recently, I have downloaded videos from youtube on learning bootstrap 4 for responsive web design and everything works fine for me when I use
<div class="col-md-6> the md class for the medium screen and lg class for large screen works fine but xl class for the extra small devices and sm class for small devices no matter how I zoom the page and I have downloaded responsive website test extension for chrome but still nothing. this is the code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Learn BOOTSTRAP CSS</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="css/bootstrap.min.css">
<script src="js/jquery-3.2.1.min.js"></script>
</head>
<body>
<div class="container">
<div class="row">
# this is the parent class and it should take the entire page width
<div class="col-lg-6 col-md-6 col-sm-12 bg-primary">
<p>this is the primary color</p>
<div class="row">
# and this is the child class and it should take 6 col of it parent class
<div class="col-lg-6 col-md-6 col-sm-6 bg-success">
<p>this is the success color</p>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
look like I didn't work because I was using Bootstrap 4, when I used bootstrap
3 the code works fine for me

I'm new to bootstrap, trying to align 2 divs vertical on responsive mode, but no luck so far.

On normal desktop mode, the divs are vertically aligned. But once I go to mobile mode, the second div is sitting below the first div. How can I make the 2nd div to sit next to the first div vertically?
Most of the boostrap over mobile devices tend to make things one below another because that is pretty much what bootstrap does in CSS/Div elements on mobile.
There are some solutions over it, but I see in your elements before
<div class="col-xs-12 col-sm-1" ><i class="material-icons">cloud</i>
that you don't use the triple rule.
Using bootstrap col- elements should be always into container and row like this:
<div class="container"> <!-- Or container-fluid -->
<div class="row">
<div class="col-xs-12 col-sm-1">
most inner div
<div/>
<div/>
<div/>
A little harder as solution is to copy the whole Bootstrap grid css file into a new file you make and you modify the things you need the most, like the .col-lg xs or the flex and the max width
Last but not least, go check the #media element over here:
https://www.w3schools.com/css/css_rwd_intro.asp
This could help you understand the most of what I said before about auto-resizing over mobile devices and css elements
<!--Try this one, It's simple and responsive in all widths and are aligned vertically can also do this using css flex box but little bit lengthy.-->

You wrote
<div class="col-xs-12 col-sm-1" >
The col-xs-12 means, that on small screens, this element should fill the complete container. Use
<div class="col-xs-6 col-sm-1" >
for both containers, or one col-xs-1 and the other col-xs-11.
There are 12 columns in bootstrap and you decide, how they are filled
The objective it's to hide the red column on mobile and show it on higher resolutions but it just does not hide. Can somebody tell me what it's wrong with my code?, I pasted it in fiddle and works perfect but I take the same to my project and it does not work... What am I doing wrong? I'm using bootstrap 4.2.1

Chrome test(also proved on real phone with the same result)
Simply add
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Into your <head>
A viewport element gives the browser instructions on how to control the page's dimensions and scaling. The width=device-width part sets the width of the page to follow the screen-width of the device (which will vary depending on the device). The initial-scale=1.0 part sets the initial zoom level when the page is first loaded by the browser.
(Source w3schools)
Try this code
<div className="row">
<div className="col-md-12 bg-danger d-none d-lg-block" style="height: 100vh">
</div>
<div className="col-12 col-md-12 bg-success d-lg-none" style="height: 100vh">
</div>

Responsive website zoomed out to full width on mobile

Can you say why do this code is not adapt to different mobile devices? I am HTML beginner and can not figure it out. I'm using Bootstrap 4 framework.

You use classes such as col-md-6 and col-md-3, these are for medium sized screens., for mobiles, you need classes such as col-6 and col-3. See here for examples and definitions
"Can you say why do this code is not adapt to different mobile
devices?"
The meta tag is wrong. It should be:
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
The page will never be responsive without the correct meta tag. Please read the documentation...
"To ensure proper rendering and touch zooming for all devices, add the
responsive viewport meta tag to your <head>."
Also see:
Simple Bootstrap page is not responsive on the iPhone
Responsive website zoomed out to full width on mobile
For design to be responsive for mobile devices, use bootstrap classes like col-xs-3, col-xs-6. "col-xs-*" is used to target mobile devices having width greater than 230 and less than 768. Also use #media screen {} to target specific style to specific width mobile device.
I seem to be having some strange issues with IE 11. Nothing is contained like it is in Chrome and everything is overflowing like crazy.Everything looks fine in Chrome and Safari and any mobile browser, but IE11 is struggling.

And here is a snippet of one of my routes:
<div class="section-b">
<div class="container-fluid">
<div class="row vertical-align">
<div class="col-lg-3 col-lg-push-8 col-sm-12"><img alt="Alaska"
class="img-responsive intro-img" src=
"images/introduction_a.jpg"></div>
<div class="col-lg-6 col-lg-offset-1 col-lg-pull-3 col-sm-12">
<div class="clearfix"></div>
<p class="lead">Some text will go here</p>
</div>
</div>
</div>
</div>
In the screenshot below the white area is the text-area and that's an img-responsive, the default width of the page is meant to be the same size as the last image as it's set to 100%. Any suggestions? I'm hoping it's something really simple.
I'm using Bootstrap 3.0 panels and trying to figure out why a page is not responsive on mobile devices. It displays properly on a desktop browser, but doesn't view optimized on mobile devices.
The panel examples on the Bootstrap site do indeed display optimized on mobile.
Am I missing something?

Looks like you're missing a viewport tag in the head of your HTML. Docs
Like this:
<meta content='maximum-scale=1.0, initial-scale=1.0, width=device-width' name='viewport'>
Except it could be argued that disabling zoom is a bad idea if your text is too small to read, so take care to test it on a variety of devices with different users in mind.
