# Bootstrap

So it's day 20 already. Finally!!!!

Today we will be talking about Bootstrap. Bootstrap was made by Twitter and it is a frontend development framework that is used to create responsive and mobile-first websites. It is a collection of CSS and JavaScript libraries, used to help create responsive and mobile-friendly interfaces. Elements, components and layouts are pre-designed, and it has reusable bits of code that make it easier and faster to build websites.

**How to use Bootstrap in your code:**

To use Bootstrap, you will have to add the CSS and html bootstrap code in your HTML file. Add it in your head tag, in between the link tags.

```xml
<!DOCTYPE html>
<html>
<head>
    <title>My Website</title>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
</head>
<body>
    <!-- Your content goes here -->
</body>
</html>
```

And there you have it. You are ready to use Bootstrap to start building.
