Bootstrap 4: Not being able to vertically -and responsively- center an image - html

I'm working on an Angular 6 app and at this moment I'm trying to center an image on home screen but no matter which solution I try (from the ones I've found here) it always shows immediately next to top navbar and not vertically centered.
I tried all solutions found in this next post in app.component.html with no luck, always get the more or less the same result as can be seen in the picture:
Vertical Align Center in Bootstrap 4
Please, help me in centering vertically home image (or text or whatever I choose to put) without affecting the rest of pages that use the app.component.html template.

}


You probably missunderstood the solution given in the vertical align post.
To be able to align vertically an item depending on its parent, you have to set the parent's height (that is why you see body height:100% in their example) but if, like in your html, you have many different parents, not only the parent has to have the 100% height prop, but also the children props
CSS Example :
#import "~bootstrap/dist/css/bootstrap.min.css";
#import "~font-awesome/css/font-awesome.css";
html, body, div {
height: 100%;
}
HTML Example :
<body>
<div>
<image>the centered element</image>
</div>
</body>


After researching and doing a lot of trial and error I came up with a solution that works. I hope it is useful for anyone else with this issue.
My app main template consists on an horizontal navbar header => content => horizontal navbar footer and I set a fixed height footer of 40 px so then I use a negative margin of 40px for home image so it is centered respect content div and not the whole screen (I don't like this approach very much -I mean, using negative margins- but it works):
app.component.html (the main structure):
<div class="main">
<div class="row header m-0 p-0">
<div class="col-12 m-0 p-0">
<app-nav></app-nav>
</div>
</div>
<div class="row content m-0 p-0">
<router-outlet></router-outlet>
</div>
<div class="row footer">
<app-footer></app-footer>
</div>
</div>
home.component.html:
<div style="margin-top: -40px !important;" class="pl-5 pr-5">
<img src="../../../assets/img_home.png" class="img-fluid" />
</div>
styles.css:
html, body {
height: 100%;
}
.main {
display: flex;
flex-flow: column;
height: 100%;
}
.main .row.header {
flex: 0 1 auto;
}
.main .row.content {
flex: 1 1 auto;
}
.main .row.footer {
flex: 0 1 auto;
}
And so is how the home screen looks:

Nav pills dynamic layout issue

I have 2 nav pill buttons that are supposed to change the layout when clicked. Both layouts include the sidebar which doesn't change.
Nav pill 1 changes the layout to:
sidebar | column 1 | column 2
Nav pill 2 changes the layout to:
sidebar | col 1 | column 2 | col 3
Right now what happens is that one column will show up next to the sidebar but the others will be under it and i'm not sure why this happens
#sidebar {
/* width: 250px; */
min-height: 100vh;
max-height: 100vh;
}
#sidebar_sub_header a {
border-radius: 0;
}
#sidebar_main_content::-webkit-scrollbar {
width: 0;
height: 0;
overflow-y: scroll;
scrollbar-width: none;
-ms-overflow-style: none;
overflow-x: hidden;
}
#sidebar_main_content img {
/* border: 1px solid white; */
border: 1px solid rgba(255, 255, 255, 0.1);
height:100px;
width:100px;
}
#sidebar_footer {
align-items: center;
text-align: center;
}
#main_body_channels {
height: 100vh;
}
#main_body_token_requirement_confirmation {
height: 100vh;
}
#main_body_roles {
height: 100vh;
}

using bootstrap 5.3.0 alpha-1

For Bootstrap tabs to work every tab-pane needs to be wrapped in a tab-content container.
For your columns; add the class container-fluid to each tab-pane, then add a row that contains your columns. In my basic example all columns are equal in width, but its easily adjustable.
I am assuming you want a full-page layout, so in CSS do:
#sidebar,
main {
height: 100vh;
max-height: 100vh;
}
Then give each container-fluid in <main> the class h-100, which is equal to height: 100%.
Next, give each row the class h-100. Add flex class align-items-stretch to make each column stretch the full available height.
Note: This snippet is build upon my answer of your previous question, not upon the code in your question.
#sidebar,
main {
height: 100vh;
max-height: 100vh;
}
.tab-pane .row .col {
background: tomato;
}
.tab-pane .row .col:nth-child(2) {
background: lightyellow;
}

Sticky navbar only is sticky for first section of page

So I am creating a bootstrap website. It is supposed to be a one-page website and I have a navar at the top. My navbar is only sticky for the first section and then it just entirely disappears. How do I make it continue to stay sticky so that when I scroll through the entire page comes along at the top?
Here is my current code:
body,
td,
th {
font-family: muli;
font-style: normal;
color: #000000;
}
body {
min-height: 100%;
width: 100%;
argin-left: 0px;
background-image: url();
background-color: #FFFFFF;
}

You can remove the sticky-top class and just add header{position:sticky;} in css as there is some particular javascript which hides your header after first section.

Add 'fixed-top' in the nav tag
and remove the " sticky-top" from header tag

Bootstrap 4 Carousel 3 items move advance 1

Sorry to be a pain. I might have been staring at my code for way to long but I am trying to implement a Bootstrap Carousel into my website that will show 3 and then progress one. I am currently following the code sniper at: https://www.codeply.com/go/EIOtI7nkP8 but can only get it to show one and progress one at a time.
Any help would be most appreciated.
Many thanks,

Your script for the Carousel is using jQuery, but it's trying to run before jQuery is loaded by the page. In its current state you need to move the Carousel script to AFTER the jQuery loading.
<!-- Bootstrap core JavaScript -->
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.bundle.min.js"></script>

<script src="grayscale.min.js"></script>
<script>
$('#recipeCarousel').carousel({
interval: 10000
})
$('.carousel .carousel-item').each(function(){
var minPerSlide = 3;
var next = $(this).next();
if (!next.length) {
next = $(this).siblings(':first');
}
next.children(':first-child').clone().appendTo($(this));
for (var i=0;i<minPerSlide;i++) {
next=next.next();
if (!next.length) {
next = $(this).siblings(':first');
}
next.children(':first-child').clone().appendTo($(this));
}
});
</script>
Now the jQuery functions correctly and it moving like you desire.
I downloaded the JS and CSS for grayscale and linked to the CDNs of the libraries to confirm this would work for you.

Bootstrap - How to get card vertically centered between search bar and bottom of the viewport?

I'm trying to get a card to be vertically centered between the search bar and the bottom of the viewport.
I've tried to make the body height 100%, but then it extends past the viewport and the user is able to scroll down into whitespace. I've tried to use align-content: center; on the parent container, but it doesn't change anything.
html.html
<body>
<div class="navbar navbar-expand-lg sticky-top">
<!-- nav info -->
</div>
<div class="container-fluid">
<!-- Title above search bar -->
<div class="row">
<div id="search-title" class="col-xl-6 col-md-7 col-sm-8 col-8 mx-auto">
<h3>Title</h3>
</div>
</div>
<!-- Search bar -->
<div class="row">
<div class="col-xl-6 col-md-7 col-sm-8 col-8 mx-auto">
<!-- search form -->
</form>
</div>
</div>
<!-- No results -->
<div class="row">
<div id="no-results" class="col-xl-6 col-md-7 col-sm-8 col-8 mx-auto">
{% if term != '' and not cameras %}
<!-- if no results then tell user -->
{% endif %}
</div>
</div>
<!-- Resulting card from search -->
{% if camera %}
<div class="container align-center">
<!-- I would like this card to be vertically centered between the search bar and the bottom of viewport -->
<div class="col-xl-6 col-md-7 col-sm-8 col-8 mx-auto card myclass">
<div class="card-body">
<!-- info -->
</div>
</div>
</div>
{% endif %}
</div>
</body>
css
html, body {
height: 100%;
width: 100%;
}
.align-center {
align-content: center;
}
This is what it looks like right now. Notice how the border on the body is below the viewport.

You can wrap your card element inside a container(card-container) with position property set to relative. Give your card absolute positioning with top property set to 50%. Make sure your container has a height property specified.
Edit 2:
You can also use the flex-box feature of css to make your layout more reponsive. It will also resolve the issue that you are having on big screen. I have update the code inside the container and css classes applied to container section. Update your code accordingly and let me know.
.card-container {
display: flex;
flex-direction: row;
justify-content: center;
align-items: center;

You can do this by setting up your page height. Actually height:100vh fills the page completely. As you have the navbar, calc the height of it and subtract it from 100vh in this way height:calc(100vh - (56px)).
To set your card to the center of the page, you can use position:absolute and transform:translate(-50%,-50%) property. It will align your card to the vertical and horizontal center. I will be aligned to center in all the devices too.

There's no reason to use height:100%, calc() or extra CSS. Use the flexbox classes available in Bootstrap 4. Set a min height on the body (min-vh-100), flex direction column, and then flex-fill to allow the container to fill the remaining height. The vertical centering will then work as expected.
<body class="d-flex flex-column min-vh-100">

<div class="container-fluid d-flex flex-column flex-fill align-items-center justify-content-center">

On full width my page layout looks like this:
[navbar]
[1][2][3]
I was told in my previous post to use the "order-last order-md-first" but that doesn't really help me because when I resize the window I get something like this:
[navbar]
[2][3][1]
And the effect I'm looking for is:
[navbar]
[2][3]
....[1]
(the [1] div just under the [3])
Is it in any way achievable? Thanks in advance.

To achieve the effect you are looking for, you need besides the order classes also the offset classes.
But first the columns:
col-lg-3 -- col-lg-6 -- col-lg-3 in the code below means that the sidebar columns take up 3 units on larger screens and the center column 6 units (12 in total).
On smaller screens (smaller than lg), the center column gets 8 units (col-8) and the right column gets 4 units (col-4), adding up to a total of 12 once again.
That's why the left column must also have col-4 and needs an offset of 8 units on smaller screens in order to position it directly underneath the right column on smaller screens.
That's why we need the following set of order and offset classes for the left column:
order-last order-lg-first offset-8 offset-lg-0
order-last is the default order for the left column i.e. that's the order for the smallest screens (Bootstrap 4 is "mobile-first", so the smallest screens come first)
order-lg-first says: "From large (lg) screens and up you come first."
offset-8 determines the default offset i.e. for the smallest screens
offset-lg-0 means that from the large (lg) screen size and up there shall be no offset (zero offset).
