I am working on a grid layout using css flex styling and want a total css solution, if possible, I have the means to fix it with javascript.
When a row exceeds the viewport width, it displays the scrollbar,
but when you scroll, the styling of the row element remains the size of the viewport,
it does not seem to "wrap" all of its children.
see : fiddle
Try scrolling, you will see the yellow row (.sk_row) class does not appear around all its children.
A solution would be fine, but I would like to know why the parent does not visually contain all children. I think I may be missing some key concept about flexboxes...
Duplicate of fiddle code...
<body>
<div id='pg_wrap'>
<div id='frm0'>
<div class='sk_scrl'>
<div class='sk_row'>
<div class='itm_val'>row 1</div>
<div class='itm_val'>1</div>
<div class='itm_val'>2</div>
<div class='itm_val'>3</div>
<div class='itm_val'>4</div>
<div class='itm_val'>5</div>

</div>
#frm0{ width:420px;height:200px}
.sk_scrl{ overflow:auto;display:flex;flex-flow:column;align-content:stretch}
.sk_row{
display:flex;
justify-content:flex-start;
align-items:center;
background:#ff0;border:2px #f00 solid;
height:50px}
.itm_val{
display:flex;
border:1px #000 solid;background:#666;
flex:0 0 100px; height:30px; margin:0 5px;
align-items:center;justify-content:center}
Note : this is not the same as question
That op wants to change child behaviour, I want the parent to change.
It's not working the way you want because .sk_row inherits the width, in this case from #frm0:
#frm0 { width: 420px; }
With the class .sk_scrl you can't see it very well, because it's set to:
.sk_scrl { overflow: auto; }
If you use your browsers developer tools (assuming you have any), you'll see that the elements wrapped around your .itm_val divs are all 420 pixel wide. The reason the .itm_val divs are all visible outside of their container, is because they are "overflowing" out of their containing div.
Here's an example for how the width-inheriting-thing works:
<div class="container">
<div class="element"></div>
</div>
If you set the the width of .container to 50%, it will use up half of the available width within the window. If, however, you want .element to take up the full width of the window, you will have to adjust the width like this:
.element {
width: 200%;
}
If it were set to 100%, it would only be as wide as .container.

Basically, I need to put a back-to-top button at the right side of the footer.
Something like this:
What I get is this:
You can see that there is a blank space between footer and the end of viewport, that space is the height the back-to-top button, if I remove the button the blank space is removed too.
I'm using bootstrap so my html code is similar to:
<footer class="container-fluid">
<div class="container">
<div class="content1>CONTENT 1</div>
<div class="content2>CONTENT 2</div>
</div>
<div class="back-to-top>TOP</div>
</footer>
You can see an example in Bootply. You can see that the footer has to be 20px height (min-height: 20px) but instead it is 40px.
I think that my problem will be solved if I can put the .back-to-top div beside the .container div.
How can I get this?
You can use helper class pull-right and move TOP link before container:
<footer class="container-fluid">
<div class="back-to-top pull-right">TOP</div>
<div class="container">
<div class="content1>CONTENT 1</div>
<div class="content2>CONTENT 2</div>
</div>
</footer>
You need to remove your CSS bloc:
.back-to-top {
float: right;
position: relative;
top: -20px;
}
Doc: http://getbootstrap.com/css/#helper-classes-floats
Having a min-height proxy doesn't mean you footer is going to be 20px. That just mean its height won't be smaller than that. If you want your height to be 20px, use height property. If for some reason you want it to be variable, you can look to the max-height property.
For your "back-to-top" button, here is my suggestion :
http://jsfiddle.net/Bladepianist/38ne021p/
HTML
<footer class="container-fluid navbar-inverse">
<div class="row">
<div class="col-xs-6">CONTENT 1</div>
<div class="col-xs-5">CONTENT 2</div>
<div class="col-xs-1 text-right" id="back-to-top">TOP</div>
</div>
</footer>
CSS
.container-fluid {
color: white;
}
Basically, I change your "back-tot-top" class to an ID in my model but you're free to adapt it to your liking.
Using the col-system and the text-positions classes, you can achieve the same rendering as you show in your question. That way, the back-to-top button is part of the footer.
Hope that's helping ;).
I need to split window in to the 2 horizontal divs by height:50%; width:100%:, is it possible with bootstrap? Tried like this:
<div class="container-fluid">
<div class="row">
<div class="col-lg-12" style="border:1px solid red">
1
</div>
<div class="col-lg-12" style="border:1px solid red">
2
</div>
</div>
</div>
With green matched how it should be...
Just a suggestion calculate the height of the .row div dynamically using javascript. CSS height:50% will only work if the parent div is given some height.
EG: .row{ height:500px; } will work fine.
But calculate this height using jQuery function $(window).height().
Assuming this is your only markup you can give each parent element a height of 100%:
body,html {
height: 100%;
}
.container-fluid {
height: 100%;
}
.row {
height: 100%;
}
.col-lg-12 {
height: 50%;
}

Not sure why you would need to have 2 boxes with no content containing set heights?
Surely the rational thing to do is fill it with content first, then add padding to your divs to make the design the way you want it.
Adding heights to an empty div is asking for trouble early in your build stage.
Simply add 1 x id to each col-lg-12 as shown below:
<div class="col-lg-12" id="topContent" style="border:1px solid red">
1
</div>
<div class="col-lg-12" id="bottomContent" style="border:1px solid red">
2
</div>
Now when you finished adding content simply reference the ID and add padding top or bottom to your id and you will find it is a lot simpler to code going forward. Trying to mess with set heights early really is looking for problems if going responsive.
I am trying to contain a div's borders within its parent div, and I would like the overflow text from the child div to automatically put a scroll-bar on the child div. I have tried everything that I can think of, but I do not know of a way to do that which I am trying to do. Could someone please offer me some advice on how to do this as efficiently as possible?
My parent div has a percentage-defined height though
This should not be a problem, as long as parents has an height that has a valid value.You can set a height or a max-height width a percentage value.
max-height, will let it grow untill it matches the max value.
http://jsfiddle.net/E2Mfa/
For instance this style sheet:
html, body, .childContainer1 {
height:100%;
background:#edf;
}
body, div, p {
margin:0;
}
.parentContainer {
height:25%;
background:#fed;
}
.childContainer1 {
overflow:auto;
}
.childContainer2 {
max-height:100%;
background:#def;
overflow:auto;
}
If you remove height from html or body, it doesnt work anymore.
When you give percentage height, it calculates it from its parent height.
If no height found in CSS parent, then there is no value to calculate from.
max-height returns no values avalaible to calculate a percentage height for the childs
The structure used here :
<div class="parentContainer">
<div class="childContainer1">
...
</div>
</div>
<div class="parentContainer">
<div class="childContainer2">
...
</div>
</div>
<div class="parentContainer">
<div class="childContainer1">
...
</div>
</div>
<div class="parentContainer">
<div class="childContainer2">
...
</div>
</div>
Does your parent div have an absolute size? If it does you could so something like this:
<div style="width:100px;height:100px;">
<div style="position:absolute;overflow:auto;border:solid black 1px;">My Content</div>
</div>
Check this (not sure wether you want something like this),
<div class="outer-div">
<div class="inner-div">Test content Test content Test content Test content Test content Test content Test content Test content Test content Test content</div>
</div>
.outer-div {
width :200px;
height :100px;
border: 1px solid gray;
}
.inner-div {
width :50%;
height :75px;
border: 1px solid black;
overflow: auto;
}

I have some divs that should take the entire height of a page. I managed to get this working as i needed. (Some fixed rows and some flexible rows) like in a html table.
I took the solution from one of my other questions here:
Layout divs in css like table cells in HTML Tables
Today i had to add a div inside the flexible row which should take 100% of the height of the flexible row. Which works great in all major browsers. Muahaha that was a good joke wasn't it? Of course this doesn't work as expected in IE see my js fiddle:
<div class="tableContainer">
<div class="row rowA">
<div class="cell">Test</div>
</div>
<div class="row rowB">
<div class="cell">Test</div>
</div>
<div class="row rowC">
<div class="cell">Test</div>
</div>
<div class="row rowD">
<div class="cell testcell">
<div class="testcontent">Test</div>
</div>
</div>
<div class="row rowE">
<div class="cell">Test</div>
</div>
</div>
http://jsfiddle.net/7ewEJ/3/
the ie seems to take the "100%" from the page and not from the enclosing flexible table row. So the blue div should take the whole space of the purble table row.
Am i doing anything wrong?
Could this be a bug in ie's height calculation?
http://jsfiddle.net/7ewEJ/5/
div.testcell{
height: 100%;
width: 100%;
min-width: 1px;
min-height: 1px;
/*background: #fff;*/
align: center;
display: block;
}

I tried like all combinations:
<div class="row">
<div class="span7 offset5"> box </div>
</div>
or
<div class="container">
<div class="row">
<div class="span7 offset5"> box </div>
</div>
</div>
changed span and offset numbers...
But I cant get a simple box perfectly centered on a page :(
I just want a 6-column-wide box centered...
edit:
did it with
<div class="container">
<div class="row" id="login-container">
<div class="span8 offset2">
box
</div>
</div>
</div>
But the box is too wide, is there any way I can do it with span7 ?
span7 offset2 gives extra padding to the left span7 offset3 extra padding to the right...
Bootstrap's spans are floated to the left. All it takes to center them is override this behavior. I do this by adding this to my stylesheet:
.center {
float: none;
margin-left: auto;
margin-right: auto;
}
If you have this class defined, just add it to the span and you're good to go.
<div class="span7 center"> box </div>
Note that this custom center class must be defined after the bootstrap css. You could use !important but that isn't recommended.
besides shrinking the div itself to the size you want, by reducing span size like so... class="span6 offset3", class="span4 offset4", etc... something as simple as style="text-align: center" on the div could have the effect you're looking for
you can't use span7 with any set offset and get the span centered on the page (Because total spans = 12)
Bootstrap3 has the .center-block class that you can use. It is defined as
.center-block {
display: block;
margin-left: auto;
margin-right: auto;
}
Documentation here.
If you want to go full-bootstrap (and not the auto left/right way) you need a pattern that will fit within 12 columns e.g. 2 blanks, 8 content, 2 blanks. That's what this setup will do.
It only covers the -md- variants, I tend to snap it to full size for small by adding col-xs-12
<div class="container">
<div class="col-md-8 col-md-offset-2">
box
</div>
</div>
Sounds like you just wanted to center align a single container.
The bootstrap framework might be overcomplicating that one example, you could have just had a standalone div with your own styling, something like:
<div class="login-container">
<!-- Your Login Form -->
</div>
and style:
.login-container {
margin: 0 auto;
width: 400px; /* Whatever exact width you are looking for (not bound by preset bootstrap widths) */
}
That should work fine if you are nested somewhere within a bootstrap .container div.
add the class centercontents
/** Center the contents of the element **/
.centercontents {
text-align: center !important;
}
#ZuhaibAli code kind of work for me but I changed it a little bit:
I created a new class in css
.center {
float: none;
margin-left: auto;
margin-right: auto;
}
then the div become
<div class="center col-md-6"></div>
I added col-md-6 for the width of the div itself which in this situation meant the div is half the size, there are 1 -12 col md in bootstrap.
Follow this guidance https://getbootstrap.com/docs/3.3/css/
Use .center-block
.center-block {
display: block;
margin-left: auto;
margin-right: auto;
}
wrap the div in a parent div with class row then add style margin:0 auto; to the div
<div class="row">
<div style="margin: 0 auto;">center</div>
</div>
