How to Add Bootstrap Form Component Styling ?

Last Updated : 05 Apr, 2024

Forms play a crucial role in web development, allowing users to interact with websites. By incorporating Bootstrap form component styling, which includes predefined classes like “form-group” for organizing form elements, “form-control” for styling inputs, and “btn” for buttons, we enhance both the functionality and appearance of the forms effortlessly.

Adding Bootstrap Form Component Styling

First, create an HTML structure for your need and add the Bootstrap CDN link in the <head> section of your HTML document using a <link> tag.
After that create a container to hold all the form components using the “container” class.
Then structure your form using HTML form elements such as <form>, <input>, <textarea>, and <button>. Apply Bootstrap classes to these elements for consistent styling.
Here you can utilize Bootstrap’s predefined form control classes to style your form inputs, labels, and buttons. For example, use classes like “form-control” for input fields and “btn” for buttons.
And add the JavaScript code for better interactivity with your form.
