fine. Here's a jsfiddle link: http://jsfiddle.net/u793ata5/
Here's the HTML code:
<div id="outside">
<div id="inside">
<label class="error">Show this error on the side</label>
</div>
</div>
And CSS:
#outside {
position: relative;
width: 250px;
height: 250px;
}
#inside {
position: absolute;
top: 30%;
height: 30px;
left: 40%;
width: 80%;
}
.error {
width: auto;
position: absolute;
left: 90%;
top: 10%;
background-color: red;
color: white;
}
Why so many absolutely positioned elements? Maybe I'm not understanding what you want the layout to look like--and maybe you could clarify--but this modified fiddle looks more reasonable to me.
http://jsfiddle.net/u793ata5/3/
.error {
background-color: red;
display: block;
margin-left: 50%;
color: white;
}
I try not to use position: absolute unless I...uh absolutely have to.
You're putting it's position at 90% from the left. This means it only has 10% of the parent width to place text before wrapping. Try using
float: right;
instead of
left: 90%;

As you can see from the picture, my parent container is not expanding to fit my child container. The page container (#contain) actually stops at the bottom left hand corner of the kitchen photograph. The child container (#zone2) is clearly overflowing outside its parent container (#contain). I would like to be able to have (#contain) expand automatically to fit (#zone2). The CSS is:
#contain {
position: relative;
width: 100%;
margin: 0 px;
background: #E3DCCC;
z-index: 0;
}
#zone1 {
width: 100%;
height: 850px;
background: url(http://waly1039.com/sites/default/files/k4.jpg) no-repeat center top;
position: absolute;
z-index: -1;
}
#head {
position: absolute;
top: 20px;
width: 100%;
height: 330px;
}
#head img {
max-width: auto;
height: auto;
}
#zone2 {
position: relative;
overflow: hidden;
padding: 3px;
top: 360px;
float: right;
right: 15px;
width: 53%;
height: auto;
border: 4px solid #715E40;
background-color: white;
}
#zone2 img {
max-width:100%;
height: auto;
float:left;
margin: 5px;
}
#zone3 {
position: relative;
top: 710px;
left: 15px;
float: left;
height: 340px;
width: 38%;
border: 4px solid #715E40;
background-color: white;
}
This is a float issue. Try adding the traditional CSS clear fix to #zone2's container:
.container:after{
visibility: hidden;
display: block;
font-size: 0;
content: " ";
clear: both;
height: 0;
}
Be sure to put this in the :after pseudo selector, otherwise it won't work for you. Floated elements exist outside of normal document flow, which is why the container isn't expanding to contain them. The clear fix forces the floats to be cleared, which will cause the container to expand around the bottom of this element.
I tested adding more images to #zone2 and #contain expands vertically. Somehow you've got an element(s) in #zone2 with padding or margins that aren't being added to the parent's total height.
If you want a quick fix in order to move on then add margin-bottom: 30px; to #zone2.
I've duplicated your problem and was able to resolve it with this: You might want to try it. It's looks a bit odd so make a class for it if you like. I'm more concern with where it is placed.
Just beneath lines of your code, add my third line. Just that and you are done. Note, it more about positioning.
<div id="zone3"></div>
<div id="zoneclear"></div>
<br style="clear:both; float:none; display:block; height:1px;" />
Just add the third line.
and just modify one of your styles:
#zoneclear {
clear: both;
float:none;
display:block;
height: 30px;
position: relative;
}
[EDIT]
The codes have a serious bug in firefox which is not present in Google Chrome (that I tested in earlier due to your relative positioning. So I've modified the #zoneclear style to fix that. You might have to test if the other browsers like this hack.
I hope it helps you
I would like to make the blue element sit halfway up the green circle and behind it. How can I do that? Also, why is there a random marginal-space between the green circle and the blue element?
#profile-circle {
margin-right: auto; margin-left: auto;
height: 164px; width: 164px;
border-radius: 84px 84px 84px 84px;
}
#main-container {
margin-right: auto; margin-left: auto;
height: 400px; width: 450px;
}
http://jsfiddle.net/LqJ79/
position: relative will help you here. It allows you to use z-index to put the circle over the box, and also you can use top which will move the box relative to its current position. The problem with position: absolute is that it takes the element out of the flow, which is not what you need here I think.
#profile-circle {
position: relative;
z-index: 100;
}
#main-container {
position: relative;
z-index: 50;
top: -100px;
}
See the demo
Use attributes "position: absolute;" in the second box, I updated js fiddle CSS with the following:
#main-container {
margin-right: auto;
margin-left: auto;
height: 400px;
width: 450px;
background-color: blue;
position: absolute;
top: 80px;
}
The easiest way to move the blue element up is to set a negative top margin:
margin-top: -82px;
However, with your current markup, the blue element will sit on top.
You can either put the green element below the blue one in your HTML, then use CSS to slide it up, or you can:
use position: relative; on both elements
set a z-index on the blue and green elements to determine which appears on top (give the green element a higher number so it appears on top)
set top: -82px; on the blue element to slide it up under the green one
The space between them is due to your margins:
margin-top: 15px;
margin-bottom: 5px;
you can make the position: fixed;
top:10px;
left: 10px;
z-index: 1;
and what not in the css to move them around. like this:
http://jsfiddle.net/LqJ79/
The 'magical' space between the two is due to the margin in the div user-info. I changed the CSS to the following:
#user-info {
height: auto;
width: 380px;
margin-right: auto;
margin-left: auto;
}
This will removed the space.
