Creating a Bootstrap Form Range Input

This guide discusses how to create a range input (slider) in Bootstrap forms, enabling users to visually select a value from a specified range.

Key Concepts

• Bootstrap: A popular front-end framework that simplifies web development through pre-designed components and styles.
• Form Range Input: An input type that allows users to select a number from a range, represented visually as a slider.

Creating a Range Input

Basic Structure

To create a range input in Bootstrap, you can use the following HTML structure:

<div class="form-group">
  <label for="customRange1">Example Range</label>
  <input type="range" class="form-control-range" id="customRange1">
</div>

Attributes

• type="range": Specifies that the input is a range slider.
• class="form-control-range": Applies Bootstrap styles to the range input.

Example

Here’s a complete example of a range input within a Bootstrap form:

<form>
  <div class="form-group">
    <label for="customRange1">Example Range</label>
    <input type="range" class="form-control-range" id="customRange1" min="0" max="100" step="1" value="50">
  </div>
</form>

Attributes Explained

• min: The minimum value of the range (e.g., 0).
• max: The maximum value of the range (e.g., 100).
• step: The increment value (e.g., 1).
• value: The default value when the slider is loaded (e.g., 50).

Conclusion

Using Bootstrap to create a form range input is straightforward and enhances user experience by providing a visual way to select values. This component is especially useful in scenarios where numerical input needs to be constrained to a specific range.
