Is there a way to scale up form elements of a form with a Bootstrap 4 so they would stretch to the whole row width?
The arrangement I have now looks horrible: http://prntscr.com/id6pfm
HTML:
<div class="jumbotron vertical-center">
<div class="container-fluid">
<div class="row align-items-center justify-content-center">
<div class="col-xs-12 col-sm-6 col-md-4 col-lg-3">
<form class="form-group" method='POST' action='reset_password.php' enctype=utf-8 accept-charset=utf-8>
<input class="form-block" type='password' name='password' placeholder="New password" size='20'>
<input class="form-block" type='password' name='password_confirm' placeholder="Confirm new password" size='20'>
<input class="form-block" type='submit' value='Reset password'></input>
</form>
</div>
</div>
</div>
</div>
CSS:
.vertical-center {
min-height: 100%;
min-height: 100vh;
display: flex;
align-items: center;
}
You need to have the following meta tag in the head of the document:
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
And make sure you remove the unnecessary custom css. Bootstrap 4 is flexbox-based by default.
Here's a starter template you can use for all your documents:

In my VS Code editor when I code for a responsive web sites (for example - the below code), the output web page should be responsive for long/small/medium screen size(expectation) but the output web page is not as I have expected although I have included the Bootstrap CDN links in the head tag.

I tried to make an responsive website using HTML, CSS, and Bootstrap and the code is above. I was expecting from it to be responsive for long/small/medium screen size but it is not responsive.
Use this code

I'm looking to build a bootstrap v4 grid with 3 cols, but some of the content within the col needs to have a min-width. Therefore they should have a horizontal scroll (overflow-x) but there seems to be some overlap and the scrollbar and content are appearing outside the col.
Essentially the div of Col content 1 (orange border) should all fit within the Col container 1 (black border)

Thanks
Is this what you were going for? The code is pretty much self-explanatory. I did place the new css in a class .wrapScroll as opposed to inline.
You mention the need for a min-width but I did not understand that need so did not use min-width.
.wrapScroll {
white-space: nowrap;
overflow-x: auto;
border: 1px solid orange;
}

I have limited experience with Bootstrap 4 but am not sure why my page is acting like this. I have these 2 rows, one of which I want for the title to be above the container with white background. I am trying to make 2 columns, one for a sidebar and one for the content on the right however when I use columns they only stack which can be seen here - http://michaelfroseth.com/clients/notebook-html/subpage.html
I have no idea why? They seem to operate fine outside of the row, but am I not supposed to be using a new row? Any documentation or point in the right direction would be much appreciated!

You should use row inside the container, not as a wrapper.

I have an issue with a menu im trying to create. I kinda got the old bootstrap, but this whole flex-thingy is confusing for me. So, i want to have a 80px dark vertical side menu and the rest of the screen should be a "working area". My problem is that the items in the side menu does not have full width (see the borders below) and I cant seem to figure out why not. I am guessing right now, that it has something to do with the flexbox - an item taking up only the space it needs. Im have copied the code from bootstrap 4 website and modified a bit. But that last bit, where I can get full width on the items - that one I am missing.

It's not related to your .nav-item, it's because .nav doesn't take full width of its parent. Try updating bootstrap to 4.1 and insert .flex-fill to your nav:
.nav-item{
color:#FEFEFE!important;
border-bottom:1px solid #666;
}

In case you don't want to update bootstrap, you can simply add flex: 1 1 auto to .nav style:
.nav-item{
color:#FEFEFE!important;
border-bottom:1px solid #666;

Here's what I see:
Note: According to this video it should work though https://teamtreehouse.com/library/bootstrap-4-basics/getting-to-know-bootstrap-4/enhancing-the-page
You are using the alpha 4 of bootstrap(js), use bootstrap 3.x.
Also you have an extra </div> in the code.
This works:
<!--http://v4-alpha.getbootstrap.com/getting-started/introduction/-->
<!DOCTYPE html>
<html lang="en">
<head>
<!-- Required meta tags always come first -->
<meta charset="utf-8">
<meta http-equiv="x-ua-compatible" content="ie=edge">

</head>
<body class="bg-info">
<div class="container text-xs-center">

What do you mean by doesn't work for the whole body? Try to add this CSS property to your custom CSS:
.bg-info {background: #5bc0de!important;
}
