Fixed div inherit width of relative div - html

I've got a relative div with a width of 40%. After that there is a fixed div that needs to inherit this width.
So I set my html document to this:
<div class="sidebar"></div>
<div class="maincontent">
<div class="fixed--wrapper">
<div class="fixed--header">
</div>
</div>
</div>
And my css:
.sidebar {
width: 20%;
height: 100vh;
overflow: hidden;
position: fixed;
background-color: #000;
color: #fff;
float: left;
}
.maincontent {
float: right;
position: relative;
width: 80%;
background-color: #D00;
height: 300px;
}
.fixed--wrapper {
width: 40%;
position: relative;
float: left;
border-right: 1px solid rgba(0, 0, 0, 0.2);
height: 100%;
overflow-y: scroll;
background-color: #E00;
}
.fixed--header {
height: 60px;
width: inherit;
position: fixed;
z-index: 2;
background-color: #fff;
}
Now the problem arises that my fixed--header is like 8% bigger than the fixed--wrapper. To illustrate this view the following fiddle: https://jsfiddle.net/zj0Lpu0q/1/
I want my fixed--header to be 40% as well.
Sidenote: I know there are quiet the number of questions about this, but I couldn't find one that has a relative div with widths in percentages defined. Therefore I created this new question. If you could link me to another answer I'm happy as well.

Try replacing your css to this
.fixed--wrapper {
width: 40%;
position: relative;
float: left;
border-right: 1px solid rgba(0, 0, 0, 0.2);
height: 100%;
overflow-y: scroll;
background-color: #E00;}
.fixed--header {
height: 60px;
position:absolute;
width:100%;
z-index: 2;
background-color: #fff;}

CSS child element producing a margin the full width of parent

building an overlay containing a stylised container for some text, however this container seems to be producing a margin which when combined with the elements normal width takes up the entire parent element width. According to chrome dev tools its the .flipcontainerelement that is causing this.
It's really weird behaviour and I can't figure out why its behaving in this way.
If I wanted to place content to the right of the container for example, I would not be able to because of this margin being produced.
.flipcontainer {
height: 230px;
width: 150px;
}
.flipcalender {
border: 1px solid #dddddd;
border-radius: 25px;
margin: 0 auto;
margin-top: 0.2px;
background: linear-gradient(white, #f4f2f2);
}
.mmouter {
width: 100%;
height: 100%;
border: 1.5px solid #dddddd;
}
.mmmiddle {
width: 98%;
height: 98%;
}
.mminner {
width: 98%;
height: 98%;
background: linear-gradient(white, #f4f2f2);
position: relative;
}
.mmbreaker {
width: 99%;
background-color: white;
height: 2px;
position: absolute;
z-index: 1;
top: 115px;
}
#mmlightbox {
display: block;
width: 400px;
height: auto;
position: fixed;
top: 30%;
left: 40%;
z-index: 999;
background-color: white;
padding: 10px 20px 10px 0px;
/* margin-right: 239px; */
margin-top: -100px;
margin-left: -150px;
border: solid 2px #f21c0a;
}
<div id='mmlightbox'>
<div class='flipcontainer'>
<div class='flipcalender mmouter'>
<div class='flipcalender mmmiddle'>
<div class='flipcalender mminner'>
<p class='daysremaining'></p>
<p>days</p>
<div class='mmbreaker'></div>
</div>
</div>
</div>
</div>
</div>
Add float: right; to .flipcontainer css like so:
.flipcontainer {
height: 230px;
width:150px;
float: right;
}
Here is the JSFiddle demo
The margin you saw was because you specified the width to '150px'.
Adding float: left removes this and you can add content next to it
.flipcontainer {
height: 230px;
width:150px;
float: left;
}

how to make a <div> column that stretches to height of two <div>s beside it?

Goal: In the content area of a site, I need to make a decorative-only column that spans the height of two divs (containing images) beside it.
Problem: the column either has no height, regardless which attributes I give it, or only has the height of the first sibling div and no fill. I have tried height: 100%, min-height: 100%. Also tried making parent position: absolute and setting top: 0 and bottom: 0.
the code:
.row {
position: relative;
overflow: hidden;
border: #000 3px dashed;
}
#colLeft {
float: left;
width: 15%;
height: 100%;
background-color: red;
}
#B1 {
float: left;
width: 84%;
height: 100px; /* this will actually be the height of the img */
background-color: green;
}
#B2 {
width: 84%;
height: 100px; /* this will actually be the height of the img */
float: left;
background-color: #ff0;
}
<div class="row">
<div id="colLeft"></div>
<div id="B1">
<img src="foo">
</div>
<div id="B2">
<img src="bar">
</div>
</div>
Thanks in advance for your help.

You should change the left column to position: absolute.
.row {
position: relative;
overflow: hidden;
border: #000 3px dashed;
}
#colLeft {
float: left;
width: 20%;
position: absolute;
height: 100%;
background-color: red;
}
#B1 {
float: right;
width: 80%;
height: 100px;
background-color: green;
}
#B2 {
width: 80%;
height: 100px;
float: right;
background-color: #ff0;
}
<div class="row">
<div id="colLeft"></div>
<div id="B1">
<img src="foo">
</div>
<div id="B2">
<img src="bar">
</div>
</div>
In your code you have height: 100px; /* this will actually be the height of the img */ for both img in your .row
You can do it like this also, fiddle http://jsfiddle.net/DIRTY_SMITH/QwZuf/260/
in this example I set the height of 200px to the row and height of 100% to the column
.row {
position: relative;
overflow: hidden;
border: #000 3px dashed;
height: 200px;
}
#colLeft {
float: left;
width: 15%;
height: 100%;
background-color: red;
}
Here's an alternate solution I found that works very well, too.
.row {
display: table-row;
}
#colLeft {
display: table-cell;
width: 15%;
background-color: red;
}
#B1 {
display: table-cell;
width: 84%;
height: auto;
background-color: green;
}
#B2 {
display: table-cell;
width: 84%;
height: auto;
background-color: #ff0;
}

Why does my text div spill out past my container div?

I really need your help,
I can't seem to figure out as to why my div #text spills out past my container div? It should fit nicely inside its container?
Here is the CSS markup:
height: 100px;
width: 500px;
bottom: 50%;
right: 50%;
position: absolute;
display: none;
}
#container {
background: #FFF;
left: 50%;
padding: 10px;
top: 50%;
margin: 0;
padding: 0;
height: 100%;
border: 2px solid rgb(100,139,170);
height: 100%;
position: relative;
}
.topbar {
cursor: pointer;
color: white;
background: rgb(100,139,170);
padding: 4px;
font-weight: bold;
}
#text {
height: 100%;
border: 1px solid red;
}
HTML:
<div id="wrapper">
<div id="container">
<div style="float:left;" class="topbar">Custom Dialog Box</div><div class="topbar" style="text-align: right;">Close</div>
<div id="text"><p>test</p></div>
</div>
</div>
Here is a snapshot of the problem:
The height of #text is 100% which means it gets the height of the containing block, in this case #container. Both the height of #text as well as the #container are 500px. But #text is being pushed down by it's sibling .topbar, causing it to overflow.
To solve this you can use the css property overflow:auto as suggested by Jarred Farrish in the comments
Because #test {height:100%;} it will look for it's parent's height, all the way to #wrapper which is set to height:100px, so #test will get the same height, plus the borders, and the #container doesn't have enough space to hold it (due to the extra blue bar), so it overflows.
I also noticed the layout can be done simpler as follows.
#wrapper {
height: 100px;
width: 500px;
bottom: 50%;
right: 50%;
margin-bottom: -50px; /*half height*/
margin-right: -250px; /*half width*/
position: absolute;
/* display: none; */
}
#container {
background: #FFF;
border: 2px solid rgb(100, 139, 170);
}
.topbar {
cursor: pointer;
color: white;
background: rgb(100, 139, 170);
padding: 4px;
font-weight: bold;
}
#text {
border: 1px solid red;
}
<div id="wrapper">
<div id="container">
<div style="float:left;" class="topbar">Custom Dialog Box</div>
<div class="topbar" style="text-align: right;">Close</div>
<div id="text">
<p>test</p>
</div>
</div>
</div>
You are taking the height of the #container but remember that there is also sort of a header at the top of the container so the text height should be < 100% because you have to substract the height of the dialog header.
Amir got point, the way you can "fix" this is to add padding to content, so you got safe space.
CodePen Sample
<div id="wrapper">
<div id="container">
<div style="float:left;" class="topbar">Custom Dialog Box</div><div class="topbar" style="text-align: right;">Close</div>
<div id="text"><p>test</p></div>
</div>
#wrapper{
height: 100px;
width: 500px;
bottom: 50%;
right: 50%;
margin-right: -250px;
position: absolute;
border: 1px solid yellow;
}
#container {
background: #FFF;
left: 0%;
padding-bottom: 30px;
top: 0%;
margin: 0;
height: 100%;
border: 2px solid rgb(100,139,170);
position: relative;
}
.topbar {
cursor: pointer;
color: white;
background: rgb(100,139,170);
padding: 4px;
font-weight: bold;
border: 1px solid green;
}
#text {
height: 100%;
border: 1px solid red;
}
I also fixed positioning for you.

get non-fixed width div to perfect fit parent without overflowing?

Considering the following code:
<div class='wrapper'>
<div class='right-panel'>Here is the article</div>
<div class='left-panel'>
<div class='left-panel-contents'>
<div class='headline'>
<h1>HEADLINE</h1>
</div>
</div>
</div>
</div>
.wrapper {
height: 200px;
min-width: 960px;
max-width: 1060px;
background: gray;
}
.right-panel {
float: right;
height: 200px;
width: 760px;
background: blue;
}
.left-panel {
background: green;
height: 200px;
}
.left-panel-contents {
position: relative;
background: pink;
height: 100%;
width: 15%;
// how do I make this fill the width of the left panel
}
.headline {
background: black;
color: white;
line-height: 45px;
width: 100%;
position: absolute;
top: 0;
left: 0;
z-index: 1000;
}
h1 {
float: right;
}
http://jsfiddle.net/duw4G/
I'm trying to get the headline text to expand all the way to the right panel. If the left panel contents perfectly filled its parent, this would be possible. If I set it to 100%, overflow: hidden it doesn't solve the problem (the left-panel-contents fill the whole wrapper div width)
Is there any way to adjust my technique to get this to work?
.wrapper {
height: 200px;
min-width: 960px;
max-width: 1060px;
background: gray;
}
.right-panel {
float: right;
height: 200px;
width:75%;
padding:0px;
margin:0px;
background: blue;
}
.left-panel {
background: green;
height: 200px;
width:25%;
padding:0px;
margin:0px;
}
.left-panel-contents {
position: relative;
background: pink;
height: 100%;
width: 100%;
// how do I make this fill the width of the left panel
}
.headline {
background: black;
height: 45px;
width: 100%;
position: absolute;
top: 0;
left: 0;
z-index: 1000;
float:left; position:relative;
}
.headline will be positioned according to the nearest parent with non-static position (i.e. relative or absolute), or to the viewport if no such parent is found.
If it's not required for other purposes, remove position:relative from .left-panel-contents but add it to .wrapper. See: http://jsfiddle.net/duw4G/9/

HTML/CSS: Layout columns don't fill space

I am trying to make a 3-column layout but as you can see from the screenshot below the left-most and right-most columns don't span all the way down:
You can find the code at http://codepen.io/vbelenky/pen/hvbEq and I'm going to paste it here, too:
<div class="wrapper">
<div class="primary">
<div class="primary-left">
Primary Left<br>
blah
</div>
<div class="primary-right">
Primary Right
</div>
</div>
<div class="secondary">
Secondary
</div>
</div>
CSS:
.wrapper {
overflow: hidden;
width: 600px;
border: 1px solid black;
}
.secondary {
width: 200px;
float: left;
background: cyan;
}
.primary {
width: 400px;
float: right;
}
.primary-left {
width: 300px;
float: left;
background: grey;
}
.primary-right {
width: 100px;
float: right;
background: yellow;
}
HTML :
Use follow code that is similar to your query :
<div class="mainDiv">
<div class="left">Left</div>
<div class="center">Center</br>Center<br/>Center<br/></div>
<div class="right">Right</div>
</div>
CSS :
.mainDiv{ position: relative; height: auto;}
.left{ position: absolute;background:red; left: 0; top: 0; width: 100px; height: 100% }
.right{ position: absolute;background:blue; right: 0; top: 0; width: 100px;height: 100%; }
.center{ margin: 0 100px;background:green; }
http://jsfiddle.net/pfqpR/
Like monkhan said, you'll need to set heights for all of the elements, for example (see on CodePen):
.wrapper {
overflow: hidden;
width: 600px;
border: 1px solid black;
height: 40px;
}
.secondary {
width: 200px;
float: left;
background: cyan;
height: inherit;
}
.primary {
width: 400px;
float: right;
height: inherit;
}
.primary-left {
width: 300px;
float: left;
background: grey;
height: inherit;
}
.primary-right {
width: 100px;
float: right;
background: yellow;
height: inherit;
}
The downside of this approach is that you'll need to know what the maximum height is ahead of time (in this case, I picked 40px).
One way to approach this is with absolute positions (instead of floats). It doesn't fit to all needs, but it may fit yours.
http://codepen.io/anon/pen/lLngy
.wrapper {
overflow: hidden;
width: 600px;
border: 1px solid black;
position: absolute; top: 0; left: 0; bottom: 0;
}
.secondary {
width: 200px;
background: cyan;
position: absolute; top: 0; bottom: 0;
}
.primary-left {
width: 300px;
background: grey;
position: absolute; top: 0; left: 200px; bottom: 0;
}
.primary-right {
width: 100px;
background: yellow;
position: absolute; top: 0; right: 0; bottom: 0;
}
One approach that wouldn't require you to set any pre-determined heights would be to apply a 3-colour background image to the wrapper (image height can be 50px and "repeat-y").
This way you will have the background colours of the inner divs repeating all the way down to the bottom and it won't matter which inner div is the tallest.
For example:
.wrapper {
overflow: hidden;
width: 600px;
border: 1px solid black;
background-image: url('3colours.png');
background-repeat: repeat-y;
}
Others said it well. I am just showing another possible way(inconvenient). Inconvenient because it makes the width changing more difficult. Just a background image hack. Use a background image of (wrapper width x 1)px for the .wrapper with colors at appropriate positions. Also remove the background color styles from .secondary, .primary-right and .primary-left.
Here is the fiddle: http://jsfiddle.net/eY9VR/
My coworker gave a solution. The main idea is not to use float property and use display table and table-cell. Please refer to the code for reference. I had to move div.secondary to the top, I commented out the float attribute everywhere, I've declared div.wrapper as display: table and div.secondary, div.primary-left, and div.primary-right as display: table-cell.
