Bootstrap 4 | Flex
The flex classes are used to control the layout of flexbox components.
Example:
HTML
<!DOCTYPE html><html lang="en"><head> <title>Flex</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href= <script src= </script> <script src= </script> <script src= </script></head><body> <div class="container mt-3"> <h1 style="color:green; text-align:center;"> GeeksforGeeks </h1> <h2 style="text-align:center;">Flex</h2> <div class="d-flex bg-success p-3 text-white"> <div class="p-2 bg-primary">Flexbox 1</div> <div class="p-2 bg-secondary ">Flexbox 2</div> <div class="p-2 bg-info">Flexbox 3</div> </div> </div></body></html> |
Output:
Inline Flexbox Container: The .d-inline-flex class is used to create an inline flexbox container.
Example:
HTML
<!DOCTYPE html><html lang="en"><head> <title>Flex</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href= <script src= </script> <script src= </script> <script src= </script></head><body> <div class="container mt-3"> <h1 style="color:green; text-align:center;"> GeeksforGeeks </h1> <h2 style="text-align:center;">Inline Flexbox</h2> <div class="d-inline-flex bg-success p-3 text-white"> <div class="p-2 bg-primary">Flexbox 1</div> <div class="p-2 bg-secondary ">Flexbox 2</div> <div class="p-2 bg-info">Flexbox 3</div> </div> </div></body></html> |

Example:
HTML
<!DOCTYPE html><html lang="en"><head> <title>Flex</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href= <script src= </script> <script src= </script> <script src= </script></head><body> <div class="container mt-3"> <h1 style="color:green; text-align:center;"> GeeksforGeeks </h1> <h2 style="text-align:center;">Horizontal Flexbox</h2> <h3>flex-row class</h3> <div class="d-flex flex-row bg-success mb-3 text-white"> <div class="p-2 bg-primary">Flexbox 1</div> <div class="p-2 bg-secondary ">Flexbox 2</div> <div class="p-2 bg-info">Flexbox 3</div> </div> <br> <h3>flex-row-reverse class</h3> <div class="d-flex flex-row-reverse bg-success mb-3 text-white"> <div class="p-2 bg-primary">Flexbox 1</div> <div class="p-2 bg-secondary ">Flexbox 2</div> <div class="p-2 bg-info">Flexbox 3</div> </div> </div></body></html> |
