Lately, I've run into a problem when trying to get my web aps to work with small devices. Even then, this doesn't seem to always be an issue, it will depend upon the orientation of the phone. What I'm seeing is say I have a Bootstrap 4 ROW with a col-3 col-6 col-3 setup. The center col has more height and includes images where fade in and out of opacity, so the height is constant. When BS does its thing for smaller displays, the first col-3 breaks properly, leaving space for the col-6. The problem is the col-6 seems to break at the col-3 height and I get over lapping. When using the dev tools, I can see this is the case but I dont want to set a hard height because that makes the spacing go weird and defeats the whole BS purpose. Here are some examples:
<div class="row" style="margin: 0vh 5vw;">
<div class="col-md-3 col-sm-12 text-center wow fadeInLeft">
<div>
<i class="fa fa-eye features-icon"></i>
<h2 style="color: white; font-size: 3vmin">Something</h2>
</div>
</div>
<div class="col-md-6 col-sm-12 text-center wow" style="height: 53vh;">
<img id="img1" src="myImage.jpg" alt="dashboard" class="img-fluid img1" style="margin-top: 3vh;
display:block; position:absolute; opacity: 1;">
<img id="img2" src="~/anotherImage.png" alt="dashboard" class="img-fluid img2" style="margin-top:
3vh; display:block;position:absolute; opacity: 0;">
</div>
<div class="col-md-3 col-sm-12 text-center wow fadeInRight">
<div>
<i class="fa fa-database features-icon"></i>
<h2 style="color: white; font-size: 3vmin">More blah blah</h2>
</div>
</div>
</div>
This image shows where col is over lapping (blue icon)
BTW, I've set the center col height because without it, I get no height to that col. I've tried manipulating it, but it seems that whatever I do, it will fix it for one layout orientation and mess up the others. I must be missing something simple in BS. Thanks in advance for your help.
That row has an inline style defining a margin, maybe the view units are causing the problem. Try changing that around to % or px to see how it behaves or remove that margin all together and use bootstrap's margin utilities. Other thing I can think of would be to try and wrap the overlapping elements in two different .container-fluid
So, I ended up doing what I consider a cheat using jQuery. I gave the col div an id of #mcsCol and put this in my $(document).ready(function)
$("#mcsCol").css({ "height": $("#img1").css("height") });
So essentially, it will check the height of the image and set the col to the same height. If you have a more native solution, I'd love to see it.
How can I solve this problem?
When you add borders to a div, the div is not centered and
the span12 class is not centered.
I would like to center the div with the borders
<div class="row" >
<div class="span12" style="border: 2px solid black">
<div class="row">
<div class="span4">
1
</div>
<div class="span4">
2
</div>
<div class="span4">
3
</div>
</div>
</div>
</div>
Unfortunately, that's what borders do, they're counted as part of the space an element takes up. Allow me to introduce border's less commonly known cousin: outline. It is virtually identical to border. Only difference is that it behaves more like box-shadow in that it doesn't take up space in your layout and it has to be on all 4 sides of the element.

.foo {
outline: 1px solid orange;
}
As of Bootstrap 3, you can use Panel classes:
<div class="panel panel-default">Surrounded by border</div>
In Bootstrap 4, you can use Border classes:
<div class="border border-secondary">Surrounded by border</div>
There's a property in CSS called box-sizing. It determines the total width of an element on your page. The default value is content-box, which doesn't include the padding, margin, or border of the element.
Hence, if you set a div to have width: 500px and 20px padding all around, it will take up 540px on your website (500 + 20 + 20).
This is what is causing your problem. Bootstrap calculates set widths for things just like the above example, and these things don't have borders. Since Bootstrap fits together like a puzzle, adding a border to one of the sides would yield a total width of 501px (continuing the above example) and break your layout.
The easiest way to fix this is to adjust your box-sizing. The value you would use is box-sizing: border-box. This includes the padding and border in your box elements. You can read more about box-sizing here.
A problem with this solution is that it only works on IE8+. Consequently, if you need deeper IE support you'll need to override the Bootstrap widths to account for your border.
To give an example of how to calculate a new width, begin by checking the width that Bootstrap sets on your element. Let's say it's a span6 and has a width of 320px (this is purely hypothetical, the actual width of your span6 will depend on your specific configuration of Bootstrap). If you wanted to add a single border on the right hand side with a 20px padding over there, you'd write this CSS in your stylesheet
.span6 {
padding-right: 20px;
border-right: 1px solid #ddd;
width: 299px;
}
where the new width is calculated by:
old width - padding - border
Depending what size you want your div to be, you could utilize Bootstrap's built-in component thumbnail class, along with (or without) the grid system to create borders around each of your div items.
These examples on Bootstrap's website demonstrates the ease-of-use and lack of need for any special additional CSS:
<div class="row">
<div class="col-xs-6 col-md-3">
<a href="#" class="thumbnail">
<img src="..." alt="...">
</a>
</div>
...
</div>
which produces the following div grid items:
or add some additional content:
<div class="row">
<div class="col-sm-6 col-md-4">
<div class="thumbnail">
<img src="..." alt="...">
<div class="caption">
<h3>Thumbnail label</h3>
<p>...</p>
<p>
Button
Button
</p>
</div>
</div>
</div>
</div>
which produces the following div grid items:
What others have mentioned about border vs border box is definitely correct. You can still get this to work without having to create any custom classes though: http://jsfiddle.net/panchroma/yfzdD/
HTML
<div class="container">
<div class="row" >
<div class="span12">
<div class="row">
<div class="span4"> 1 </div>
<div class="span4"> 2 </div>
<div class="span4"> 3 </div>
</div><!-- end nested row -->
</div><!-- end span 12 -->
</div> <!-- end row -->
</div><!-- end container -->
CSS
.span12{
border:solid 2px black;
background-color:grey;
}
Good luck!
While it's probably not the correct way to do it, something that I've found to be a simple workaround is to simply use a box-shadow rather than a border... This doesn't break the grid system. For example, in your case:
HTML
<div class="container">
<div class="row" >
<div class="span12">
<div class="row">
<div class="span4">
1
</div>
<div class="span4">
2
</div>
<div class="span4">
3
</div>
</div>
</div>
</div>
</div>
CSS
.span12{
-moz-box-shadow: 0 0 2px black;
-webkit-box-shadow: 0 0 2px black;
box-shadow: 0 0 2px black;
}
Fiddle
You can't just add a border to the span because it will break the layout because of the way width is calculate: width = border + padding + width. Since the container is 940px and the span is 940px, adding 2px border (so 4px altogether) will make it look off centered. The work around is to change the width to include the 4px border (original - 4px) or have another div inside that creates the 2px border.
If you need a basic border around you just need to use bootstrap wells.
For example the code below:
<div class="well">Basic Well</div>
If you are using Bootstrap 4 and higher try this to put borders around your empty divs use border border-primary here is an example of my code:
<div class="row border border-primary">
<div class="col border border-primary">logo</div>
<div class="col border border-primary">navbar</div>
</div>
Here is the link to the border utility in Bootstrap 4:

Hello I'm trying to create a navigation bar which is made up of several div containers in one big navigation div.
I'm not sure if my approach is right but I tried to do it like this:
<div id="navigation">
<div class="innen">
<div class="logo">
<img class= "logo" src="logo.png" title="Logo"/>
</div>
<div id="bar">
<!-- Navigation Items are in here --!>
</div>
<div id="gamecard">
<!-- Another right floated Element !-->
</div>
</div>
<div class="unten">
<p>You are here: Main</p>
</div>
</div>
I wanted to push down the bar div to meet the height of the image by using top padding:
#bar{
padding-top: 80px;
}
But now it moves the down gamecard container too. How can I prevent this from happening?
I also added a jfiddle:
http://jsfiddle.net/Cv4p2/
try using position:absolute
<div id="bar" style="position:absolute; padding: 80px 0 0 0">
</div>
Padding is intended to add a cushion inside the container in which you implement it. It appears that you would benefit from using margin. You should replace "padding-top: 80px;" with "margin-top: 80px;" and you would achieve the desired effect.
I have a container div which has text within it that I want centered. I want to also insert a div into the container which floats to the right, like this:
<div id="container" style="text-align:center">
Text
<div id="child" style="float:right"></div>
</div>
Unfortunately what happens is that the text is no longer centered with respect to the container, but is instead shifted to the left by the width of the child.
Does anyone know how to get the text to center whilst keeping the div contained to the right?
Something like this...
<div style='position:relative;'>
my centered text
<div style='position:absolute;right:0;top:0'>
my right div
</div>
</div>
You can obviously throw the inline styles into CSS.
Posibly this?? Creating 3 equal parts. left middle and right??
<div id="container">
<div id="child1" style="float:right width: 30px;"></div>
<div id="child2" style="float:right width: 30px; text-align:center;">TEXT</div>
<div id="child3" style="float:right width: 30px;"></div>
</div>
I need to achieve something like this:
<a style="display:block;" href="#">
<div style="float:left;display:block;">Left</div>
<div>
<div style="display:block;">Right</div>
<div style="display:block;">Right Bottom</div>
</div>
</a>
Basically a button with 2 columns and the right column having 2 rows.
It shows up correctly in modern browsers with inline/block support but in IE6 and IE7, whenever I hover the left div (with float) it'll display as the 'select' text icon instead of the hand icon (i believe once float, block will be cancelled and displayed as inline). Is there any way I can achieve this without using an image as a whole? I need it to be text because it's important for SEO and retina displays.
:( :(
<a href="http://www.google.com/" target="_blank" style="display:block; overflow: hidden" href="#">
<div style="float:left; width:150px;">Left</div>
<div style="float:right; width:150px;">
<div style="display:block;">Right</div>
<div style="display:block;">Right Bottom</div>
</div>
<div style="clear: both;"></div><!-- This will clear the floats for IE -->
</a>
To avoid text cursor add this CSS -
a div{cursor: pointer;}
