Grid do not have margins in bootstrap

Question

I have a simple page with bootstrap, and I want to create a grid which is one-line or two-line on smaller screend, but I always get something incorrect: with show-grid

Answer 1

Rules to Bootstrap:

Use rows and columns alternating
Rows have a negative margin to ensure that the columns respect the containers width.

container
|   row
|   |   column
|   |   |   row
|   |   |   |   column
|   |   |   |   column
|   |   |   row
|   |   |   |   column
|   |   |   |   column
|   |   column

Always include col-xs-* on columns
This is to prevent floating issues. If your column is supposed to be 12 wide anyways dont just ignore the col-xs-12

Mobile first
Start with the smallest screen size. Go from xs < sm < md < lg and you should be all good!

Small columns serve as larger columns
A sm column does serve as a md column as well, if not specified otherwise.

  

      This is the same
  

  

      as this one

And at last: Do not style rows and columns!
Feel free to add classes to modify them, but do not override them in any way!

Bad example:

.row {
  border: 5px solid pink;
  margin: 0 10px;
}


  

    This is a no-go!
  

Good example

.pink-bordered {
  border: 5px solid pink;
  margin: 0 10px;
}


  

    Totally fine
