Bootstrap4 columns containing absolutely positioned elements - html

I have been working on a game and, for certain things, I used absolute positioning. In particular, I need it for some moving animations where I have to slide elements around and overlap them to create an effect.
I'm trying to work on making the game good-looking on mobile, and I've been running into some problems caused by Bootstrap columns that contain those absolutely positioned elements.
This is the look I'm trying to get (aside from the badly aligned number), notice the red squared row in the middle:
The whole center part of the screen (the row with buttons, emojis, and the centered card icon underneath) is a row containing cols. This is some of its markup
<div class="col order-1 order-xl-1 col-4 col-xl-2">
<div style="display:inline-block">
<p class="backgrounded-text" style="white-space: nowrap; text-overflow: ellipsis;"><span id="turn_elem">...</span></span></p>
<p class="backgrounded-text">Carta attuale: <span id="curr_card"><img class="card_icon" /></span></p>
</div>
</div>
<div class="reaction_box order-2 order-xl-2 col col-4 col-xl-2">
<span style="padding-left:5px!important;padding-right:5px!important" class="reaction_title">Reazioni:</span>
<table>
<!-- emojis ... -->
</table>
</div>
<div class="col order-5 order-xl-3 col-12 col-xl-3">
<span>...</span><br />
<span id="hidden_card">
<img class="card_placeholder" src="..." />
</span>
<span id="card_stack" class="slide_to_right">
<img class="card_placeholder" src="..." />
</span>
<div id="stacked_card">
<img id="stacked_front" class="card_placeholder" src="..." />
</div>
<div id="hidden_uncovered_card_div">
<img id="hidden_uncovered_card" class="card_placeholder" src="..." />
</div>
</div>
<div class="col col-4 order-3 order-xl-4 col-xl-3">
<button style="width: 49%" class="btn btn-lg btn-dark" id="doubt" #click="doubt()" :disabled="playing_animation">Dubito!</button>
<button style="width: 49%" class="btn btn-lg btn-dark">
Metti giĆ¹
</button>
</div>
</div>
The img that has id hidden_card is a card to the left of the red one that is made visible and slides to the right to cover that (it uses jQuery animate to manipulate the position). On top of stacked_card, which is the main red card that's displayed in the screenshots, there's another copy of it, that is flipped with jQuery and moved to the right to overlap hidden_uncovered_card. This is pretty much how the animations work. They all depend on using position: absolute and manipulating the positioning.
For some reason, the actual look I'm getting with the above code is this:
There is some space in between the three columns on the top and the one containing the red card back, and I don't understand where it is coming from.
Removing all the position: absolute seems to fix this, but of course, then all the animations that depend on it stop working.
Is there any way to fix this positioning without removing the position: absolute? It'd be a pain to have to rewrite the code for all the animations, as it's working perfectly on desktop.
Here's a static webpage that contains the markup. You can turn it to mobile view (the screenshots were taken as iPhone 6/7/8 mode) and see for yourself.

The actual app (a beta version, that is) can be found here, in case you wanted to see how the animations work. If you need any additional information, just let me know.

Bootstrap is using a 12 colums grid.
Check how you use them.
You have:
<div class="col order-1 order-xl-1 col-4 col-xl-2">The two button on the left<div>
<div class="reaction_box order-2 order-xl-2 col col-4 col-xl-2">the emojis</div>
<div class="col order-5 order-xl-3 col-12 col-xl-3">the red cards</div>
<div class="col col-4 order-3 order-xl-4 col-xl-3">the three button on the right</div>
You should clean that!!!
Example:
col followed by col-4 is the same as just col-4 where col-4 overrides col.
order-1 and order-xl-1 is redondant if there is no order-md-3 (for example)
Just order-1 is enought here.
For these 4 divs, make sure you use the 12 grid spaces correctly.
So about the col and col-* usage, for mobile size, you actually have 24 spaces used out of 12.
4 spaces
4 spaces
12 spaces
4 spaces
And whent the col-xl-* applies, you have 10 spaces used out of 12. Is that on purpose?
2 spaces
2 spaces
3 spaces
3 spaces
So here is what I suggest for a start:
<div class="col-3 col-xl-2 order-1">The two button on the left<div>
<div class="reaction_box col-4 col-xl-2 order-2">the emojis</div>
<div class="col-2 col-xl-3 order-3">the red cards</div>
<div class="col-3 order-4">the three button on the right</div>
which doesn't change the xl size at all, but produces this (iphone 6/7/8 mode):
That's a start.
So the trick is to have the classe in order... All the col-* from default to the bigger specific size... And then the order-* in order too. That make the markup readable.
;)
EDIT
To have the red cards looking like on another row :
<div class="col-4 col-xl-2 order-1">The two button on the left<div>
<div class="reaction_box col-4 col-xl-2 order-2">the emojis</div>
<div class="col-10 col-xl-3 order-4 order-xl-3 sm-translateUp">the red cards</div>
<div class="col-4 order-3 order-xl-4">the three button on the right</div>
Notice the order changed and that there is an additional .sm-translateUp class which would be:
#media screen and (max-width: 576px){
.sm-translateUp{
transform: translateY(-85px);
}
}
That makes:
Now that really looks like a hack... (LOL) But since that col is trapped inside its parent .row, that is all I think of for the moment.
So have that class defined inside all necessary #media rules for each bootstrap break points:
sm: >= 576px
md: >= 768px
lg: >= 992px
xl: >= 1200px

Aligning Images side-by-side with columns in bootstrap 4

I am using Bootstrap 4, and trying to align my columns so that I have 2 images next to each-other on medium or larger viewports, but they keep aligning themselves one on top of the other.
<div class="row">
<div class="col-6">
<img class="img-fluid"
src="img/1.PNG">
</div>
<div class="col col-5 d-none d-md-block">
<img class="img-fluid"
src="img/2.PNG">
</div>
</div>
Image of code and example
That should work just fine if you take all the extra bits from the Row classes and just have class="row" Your column widths are both set to 5 though, 6 would be ideal for centering.
To assist with sleeker code, on the img classes try removing it all except for img-fluid
Your column classes are wrong. col fills all available space, and col-5 takes 5 columns on all screens. And in this case your col-5 is overriding your col anyway. What you actually need to do:
Use col-md-6 on both the images in place of col col-5. Your images will align themselves side by side from medium and up.
Also, you do NOT need to add d-none d-md-block to the parent and all the child classes. If you don't want to show a particular div in less than md, using it on the parent is enough.
For demonstration purposes I went ahead and used a dummy image that I could get to work. Your structure should be as follows.
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap#4.6.0/dist/css/bootstrap.min.css" integrity="sha384-B0vP5xmATw1+K9KRQjQERJvTumQW0nPEzvF6L/Z6nronJ3oUOFUFpCjEUQouq2+l" crossorigin="anonymous">
<div class="row">
<div class="col-6 col-lg-6 col-sm-6">
<img src="https://dummyimage.com/600x400/000/fff">
</div>
<div class="col-6 col-lg-6 col-sm-6">
<img src="https://dummyimage.com/600x400/000/fff">
</div>
</div>
Using the different Large, Medium, and Small bootstrap classes allows for your row to adjust on different screen sizes, while maintaining that row structure. This link here is also very helpful for learning the system.

How to set bootstrap column for mobile screen, medium screen

for medium screen
|-----(1)||-----(2)|
for mobile screen iphone x
|---------------(2)|
|-----(1)|
in first scenario both (1) and (2) have same column size in single line,
but in second scenario (1) and (2) both have in different line,
<div class="row">
<h3 class="col-7 col-md-6" >(1)</h3>
<h3 class="col-12 col-md-6" >(2)</h3>
</div>
but in second scenario (mobile screen) i am facing difficulty to set column, can any one help me for second scenario.
[Edited]
Flex is the solution :)
You can use flex properties to make it easier, they're a little tricky at the beginning but very effective.
Example
<link href="https://cdn.jsdelivr.net/npm/bootstrap#5.0.0-beta3/dist/css/bootstrap.min.css" rel="stylesheet"/>
<div class="m-5">
<h2>Option</h2>
<div class="w-50 d-flex flex-column-reverse flex-md-row">
<h3 class="col-7 col-md-6 border border-dark">(1)</h3>
<h3 class="col-12 col-md-6 border border-dark">(2)</h3>
</div>
</div>

Remove empty space between content in column and the edge of column

<div class="row mt-5 d-flex">
<div class="col-md-3 p-5 mt-3">
<img id="image" class="align-self-center"
src="background1.jpg"
width="80%" height="100%"/>
</div>
<div class="col-md-4 align-self-center">
<span id="text">
text
</span>
</div>
<div class="col-md-5 background-image">
</div>
</div>
Result:
I don't know why the empty space between the rounded image and the end of column is there. I use bootstrap. I've put borders around divs with "col-md-*" in order to see the edges correctly.
I tried setting padding and margin to 0 but there weren't any changes. I think it has to do something with the "img" tag (I also tried setting it to be displayed as a block).
Check for any padding or margin. usually bootstrap adds those properties automatically with col-md-** classes. You might have to override those classes. I would use the inspect element tool to track them.

Bootstrap Column Reordering Sizing Problems

I'm trying to reorder the columns on my website via Bootstrap's method of reordering columns depending on the screen size which works fine for most of the responsive layouts I'm testing apart from 1.
The layout having problems is the Tablet Landscape Layout (1024 x 768) which displays like this:
Every other screen displays the blue div and the right div either with the red div on top if the screen is too small or on the right with the blue div aligning itself exactly next to it if the screen is large enough.
This is the code I'm using right now:
<div class="container">
<div class="col-xs-12 col-sm-12 col-md-12 col-lg-12 col-xl-12">
<div class="row clearfix">
<div class="col-xs-12 col-sm-12 col-md-push-8 col-md-4 col-lg-push-8 col-lg-4 col-xl-push-8 col-xl-4" style="background: red">
Basket
</div>
<div class="col-xs-12 col-sm-12 col-md-pull-8 col-md-8 col-lg-pull-4 col-lg-8 col-xl-pull-8 col-xl-8" style="background: blue">
News
</div>
</div>
</div>
</div>
Does anyone know why the blue div is so far to the right on the Tablet Landscape layout rather than touching the red div like it should?
Some general markup issues:
First of all, there's no col-xl-*, so you can get rid of those.
Secondly, you don't need col-xs-12, since the default is for it take up the whole width unless otherwise specified.
Third, Bootstrap is mobile first, so larger sizes will override the existing smaller sizes, meaning if you don't intend on changing something, there's no need to specify the larger size again.
The actual issue is that col-*-pull-* is relative to where the element would be placed. Bear in mind, you haven't changed anything in the document flow. So the elements are positioned normally and then phase shifted with left or right. Since the blue container would normally start 4 columns over, you only need to pull it back by 4 columns, instead of 8.
The whole thing can be rewritten like this:
.red { background: red }
.blue { background: blue }
<link href="//cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.2/css/bootstrap.css" rel="stylesheet"/>
<div class="container">
<div class="row ">
<div class="col-md-4 col-md-push-8 red"> Basket </div>
<div class="col-md-8 col-md-pull-4 blue"> News </div>
</div>
</div>

Bootstrap right Column on top on mobile view

I have a Bootstrap Page like this:
<div class="row">
<div class="col-md-6">
A
</div>
<div class="col-md-6">
B
</div>
</div>
Looks like:
-----
|A|B|
-----
So if I look at it on a mobile Device, the Column A is on top, but I want the B on top.
Is this possible?
I tried it with push an pull, but it didn't work.
Use Column ordering to accomplish this.
col-md-push-6 will "push" the column to the right 6 and col-md-pull-6 will "pull" the column to the left on "md" or greater view-ports. On any smaller view-ports the columns will be in normal order again.
I think what throws people off, is that you have to put B above A in your HTML. There may be a different way to do this where A can go above B in the HTML, but I'm not sure how to do it...
DEMO
<div class="row">
<div class="col-md-6 col-md-push-6">B</div>
<div class="col-md-6 col-md-pull-6">A</div>
</div>
view-port >= md
|A|B|
view-port < md
|B|
|A|
It's worth noting that if you are using columns that are not both equal to 6, then the push amount will not equal the initial column size.
If you have 2 columns (A & B) and wish for column A to be smaller and to the right on "sm" or greater viewports, but atop a mobile (xs) viewport, you would use the following:
<div class="row">
<div class="col-sm-4 col-sm-push-8">A</div>
<div class="col-sm-8 col-sm-pull-4">B</div>
</div>
Otherwise, the alignment of the columns will appear off.
Flexbox Direction
For Bootstrap 4, apply one of the following to your .row div:
.flex-row-reverse
For responsive settings:
.flex-sm-row-reverse
.flex-md-row-reverse
.flex-lg-row-reverse
.flex-xl-row-reverse
In Bootstrap 4, let's say you want to have one order for large screens and a different order for smaller screens:
<div class="container">
<div class="row">
<div class="col-6 order-1 order-lg-2">
This column will be ordered second on large to extra large screens
</div>
<div class="col-6 order-2 order-lg-1">
This column will be ordered first on large to extra large screens
</div>
</div>
</div>
You can omit order-1 and order-2 above. Just added for clarity. Default order will be the order the columns appear in the html.
For more info https://getbootstrap.com/docs/4.1/layout/grid/#reordering
The below code work for me
.row {
display: flex;
flex-direction: column-reverse;
}
This is now done (in Bootstrap v4) by adding order-# classes.
See https://getbootstrap.com/docs/4.1/migration/#grid-system-1
Like this:
<div classname='col-md-8 order-2'>...</div>
<div classname='col-md-4 order-1'>...</div>
I have three bootstrap 4 columns of different sizes. As the screen gets smaller the third column is hidden, then when the screen gets smaller still and the divs are stacked the order changes so that column 2 is at the top.
<div class="col-xs-12 col-sm-4 col-md-3 order-2 order-sm-1">
<h3>LEFT HAND SECTION</h3>
<p>For news, links photos or comments.</p>
</div>
<div class="col-xs-12 col-sm-8 col-md-5 order-1 order-sm-2">
<h3>MAIN SECTION</h3>
<p>The main content for the page.</p>
</div>
<div class="col-xs-12 col-md-4 d-none d-md-block order-last">
<h3>BLANK SECTION</h3>
<p>Will usually just be blank.</p>
</div>
I hope this helps. I found it difficult to understand this but finally got there with the help of this thread, but it was a bit hit and miss.
I used:
.row {
display: flex;
flex-direction: row-reverse;
}
This worked for me on Bootstrap 4:
<div class="container-fluid">
<div class="row">
<div class="col-md-4 order-md-last">
<%= render 'form'%>
</div>
<div class="col-md-8 order-md-first">
CONTENT
</div>
</div>
</div>
Bootstrap 4 includes classes for flex.
See: https://getbootstrap.com/docs/4.3/layout/utilities-for-layout/
<div class="row flex-column-reverse flex-md-row">
<div class="col-sm-10">
Col 1
</div>
<div class="col-sm-2">
Col 2
</div>
</div>
In Bootstrap V4 (Released January 18, 2018) You can use Reordering Classes. Info here under Reordering tab.
