Do you need bootstrap as a layout tool?

Question

css

Hello!
I am a novice coder (I train on relatively simple landing pages + building on gulp + sass).
The other day they sent a test task (for the position of HTML layout designer / junior frontend developer). What surprised me was the TOR (I give an excerpt from the most ambiguous points of the TOR):
1. Design the landing page using the Bootstrap 3.0 grid
2. Project builder - webpack
3. Use the BEM naming styles
4. Also use the Sass preprocessor
...
Of course I I understand that the employer immediately decided to cram everything into one task BUT:
1. Is there any point in Bootstrap if there is flexbox and CSS Grid?
2. Why dance with a tambourine to redefine styles (BEM)? How do BEM and Bootstrap fit together?
Using flex, I realized how convenient it is. I opened Bootstrap, started to study... and I don't understand if there is any sense in all its sheets with documentation?? How in general is Bootstrap in demand in the industry)?
The main question: Bootstrap - is it convenient, high-quality and fast, or are there still serious drawbacks?
The purpose of my question is to get the opinion of the community, not to find an excuse not to learn Bootstrap.
Thank you.

1. Yes, usually in such offices they do everything on it, so that later they don’t bother much with support and do it faster.
2. No need to override, BEM and Bootstrap can live together. These questions have already been asked, you can search. For example: https://github.com/bem-site/bem-forum-content-en/i...
Bootstrap has its drawbacks, like any tool. At work, most often you don’t have to choose what exactly to work with, if there are already established principles of work. You need to be able to adapt and delve into the new, and into the “sheet of documentation”.

You are talking about a few different things.
Flexbox is just a way of layout. And Bootstrap is a tool that will allow you to make a full-fledged website. The bootstrap has a slider, and a carousel, and buttons, and navigation bars, and accordions, and pagination, and everything you might need.
If you use flexbox, you will be able to make layout. Yes. And when you want to put a slider on the site, then you will go looking for libraries that allow you to make a slider. You will study these libraries. How to connect them, how to set them up, etc. etc. Then you will need to make a drop down menu. You will go looking for libraries to create such a menu. Then something else, and so every time.
As a result, you will have to study a whole bunch of all sorts of libraries. Connect a bunch of libraries to the site. Familiarize yourself with their settings.
And if you open a Bootstrap site instead, then you connect this Bootstrap to the site once, and you can do everything you need. Everything is lined up there. Everything is in Russian. All with examples.
Need a slider? open the bootstrap page with sliders, copy the code, paste it on your site, and you're done. Need pagination? or accordion? You copy the code to your site and that's it. Also with the menu, with buttons, etc.
There are also modal windows, and spinners, and tooltips, etc.
Those. You are just learning Bootstrap and you don't need any libraries anymore.
Bootstrap is not only a grid. Not only layout. It's also a lot of functionality.
It's not just css , it's also js .
And besides, you immediately get an adaptive layout.
Of course, if you need some more complex slider, then you still need to look for other libraries, but this, as they say, there is no limit to learning and learning ...
Bottom line. Better study Bootstrap. Save a lot of time and get everything in one bottle at once.

Answer 3

In any case, very suitable for prototyping

Answer 4

So you only need to use the grid.
It will be in any way in 99.99% of projects. And in bootstrap the most convenient in my opinion.
Flex is flexible, but there are a lot of bugs with it. When there are 100,500 blocks in a project, you get tired of catching them, and the grid works everywhere.

Answer 5

Use only a grid from bs. 4th Bootstrap is also on flex
Requirements are not written by you, if you manage to persuade the customer how much better it will be for him - try it.
There is a possibility that he has previous projects on the third BS and he does not want to change anything, which is quite understandable and some rookie, without arguments, wants to say that it is more convenient for him. pfft

Answer 6

From the bootstrap I use only the grid, from version 4.
