Bootstrap 4 custom carousel - html

i'm new to bootstrap and i need some help to make this custom carousel.
The pictures above below will explain perfectly what i'm trying to make!
Thank you!
Desktop view
Mobile view


Here's my solution using JQuery. Make sure to update each image's src attribute to the appropriate value. I've included links to most of the important methods that were used at the bottom of this post.

CodePen
This is not responsive.
If you resize the window to the size of a mobile view, the JQuery function won't be called; however, if the screen starts with a mobile size, the carousel will be appropriate.
If you need the carousel to be updated to the right view during resizing, I believe you can wrap a resize function on the window around the main JQuery function I've used.
e.g.,
$(window).resize(function() {
if( $(this).width() > width ) {
if($(window).width() <= 992)
...
else
...
}

Bootstrap not loading when my html files are in templates folder

I am trying to do my very first own web app with Spring, Thymeleaf and everything seemed to be going well, however after I separated my html files in "templates" folder, since that is required to use thymeleaf, my bootstrap,JS,CSS and all my other resources stopped working.
I have my boostrap included with CDN with the css included in the header and JS,jQuery and popper included in the bottom of the body. I've tried moving the CDN links all in the header, removing my own js and css, however it didn't work.
You can review the html below:

Thank you in advance!

It's best to let thymeleaf handle paths for resources and not use relative ones.
For example set the folowing properties
spring:
web:
resources:
static-locations: classpath:/static/
chain:
strategy:
content:
enabled: true
paths: /resources/**
and then in the html do
<link rel="stylesheet" th:href="#{/css/style.css}"> and
<img th:src="#{/images/person3.jpg}" class="img-thumbnail person_pic">
This way you do not have to add an arbitrary amount of ../ to paths

Gif does not appear when clicking button

This is the code :
<button class="fun" data-toggle="collapse" data-target="emoji">Click For Fun!</button>
<div id="emoji" class="collapse">
<div class="container-fluid padding">
<div class="row text-center">
<div class="col-sm-6 col-md-3">
<img class="gif" src="img/gif/panda.gif">
</div>
</div>
</div>
</div>
The button has the data target set to "emoji" but when I click the button nothing happens.

data-target="#emoji" will solve your problem.
<button class="fun" data-toggle="collapse" data-target="#emoji">Click For Fun!</button>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css">

bootstrap column full height with scrollbar if needed

I have the following (kind of) code :
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" />
<div class="container-fluid" style="min-height: 100vh;">
<div class="row">
<div class="col-8">
<div class="card">
<div class="card-body">
<div class="row">
<div class="col">
header
</div>
</div>
<div class="row">
<div id="logo-frame" class="col d-flex justify-content-center align-items-center">
<img src="https://via.placeholder.com/1000x300" class="img-fluid overflow-auto">
</div>
</div>
<div class="row">
<div class="col">
footer
</div>
</div>
</div>
</div>
</div>
<div class="col-4">
<div class="card">
<div class="card-body">
side
</div>
</div>
</div>
</div>
</div>
The image is of loaded dynamically and can be of any size and aspect ratio.
I want the div #logo-frame to :
take up all vertical space available (the container has min-height: 100vh but I'm not sure how to have the div eat it all up with flexbox) and pad the image with whitespace if required
have the image inside centered horizontally and vertically (I think I got it covered with justify-content-center align-items-center)
show a scrollbar if the height becomes too big to show the image (e.g with https://via.placeholder.com/1000x2000) but only on the image, not on the full page (I think the overflow-auto is enough, but not sure...)
How can I achieve this behavior easily with flexbox ?
Thanks

<div class="row">
<div class="col">

</div>
</div>
<div class="row h-100 overflow-auto">
<div id="logo-frame" class="col d-flex justify-content-center align-items-center">

<div class="col-4">
<div class="card">
<div class="card-body">
side
</div>
</div>
</div>
</div>
</div>
</div>
Can someone help me understand :
if it is possible to not have to cascade down the h-100 ?
why if I put min-height:100vh instead of height:100vh, it does not work ?
why if I don't put d-flex flex-column on the card-body element, it does not work
if there's a better way to make this work ?

Have you considered using the "max-height" css attribute in the parent container in conjunction with an auto scroll on overflow?

How to show multiple horizontal images in Bootstrap card?

How do I place multiple images side by side in a Bootstrap Card?
It should be multiple pictures, but only one title header and description.
In my code, the images start crossing over and intersecting each other.
Eventually, I'd like to use an array of pictures (two or more) and combine them with JavaScript.
The card can be as wide as needed.

You might find Bootstrap's image-fluid class useful.
Images in Bootstrap are made responsive with .img-fluid.
max-width: 100%; and height: auto; are applied to the image so that it scales with the parent element.

Here's your second version with the checkbox.
You might consider using max-width instead of width to keep the card responsive.

How to align button to right in bootstrap 4

I tried looking this up here but I can't find anything related to this specific problem.
I'm trying to make a header which has a button on the left and right of the screen with a logo in the middle, but whenever I make the window smaller or larger the button on the right doesnt stay aligned.
Small window
Large window
Here is the code:
<header>
<div id="container-fluid">
<div class="row">
<div class=" col-2">
Menu
</div>
<div class="col-8 text-center ">
Logo
</div>
<div class="col-2 float-right">
Contact
</div>
</div>
</div>
</header>
What am I missing here?
Thanks in advance.
Fixed it, code now looks like this:
<body>
<header>
<div id="container-fluid">
<div class="row">
<div class="col">
<span class="float-left">Menu</span>
</div>
<div class="col text-center">
Logo
</div>
<div class="col">
<span class="float-right">Contact</span>
</div>
</div>
</div>
</header>
</body>

wrap your content so it can be aligned according to the parent container.

You can use the flex-bootstrap-class and justify-content for this approach:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
<div class="container">
<div class="row d-flex justify-content-between bg-light">
<div class="p-2 bg-dark text-light">
Menu
</div>
<div class="p-2 bg-dark text-light">
Logo
</div>
<div class="p-2 bg-dark text-light">
Contact
</div>
</div>
</div>

You havn't defined what size of column grid you are using. Using col-xs,col-sm, col-md,col-lg will have different effects for the particular code. Run the snippet code in full page below and see how the col-size affects when the browser is resized.
Update - Bootstrap 4 has replaced the col-xs with col- .
