Input Groups in Bootstrap with Examples
Last Updated :
03 Aug, 2023
Input Groups in Bootstrap are used to extend the default form controls by adding text or buttons on either side of textual inputs, custom file selectors, or custom inputs.
Basic input groups: The following classes are the base classes that are used to add the groups to either side of the input boxes.
- The .input-group-prepend class is used to add groups to the front of the input.
- The .input-group-append class is used to add it behind the input.
- The .input-group-text class is used to style the text that is displayed inside the group.
The following example demonstrates these input groups:
html
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet"
href=
<title>Input Groups in Bootstrap</title>
</head>
<body>
<div class="container">
<h3>Prepend Group Example</h3>
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text"
id="username">
@
</span>
</div>
<input type="text"
class="form-control"
placeholder="Username">
</div>
<h3>Append Group Example</h3>
<div class="input-group">
<input type="text"
class="form-control"
placeholder="Email">
<div class="input-group-append">
<span class="input-group-text"
id="email">
@example.com
</span>
</div>
</div>
<h3>Prepend and Append Together</h3>
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text">

</div>
<input type="text"
class="form-control"
placeholder="Your domain name here">
<div class="input-group-append">
<span class="input-group-text">

</span>
</div>
</div>
</div>
</body>
</html>

Output:
Sizing of the Input Groups
The input groups could be made larger or smaller by additional classes. There are 3 possible sizes of input groups:
- The .input-group-sm class is used for a smaller size.
- The .input-group-lg class is used for a larger size.
- The .input-group class is the default size.
Note: Sizing on the individual input group elements isn’t currently supported.
