How to set vertical alignment in Bootstrap ?
Vertical Alignment changes the alignment of elements vertically with the help of vertical-alignment utilities. The vertical-align utilities only affect inline(Present in one Line), inline-block(Present as blocks in one line), inline-table, and table cell(Elements in a cell of a table) elements. Vertical Alignment of div is one of the most basic requirements of a responsive web page. This can be achieved through CSS but the Bootstrap library has some classes specifically built for this purpose. In this article, we will learn the available classes & methods used for vertical-align in Bootstrap. Please refer to Vertical alignment in Bootstrap with Examples for other vertical-align classes.
Here, we will discuss 2 built-in classes:
- Using class align-items-center
- Using class d-flex with class align-items-center
Let’s understand both the classes through examples.
Method 1: Using class align-items-center
In Bootstrap 5, if we want to vertically align an <div> element in the center, we can do this by applying the class align-items-center on the containing element of that div.
Example:
HTML
<!DOCTYPE html><html lang="en"> <head> <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"> <div class="row align-items-center bg-success text-light" style="min-height: 100vh"> <div class="col-md-12"> <h1>GeeksforGeeks</h1> </div> </div> </div> </body></html> |
Output:
Method 2: Using class d-flex with class align-items-center
In Bootstrap 5, if we want to vertically align an <div> element in the middle of a containing element, we can do this by applying the class align-items-center and d-flex on the containing element of that div. Here, the d-flex class has the same effect as that of the display: flex; property in CSS.
Example:
HTML
<!DOCTYPE html><html lang="en"> <head> <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="d-flex align-items-center" style="min-height: 100vh"> <div class="box w-100 text-success"> <h1>GeeksforGeeks</h1> </div> </div> </body></html> |
