The basic structure of a Bootstrap 3 page




A Bootstrap 3 page consists of two main sections: the head section and the body section. The head section contains the meta information, the title, and the links to the Bootstrap files and other resources. The body section contains the actual content and layout of your page.


The head section




The head section of a Bootstrap 3 page should look something like this:


<head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Your page title</title> <!-- Link to the Bootstrap CSS file --> <link rel="stylesheet" href=" <!-- Link to your own custom CSS file (optional) --> <link rel="stylesheet" href="style.css"> </head>


The meta tags are important for ensuring that your page is responsive and compatible with different devices and browsers. The viewport meta tag tells the browser how to scale and render your page according to the device width and zoom level. The charset meta tag specifies the character encoding of your page, which is usually utf-8.


The title tag defines the title of your page, which is displayed in the browser tab or window. The link tags link to the Bootstrap CSS file and your own custom CSS file (if you have one). You can use either a local or a CDN link to the Bootstrap CSS file, depending on how you downloaded or installed Bootstrap 3.


The body section




The body section of a Bootstrap 3 page should look something like this:


<body> <!-- Your navigation bar goes here --> <nav > ... </nav> <!-- Your main content goes here --> <div > ... </div> <!-- Link to jQuery --> <script src=" <!-- Link to the Bootstrap JavaScript file --> <script src=" </body>


The body section contains your navigation bar and your main content. The navigation bar is usually placed at the top of your page and it contains the links to the different sections or pages of your website. You can use the Bootstrap classes and components to create a responsive and stylish navigation bar. For example, you can use the tag with the class "navbar navbar-default" to create a basic navigation bar. You can also use other classes and components, such as "navbar-brand", "navbar-header", "navbar-toggle", "collapse", "navbar-nav", "dropdown", and more, to customize your navigation bar.


The main content is usually placed inside a tag with the class "container". This creates a fixed-width container that centers your content and adds some padding around it. You can also use the class "container-fluid" to create a full-width container that spans the entire width of your viewport. Inside the container, you can use the Bootstrap grid system to create rows and columns for your layout.


The grid system




The grid system is one of the most powerful features of Bootstrap 3. It allows you to create res
