Bootstrap’s grid system uses a series of containers, rows, and columns to layout and align content. It’s built with flexbox and is fully responsive. Below is an example and an in-depth look at how the grid comes together.

Only Important Code


<div class="container-fluid">
  <h1>Hello World!</h1>
  <p>Three equal width columns! Try to add a new div with class="col" inside the row class - this will create four equal-width columns.</p>
  <div class="row">
    <div class="col" style="background-color:lavender;">.col</div>
    <div class="col" style="background-color:orange;">.col</div>
    <div class="col" style="background-color:lavender;">.col</div>
  </div>
</div>

  <p>Resize the browser window to see the effect.</p>
  <p>The columns will automatically stack on top of each other when the screen is less than 576px wide.</p>
  <div class="row">
    <div class="col-sm-4" style="background-color:lavender;">.col-sm-4</div>
    <div class="col-sm-8" style="background-color:lavenderblush;">.col-sm-8</div>
