I know this title is probably about the most common on SO, but I seem to have a very specific problem that I can't find documented.
I have a div that I want to be exactly square, so I followed the CSS advice in this answer. I also want a child div to fill this space, so I've followed all the standard guidelines of having a clear:both div in a wrapper, etc, but my child div is still not filling its parent. The problem is the height: 0 of the parent div - is there a solution to this but still maintaining the exact square (preferably pure CSS, I'm aware there are JS solutions). Example of this is at this fiddle.
You can give the inner box an absolute position and set it to conform to the edges of the containing box:
.box div {
position: absolute;
top: 0; right: 0; bottom: 0; left: 0;
border: 1px solid black;
display: block;
background-color: rgba(0,0,0,0.1);
}
jsfiddle
Not sure if it's any better to what you proposed, maybe if you wanted content in the box?
If you're not too worried about support then using vh, vw, or vmin would be a good alternative. Since height would actually be set you could easily set the child element to fill the parent.
CSS:
.parent {
width: 50vmin;
height: 50vmin;
background-color: blue;
margin: 0 auto;
}
.child {
width: 100%;
height: 100%;
background-color: red;
}
HTML:
<div class='parent'>
<div class='child'></div>
</div>
Here's an example. I like vmax, but it's not as well supported as vmin, vh, and vw.
This padding trick for responsive boxes work with absolute positioning.

So use absolute positioning for inner div.
.box {
...
position: relative;
}
.box div {
...
position: absolute;
left: 0;
top: 0;
}
Adding padding-bottom: 100% to the child div does fill the space and seems to be a fix; the updated jsfiddle reflects this

Please take a look at the attached image, it makes it easier to understand.
In general the question is just how to absolute position an element left:100% while making it appear a bit less than 100%. Margin doesn't seem to work in absolute positioning.
I created a resizeble element with jQuery, and there is a right 'bullet' for the user to resize the element. I don't want to bullet to be on top of the container's border, so I set its position to absolute, and left: 98%.
Problem is - resizing the element takes the bullet to the left or right of the container's end, depending on its size (because the position of the bullet is set in percentages). Only 'solution' is to set its 'left' to 100%, but then the bullet is on top of the div. Adding a non breaking space after the bullet also didn't work since I had to set the left to 98% to contain both the bullet and the space.
What do you think? Is there a simple solution I didn't come up with?
Thanks in advance,
OmerImage
Edit: Jila here offered a simple solution of using calc:
#myContainer {
position: relative;
display: inline-block;
box-sizing: border-box;
}
#bullet-right {
position: absolute;
left: calc(100% - 16px);
margin-right: 10px;
top: 40%;
color: blue;
z-index: 5;
}
I tried 100% - 10px without the calc before and it didn't work obviously
Hope it can help others and thanks Jila
left only works on a positioned element. That is to say, any element that does not have the default static positioning. In addition to this, you should never set left: 98%; you should set right: 2% to prevent any confusion.
If you want to set a left offset on a dynamic element, you're looking for margin-left.
This can be seen in the following:
.container {
border: 1px solid black;
padding: 20px;
}
.text {
border: 1px solid black;
margin-left: 5%;
padding: 5px;
display: inline-block;
width: 85%;
}
input {
margin-left: 2.5%;
}
<div class="container">
<input type="radio">
<div class="text">Text</div>
</div>
how to absolute position an element left:100% while making it appear a bit less than 100%.
Don't use left: 98%;. Use right: --;. Since, as you state, percentages are dynamic, decide on a fixed value for the element offset. For example if you choose 10px the element on the right would be right: 10px and the element on the left would be left: 10px;.
If you really really want to use left for the one on the right use left: calc(100%-10px);, but there's no real reason for doing that when you can use right.
I want to know how to position multiple div's on each other, without position absolute in HTML.
I tried with position: absolute but due to this, I have to specify container div height explicitly, which I don't want to do.
How do you want to place them exactly ?
If they are div, they should be on top of each other with position: static by defaults. If you don't want to use position: absolute, you could use negative margins. This is not a recommended solution, but the hack definitely works.
.d1 {
background-color: red;
height: 200px;
width: 150px;
}
.d2 {
background-color: blue;
height: 150px;
width: 100px;
margin-top: -100px;
}
<div class="d1"></div>
<div class="d2"></div>
Note that you can use % margins if needed but the % margin properties will always be a percentage of the parent block WIDTH. So be careful with that.
NB : Tanks to #Oriol for correcting mistakes I made. I edited my answer thanks to his advice.
Not sure what you're trying to achieve but I can imagine only one scenario, where something like that would be usefull. Namely switching between several divs. If that's the case use display:none on all but the current div.
In anyway child div is by default "overlapping" with parent div, so I assume what you mean is that you want siblings to be "on each other"... however that sounds.
The only way to do this is (except for negative margin hacks) absolute and relative positioning.
Here's how:
#foo{
background-color:red;
height: 50px;
width: 50px;
position: relative;
}
#bar{
background-color:blue;
height: 50px;
width: 50px;
position: absolute;
}
#foobar{
background-color: green;
height: 50px;
width: 50px;
position: absolute;
}
#raboof{
background-color: yellow;
height: 50px;
width: 50px;
}
<div id="foo">
<div id="bar"></div>
<div id="foobar"></div>
<div id="raboof"></div>
</div>
Jsfiddle: https://jsfiddle.net/t81hvsa1/
Keep in mind that: 1. You may but don't need to make last child absolutely positioned. 2. The last absolutely positioned child will always be on top.
Edit: I've just noticed, this question's discussion has all the answers you could possibly want; more elaborate and better formatted at that.
I have this example for the very known fill-parent height problem: http://fiddle.jshell.net/y9bM4/379/ I've really tried to find a solution by googling but I cannot find anything for these requirements:
The height of the element is not known, neither by percentage nor by absolute size. So position: absolute; top: ?px; bottom: 0px would not work
The upper box should only take up the space it needs for its content, so with my little knowledge about flexbox, it seems that I cannot use it either (just used it in the example because this is kind of as closest as I got)
The outer container has a fixed height (90% of the body in this example)
It would be nice if flex: 1 in each container, is kind of the maximum growth of the upper container. Is this even possible with css yet?
I'm not exactly sure what you're trying to do, but I'm assmuning you would like the second container to use whatever space is left over after the first container is sized to its content.
If so, set the .content class with height:0 and flex-grow:1
UPDATED EXAMPLE:
http://fiddle.jshell.net/y9bM4/385/
I think problem was that you gave the container id height:90%; so it will have to forcefully cover inside it, which is not posibble, So change it with height:auto;.
This will solve your problem
JSFiddle : Updated
CSS : Code to change (Edited)
#container
{
display: block;
position: fixed;
height: 90%;
width:100%;
overflow: hidden;
background: #fff;
border:2px solid green;
}
.content:nth-child(2)
{
position: relative;
display: block;
overflow: auto;
height: 100%;
}
.content{
border:1px solid red
};
.text
{
height: 100%;
display: block;
}
Basically I've got a wrapper to which I've added the (relevant) css properties:
height: 100%; float: left; margin: 10px 10px; position: relative;
with a nested div styled as
display: none;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
width: 100%;
height: 100%;
with display: block; taking effect on hover of the parent, targeting the nested div.
The issue is that when it's hovered, the nested div overlaps the parent by about 4-5px. I can completely eliminate this issue by stating a set height on the parent element, but I would rather keep the height at 100% if possible!

EDIT If you know what's wrong but can't be bothered answering give me a hint and I'll do more research. I'm asking here because I've run out of ideas as to where to look
Thanks very much
The issue is probably that images, because they are inline elements, can add trailing whitespace at the bottom. Generally a fix is to give their parent element a line-height of nothing:
.featured-projectwrap{
line-height:0;
}
But this would mean any text nested would not be visible, so compensate by re-promoting the line-height at the caption level:
.caption{
line-height:1;
}
Here's your fiddle with the changes...
I have a container div (it has both width an height set in pixels).
Is there a way to add a child div that will fill its entire parent but still have margin and or padding ?
suppose the parent div is 200px wide, and 200px high.
if I give the child div a width/height of 100% then it assumes that I mean for the content are to be of size 200px and then if I add padding or margins the size of the child becomes bigger then that of the parent.
I want the child div's content area to be what ever is left after taking out 5px margins on each side...
and please don't tell me to subtract 2*5px from 200px - I know that but I am looking for a better solution.
could it be that css can't handle such a simple task...
You could try the following:
#outer {
width: 200px;
height: 200px;
background: blue;
position: relative;
}
.inner {
position: absolute;
top: 5px;
right: 5px;
bottom: 5px;
left: 5px;
}
demo: http://jsfiddle.net/wYNYh/1/
Set all elements to have box-sizing as border-box in your stylesheet.
This will sum up the padding of all elements so you don't have to worry about any disruptions if you add any padding.
*{
box-sizing: border-box;
}
Something like this: http://jsfiddle.net/Rnf82/ ?
You can set the padding of the outer div. Then the inner div will only occupy what's left.
Have a look at this: (try yourself at jsFiddle)
.outer {
width: 200px;
height: 200px;
background-color: #DD0000;
padding: 5px;
box-sizing: border-box;
}
.inner {
width: 100%;
height: 100%;
background-color: #0000DD;
}
<div class="outer">
<div class="inner"></div>
</div>
really these two ways of doing this is equivalent as far as the question is concerned. It is important to remember the redundancy generated by how html and css standards are setup.
