how to use scrollspy in bootstrap4? - html

I am new to html/bootstrap/css.
I'm trying to make scrollspy in a list on a website page that I'm currently working on (essentially, I'm only modifying HTML produced by R postcards package).
Here is my HTML code. This file uses bootstrap 3.4.1, I can't replicate the expected behavior with bootstrap 4. When I do use <script> with a newer version of Bootstrap (say 4.5.0) the buttons/list items (li)/links do not seem to be active anymore as I scroll through the page.
I'm not sure why this code does not run as expected using newer versions of bootstrap.

First of all, to add scroll spy to your site you need to add in your body tag as following: <body> data-spy="scroll" data-target="[class of the target]" data-offset="[can be any value, depending on your likings]">. You also need a place where the links should be updated, a navbar for example, (noted in the code above with [class of the target]). In your navbar, there should be <a> tags that link to the section id, for example My link.
You can also add custom styling to the links when they are active like here: a:active { //the active style }.

Ellipsis in card header

I am using Bootstrap 4 and I want to create a card header which consists of 3 parts.
Left part displays author.
Middle part displays preview of the content.
Right part displays the date.
I want middle part to cut off with ellipsis when it reaches the end of available space. Middle part should, therefore, span from left to right part with margin ml-5 and mr-5. If content is longer than available width, it should display ellipsis. All 3 parts must be in one line.
Here is my code so far:
<div class="container">
<div class="row">
<div class="col-8">
<div class="card">
<div class="card-header">
<span class="float-left">
John Seed
</span>
<span class="ml-5 mr-5 text-muted" style="text-overflow: ellipsis; white-space: nowrap; overflow: hidden; display: inline-block;">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas finibus vitae magna id aliquam. Phasellus luctus ut ligula eu dignissim. Praesent sodales, nisi quis sodales euismod, enim ante suscipit ex, in cursus est metus nec sem. Pellentesque pharetra lobortis sem in tempus. Morbi turpis leo, rhoncus in eleifend id, pellentesque nec metus. Maecenas commodo scelerisque pellentesque. Suspendisse rhoncus at augue at egestas. Ut in erat ut justo tincidunt suscipit ac sit amet urna. Curabitur lacinia diam sit amet velit gravida hendrerit. Duis a orci quis enim iaculis ultrices. Duis finibus lorem et ipsum fringilla, feugiat ullamcorper turpis lacinia. Nunc vulputate in tortor ac lacinia. Pellentesque nec nibh ut est consequat condimentum vel ut velit. Phasellus elementum vel dui vitae lacinia. Nulla et placerat dui, a laoreet lectus.
</span>
<span class="float-right">
10-Mar-2020
</span>
</div>
<div class="card-body">
This is card content.
</div>
</div>
</div>
</div>
</div>
Preview:
If I add, for example, width: 300px to the middle part, it displays ellipsis correctly. However, width is fixed which is not something that I would like.

You can just add a d-flex to the parent container.
Read up on d-flex here
I'd also recommend to remove the float since it isn't needed here. You always want to avoid float whenever possible and use flexbox instead. Float can destroy your layout and has to be cleared.
Edit: To prevent the left and right span to break into a new line you should add the .text-nowrap class from Bootstrap Utility.

How can I allow the content to be appear beside the image and under the image also after the image ends?

I am working on my blog posts in wordpress. What I want is the content of blog should be beside the post thumbnail and when the image ends the content should automatically cover the rest of the area I mean it should start under the image form the left?
Here is the output image:
I this picture I have used bootstrap's grids system which is 6 columns to thumbnail and 6 columns to the content which is ok, but I want the content to automatically fill the rest of the space under the image? How can I achieve it using CSS or Bootstrap?

Since you are using bootstrap. This is impossible to do with its current setup.
Setting it to 2 columns at 50% with the image in one and all text/content in the other will display just like you have it.
You could need to set it to a col or col-12 and add the image/text in the same area.
Think old school WordPress content editor with image alignment.
Here is an example you could mimic to get the text to wrap. The jsfiddle is a working example.
<div class="container">
<div class="row">
<div class="col">
1 of 2
</div>
<div class="col">
2 of 2
</div>
</div>
<div class="row">
<div class="col">
<img src="https://via.placeholder.com/150">
Text goes here
</div>
</div>
</div>

You can do this -
HTML
<div class="container">
<div class="row">
<div class="col">
<img class= "pull-left" style="margin: 0px 10px 0px 0px;" src="https://via.placeholder.com/150" width = "150">

I was on the impression that .sticky-top class would sort out the situation for the top menu but cant figure out exactly what is causing this issue. How can I make sure that in below simple page both top menu bar and footer are sticky?

For the sticky header, you add the class to header instead of nav as below:
<!doctype html>
<html lang="en">

There is no sticky-bottom class but there are some tutorials to set a sticky footer, like this

Another option can be just add position: sticky; bottom: 0 to <footer> tag

Sticky DIV stays at the bottom on scroll but does not overlap footer

I have a page with 5 divs and a footer. I want for one DIV to be stickied at the bottom of a screen while a user scrolls. I had half achieved this with fixed bottom but then it would overlap the footer. Another thing I tried was to have the footer with a higher z-index but I'd prefer the sticky DIV to not go behind the footer. Eg. If I scroll down and my sticky div is at the bottom of the screen and I reach the footer, it will dock touching the top of the footer until I scroll back up in which case it would follow me back up the page but always stay at the bottom of the screen

CSS Flexbox affecting Bootstrap 3 layout

I'm trying to create the layout below in Bootstrap 3.
I can achieve layout shown under 'sm', and with flexbox I want to swap div 1 and 2 for xs screens. The problem is when I make the containing div a flexbox, it pushes down div 3 on the sm layout, so that it is underneath div 2.

And the CSS
.flex-container {
display: flex;
flex-wrap: wrap;
}
If I remove 'flex-container' from my containing div class, it then goes back to being as I would like it to be in the picture above. Is there a way to solve this so that I can have my correct layout for sm, even with flexbox?
I originally tried to solve this using Masonry, but a Stackoverflow user suggested flexbox instead (which I'd not used before) so hopefully I'm on the right track. If not.. any pointers would be grand!
Here is a JS Fiddle with the media query and flexbox ordering included.

Use the Boostrap grid columns like this..
<div class="container-fluid">
<div class="row">
<div class="col-xs-12 col-md-4 pull-right">
<div class="well">
<h4>1</h4>
</div>
</div>
<div class="col-xs-12 col-md-8">
<div class="well tall">
<h4>2</h4>
</div>
</div>
<div class="col-xs-12 col-md-4 pull-right">
<div class="well">
3
</div>
</div>
</div>
