Containers and Break Points

Containers and Breakpoints

In Tailwind CSS, containers and breakpoints are used to create responsive webpages.

Responsive design means:

webpages automatically adjust for different screen sizes
layouts work properly on:
- mobile phones
- tablets
- laptops
- desktops

What is a Container?

A container is used to:

wrap webpage content
center content
maintain proper width

Without a container:

content stretches fully across the screen

With a container:

content stays properly aligned and centered

Example: Container

<!DOCTYPE html>
<html>
<head>
  <title>Container Example</title>

  <script src="https://cdn.tailwindcss.com"></script>
</head>

<body class="bg-gray-100">

  <div class="container mx-auto bg-white p-6">

    <h1 class="text-2xl font-bold mb-4">
      Tailwind Container
    </h1>

    <p>
      This content is inside a Tailwind container.
    </p>

  </div>

</body>
</html>

What are Breakpoints?

Breakpoints are used to apply styles for different screen sizes.

Tablet	Extra Large
Laptop/Desktop	Very Large
