How to set the button alignment in Bootstrap ?

19 Jun, 2019
Bootstrap buttons are no different from any other DOM elements of an HTML document. Aligning them is more likely the same as aligning paragraphs, divs and sections. Here are some of the scenarios that one can encounter.
.text-left
.text-center
.text-right
Syntax:
class="text-left"|"text-center"|"text-right"

Note: You can also use HTML5 <center> tag to align buttons to the center.
Example:
<!DOCTYPE html><html>  <head>    <meta charset="utf-8">    <meta name="viewport"     content="width=device-width, initial-scale=1, shrink-to-fit=no">      <link rel="stylesheet"href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" />      <title>Aligning Buttons</title></head>  <body>    <h1 style="color:green;text-align:center;">GeeksforGeeks</h1>    <div class="container">        <div class="text-left">            <button type="button" >Button 1</button>            <button type="button" >Button 2</button>        </div>          <div class="text-center">            <button type="button" >Button 1</button>            <button type="button" >Button 2</button>        </div>          <div class="text-right">            <button type="button" >Button 1</button>            <button type="button" >Button 2</button>        </div>          <center>            <button type="button" >Button 1</button>            <button type="button" >Button 2</button>        </center>    </div>      <script src="https://code.jquery.com/jquery-3.2.1.slim.min.js">    </script>    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js">    </script></body>  </html>
Output:
.d-flex .flex-row
.d-flex .flex-column
The following pattern can be achieved by choosing either one of them.Example:
<!DOCTYPE html><html>  <head>    <meta charset="utf-8">    <meta name="viewport"      content="width=device-width, initial-scale=1, shrink-to-fit=no">      <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" />      <title>Aligning Buttons</title>      <style type="text/css">        html,        body {            height: 200px;        }    </style></head>  <body>    <h1 style="color:green;text-align:center;">GeeksforGeeks</h1>    <div class="container h-100">        <div class="d-flex h-100">            <div class="align-self-start mr-auto">                <button type="button" class="btn btn-danger">                  Click Me!                </button>            </div>            <div class="align-self-center mx-auto">                <button type="button" class="btn btn-primary">                  Click Me!                </button>            </div>            <div class="align-self-end ml-auto">                <button type="button" class="btn btn-success">                  Click Me!                </button>            </div>        </div>    </div>      <script src="https://code.jquery.com/jquery-3.2.1.slim.min.js">    </script>    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js">    </script></body>  </html>
Output:
This is the most used method present online. In this case, the parent div is assigned a position ‘relative’ while the child divs are assigned position ‘absolute’.Elements inside ‘absolute’ divs can be aligned in whatever way you want. Consider the following example. It shows all possible alignments a DOM element, in this case, buttons can have.
Example:
<!DOCTYPE html><html>  <head>    <meta name="viewport"    ontent="width=device-width, initial-scale=1, shrink-to-fit=no">      <link rel="stylesheet"href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" />      <title>Aligning Buttons</title>      <style type="text/css">        html,        body {            height: 300px;        }                  .top-left {            top: 0;            left: 0;        }                  .top-center {            top: 0;            left: 50%;            transform: translateX(-50%);        }                  .top-right {            top: 0;            right: 0;        }                  .mid-left {            top: 50%;            left: 0;            transform: translateY(-50%);        }                  .mid-center {            top: 50%;            left: 50%;            transform: translateX(-50%) translateY(-50%);        }                  .mid-right {            top: 50%;            right: 0;            transform: translateY(-50%);        }                  .bottom-left {            bottom: 0;            left: 0;        }                  .bottom-center {            bottom: 0;            left: 50%;            transform: translateX(-50%);        }                  .bottom-right {            bottom: 0;            right: 0;        }    </style></head>  <body>    <h1 style="color:green; text-align:center;">GeeksforGeeks</h1>    <div class="container h-100">        <div class="position-relative h-100">            <div class="position-absolute top-left">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>            <div class="position-absolute top-center">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>            <div class="position-absolute top-right">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>              <div class="position-absolute mid-left">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>            <div class="position-absolute mid-center">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>            <div class="position-absolute mid-right">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>              <div class="position-absolute bottom-left">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>            <div class="position-absolute bottom-center">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>            <div class="position-absolute bottom-right">                <button type="button" class="btn btn-primary">Click Me!</button>            </div>        </div>    </div>      <script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js">    </script></body>  </html>
