Bootstrap is a popular front-end web development framework that helps developers create responsive and mobile-first websites. Bootstrap CDN (Content Delivery Network) is a way to access the Bootstrap files from a server near you, hence speeding up the loading and rendering of the webpage.
When using Bootstrap, you will need to include the CSS files in your project. Instead of downloading and hosting these files yourself, you can use the Bootstrap CDN to link to these files directly from the Bootstrap servers, as shown in the following code snippet:
<!-- Link to Bootstrap CSS via CDN -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
This code will link to the latest version of Bootstrap (version 4.5.2 as of writing), but you can also select an older version or a specific release by adjusting the URL.
Using Bootstrap CDN has several advantages over hosting the files locally:
Faster page loading: By utilizing a CDN, you can ensure that the Bootstrap files are served from a server closer to the user, thus reducing the loading time for the webpage.
Reduced bandwidth usage: Hosting the files locally can consume your bandwidth and slow down your website, especially if you have a lot of traffic.
No maintenance: You do not need to worry about updating or maintaining the Bootstrap files, as they are maintained by the Bootstrap team and automatically updated on the CDN.
In conclusion, using Bootstrap CDN to link to the CSS files is a simple and efficient way of using Bootstrap in your web projects. It provides faster loading times, reduced bandwidth usage, and requires no maintenance on your part. So if you haven't already, give Bootstrap CDN a try in your next web project!
