8 – CDN provider jsDelivr does not work with bootstrap for drupal

I'm trying to create a Drupal theme with bootstrap. However, my boostrap is not loaded due to jsDelivr malfunctions (I think).



PS: Does anyone know of any good Drupal guides / books? Because I have to make a drupal website, and my "course" (for which I have to do the site) does not explain things well.

Request page confirmation with Modal Bootstrap

Is it possible to request a page leave confirmation (to avoid any data loss) on before unloading event with a modal Bootstrap?

8 – The best solution for a mega-menu multi-columns in combination with bootstrap 4

I use Bootstrap 4 (not the Bootstrap theme but a custom configuration) for my custom Drupal 8 theme. I have a main menu with taxonomy categories and links. I need to divide these categories and its links (children) into several columns (mega-menu).

What is the best way to do it, so that it also works with, or that I can easily integrate it into Bootstrap Navbar and Navbar toggler?

Is it still useful to use Bootstrap and jQuery?

I think the question itself is quite simple, but I think it's best to explain my situation a little bit.
I do not work professionally on the front end, either in reality or with programming. My hobby is programming without big intentions. The backend interests me, but since it's just me, I also have to expose things, so let's say that the bootstrap has put an end to a lot of my suffering.
I love learning this, but I would like to invest my time in something that I could share in the future, in a conversation, and so on. As good as it is, it would not be very interesting to learn something about death.

* About jQuery, I used very little, so I prefer not to comment.
* All about CSS Grid, I know how to use the basics, especially when you have to dynamically insert widgets on the screen.
* I know that the bootstrap is still used and I also have some idea that I've probably said bullshit, do not throw me too many stones. I know that I am ignorant on the subject, so I asked for help.

Otherwise, thank you all or not (I do not know if I will take a vacuum). See you later.

twitter bootstrap – 4 bucket elements do not respond

enter the description of the image hereI have 4 bucket elements coded with bootstrap and a php loop in wordpress. I want the 4 bucket elements to appear in a row for the desktop and be reduced to columns on mobile. This is the only way for me to make them appear in a row on the desk. However, I can not reduce them using multimedia queries, such as flex-direction: column.


'posts_per_page' => '4',


$blogposts = new WP_Query($args);
