I have the below HTML and CSS. If one of the columns is hidden, I want to expand the other 3 columns. I don't think I can use col-md-3 for this scenario.
How can I do this?
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row">
<div class="col-md-3" *ngIf="hideCol1">
Column 1
</div>
<div class="col-md-3" *ngIf="hideCol2">
Column 2
</div>
<div class="col-md-3" *ngIf="hideCol3">
Column 3
</div>
<div class="col-md-3" *ngIf="hideCol4">
Column 4
</div>
</div>
You can use col-md (or just col) class to adjust columns automatically.
Thanks to flexbox, grid columns without a specified width will
automatically layout as equal width columns. For example, four
instances of .col-sm will each automatically be 25% wide from the
small breakpoint and up. See the auto-layout columns section for more
examples.

https://getbootstrap.com/docs/4.1/layout/grid/#auto-layout-columns
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row">
<div class="col-md" *ngIf="hideCol1">
Column 1
</div>
<div class="col-md" *ngIf="hideCol2">
Column 2
</div>
<div class="col-md" *ngIf="hideCol3">
Column 3
</div>
<div class="col-md" *ngIf="hideCol4">
Column 4
</div>
</div>
If you mean that when hiding a column via *ngIf you want the remaining columns to responsively resize themselves, you can just set each column's class to "col", instead of specifying the col size.

Using Bootstrap 3.3.7, I have this markup:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<div class="container-fluid">
<div class="row">
<div class="col-md-6">
Col 1 Main text goes here
</div>
<div class="col-md-3">
Col 2 List of links to other pages here
</div>
<div class="col-md-3">
Col 3 Sidebar text
</div>
</div>
</div>
As I reduce browser window size, I would expect Cols 2 and 3 to wrap below Col 1 but display alongside each other initially.
Instead, all three columns are stacked vertically after first break. How do I alter this behavior?
With bootstrap the -md- denotes "medium". So as that is the only size you've set, bootstrap defaults will be used for when it's small. You can add different column numbers specifically for when the screen gets smaller using "col-sm" alongside the "col-md" like this:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<div class="container-fluid">
<div class="row">
<div class="col-md-6">
Col 1 Main text goes here
</div>
<div class="col-md-3 col-sm-3">
Col 2 List of links to other pages here
</div>
<div class="col-md-3 col-sm-3">
Col 3 Sidebar text
</div>
</div>
</div>
You can also hard-code columns by removing the "-md" section.

I have a basic Bootstrap 4 grid like this one:

<div class="col">

Columns are correctly stretching and filling out the row width, but on some viewports last column is sent to next row (since it doesn't fit) and somehow stretching too much (and taking full width of row).
How can I prevent this from happening?
Use flex-nowrap on the row...
<div class="container">
<div class="row flex-nowrap">
<div class="col">
some content
</div>
<div class="col">
some content
</div>
<div class="col">

<div class="col">

</div>
<div class="col">

<div class="col">

Columns inside a row can be styled using bootstrap class col-xs-* so that all your columns fit into the same row instead of going to the next row.
For example,
<div class="container">
<div class="row">
<div class="col-xs-4">
</div>
<div class="col-xs-4">
</div>
<div class="col-xs-4">
</div>
</div>
</div>
You can use the bootstrap breakpoints in col by add extra few classes such as:
col-lg-x where x is a given number in the 12 grid system provided by bootstrap, for example you want all seven column to be on one row on large screens, and it should breakdown to two on each row on mobile screen, you simply add a class col-xs-x where x is a given number from 1 to 12, by giving it col-xs-6 col-md-3 col-lg-1 where xs represents small and extra small devices, md represents medium devices and lg represents large screen devices.
You're simply translating that on xs devices it should be two on a row and on md devices it should be four on a row and lg devices should be that seven column on a row.

i am trying to set up three columns but they are laid out directly beside each other, no gutters.
seemingly, i can also put an endless amount of columns across the row and the "4" specification will not stop at 3 columns.
<div class="container-fluid">
<div class="row">
<div class="col-xs-4">
<p>Test<br>Test description</p>
</div>
<div class="col-xs-4">
<p>Test<br>Test description</p>
</div>
</div>
</div>
In head, try this
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
That is cdn to bootstrap version 3
Grid in bootstrap is 12. if you need for 4 row. you can add .row again in another div you can see documentation here
I am trying to learn Bootstrap grid more. I am trying to get two columns in two rows in the middle of my page.
So it should look like this:
Here is what I got so far:
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<div class="container">
<div class="row">
<div class="col-xs-6 col-sm-6">
<div id="text1">
<label>Text 1</label>
</div>
<div id="text2">
<label>Text 2</label>
</div>
</div>
<div class="col-xs-6 col-sm-6">
<div id="text3">
<label>Text 3</label>
</div>
<div id="text4">
<label>Text 4</label>
</div>
</div>
</div>
</div>
But my elements are not in place where I want them.
Here is the solution in a fiddle: Solution 1
Now for the explanation of the problem:
First you need to set specific columns. Keep in mind that Bootstrap has a grid of 12. So your maximum can be 12 at all time. However, you don't need to have the columns fill the entire grid.
You can use something called offset which allows you to put empty space in your elements. Having the class class="col-md-5 col-lg-5 col-sm-5 offset-1" gives you a column with a value of 5 so you can actually position 2 columns and have space on the side.
I would suggest to go through the Bootstrap grid and play around in order to get a familiar feeling on how to manipulate it.
The style sheet margin-left:25px; margin-top:25px; gives you the space on the top and on the side of the columns themselves.
Im fairly new to bootstrap and the concept of responsive design.
I was reading over the bootstrap docs and following some tutorials on w3schools. All mentions col- must = 12 in a single row class. They also mention you can combine different col classes and sizes example <div class="col-md-3 col-xs-6">
What I am not getting is when should you break the viewport with the </row> class when you combine different col sizes ?
Consider the following, where I want a mobile device to display 2 rows and 2 columns and on desktop a single column with 4 rows
<div class="container">
<div class="row">
<div class="col-md-3 col-xs-6">
</div>
<div class="col-md-3 col-xs-6">
</div>
<div class="col-md-3 col-xs-6">
</div>
<div class="col-md-3 col-xs-6">
</div>
</div><!--/row -->
</div><!--/container -->
Considering all columns inside rows must = 12, the row class would need to be closed on different points for mobile and desktop...?
How would I tackle the above problem, hope the question makes sense.
Thank you
Your code is correct and doesn't need more .rows. The W3schools tutorial is misleading, and it's wrong to say ".col-*-* should always add up to 12 for each row".
It's ok to have more (or less) than 12 column units in a Bootstrap .row. It's known as column wrapping, and will simply make the extra columns wrap to the next line...
From the Bootstrap docs:
"If more than 12 columns are placed within a single row, each group of
extra columns will, as one unit, wrap onto a new line"
That's why there are examples in the Bootstrap docs that demonstrate using more than 12 columns in a single .row. When using column wrapping you do need to be aware of responsive resets (known as "clearfix") if the columns vary in height.
There are many responsive scenarios (like your example) where it's necessary to have column units exceeding 12 in a single .row element. It's a common misconception that column units must be 12 or less in a single .row.

Just change the "col-md-3" class to "col-md-12" in all divs to show 4 rows and single column on desktop and two rows and two columns on mobile.
<div class="container">
<div class="row">
<div class="col-md-12 col-xs-6">
</div>
<div class="col-md-12 col-xs-6">

The .row class is not required inside a .container, but it is a good idea to include it anyways when you start incase you want multiple rows later on.
All that .row really does is make sure that all of the divs inside of it appear on their own line, separated from the previous and the following .rows
It's just proper nesting..the problem that you have mentioned in your question can be solved in the following way--
As you can see a mobile device will display 2 rows and 2 columns and on desktop a single column will have 4 rows--
Although it can be achieved using many other div nesting methods, I have shown only one such configuration to achieve your desired layout.
