How to Apply Bootstrap CSS Styles Selectively?

Applying Bootstrap CSS Styles Selectively

Problem Statement:

How can CSS styles from the Twitter Bootstrap framework be applied only to specific sections of a website, while leaving other elements unaffected?

Solution with Less:

Bootstrap 3 can be easily customized using Less, a dynamic stylesheet language. The following steps outline how to selectively apply Bootstrap styles:

1. Download the Bootstrap source code.
2. Create a .less file (e.g., style.less) with the following content:

.bootstrap {
    @import "/path-to-bootstrap-less.less";
    @import "/path-to-bootstrap-responsive-less.less";
}

3. Compile the .less file using Less or Node.js (npm).

Custom CSS Prefix (If Less is Not Available):

If Less is not an option, it is possible to manually extract and modify CSS styles. However, this process can be time-consuming and error-prone. A free tool such as CSS Prepend can be used to automatically add a custom prefix (e.g., .bootstrap) to all CSS rules, allowing for selective application.
