“Website design with Bootstrap has made the dream of responsive design a reality.”
This framework makes the website page or web application adapt to the size and direction of the user’s screen, and there is no need to do things like zooming when viewing the page’s content.
Also, if we want to look at the matter from the aspect of saving time, it is better to proceed with an example:
Suppose you will design a website page about a Python training course. To put together the main elements of this page, you need to use HTML. Of course, you don’t want your page to be book-style and black and white, that’s why you use CSS to style the elements, but if you want to do this faster and the concerns related to the screen size, Don’t have the user and page elements, it’s time to go for Bootstrap.

Why is the Bootstrap framework so popular in the front-end world?
In this section, we discuss the outstanding features that make this framework attractive:
Easy to learn and use process
One of the most important reasons for the popularity of this framework is its simple structure. In this way, the files are presented in a ready and compiled form that beginner developers can easily use, and professional developers can easily customize and make them as they like.
So, if you already have basic knowledge of HTML, CSS, and JavaScript, using Bootstrap is not a complicated task for you. Of course, let’s say you are thinking of starting a simple and essential website that doesn’t need to customize bootstrap files; maybe your work will be solved overnight.
But if you have bigger goals and like to customize Bootstrap elements to your liking, you may need more knowledge and time. Overall, Bootstrap will make the impossible possible for you, provided you have a deeper understanding of its capabilities.
Responsive grading system
The Bootstrap system is in the form of a grid and consists of ready-made columns and rows, which frees the developer from the difficulties of building a basic system. With these ready-made columns and rows, all you have to do is add the content inside the containers, and there is no need to insert media queries inside the CSS file.
Also, this grid simplifies the data entry process because this framework has many media queries that allow you to define column breakpoints based on your needs.
This grid system has two separate container classes for desktop and mobile-based projects. One is fixed-width suitable for desktops, and the other is compatible with all screen sizes by providing a full-width container.
In general, if you stick to the default settings of this framework’s Grady system, you will not get hit because your website’s needs will be met with these defaults, and Bootstrap’s containers and media queries will make your site compliant. Set with a viewport.
Responsive images
Images are among the most important parts of websites and web applications that make them look dull, but a fixed-size photo is not suitable for all screens, and you should also think about their responsiveness when Bootstrap can do this well.
Using ready-made HTML and CSS rules, Bootstrap provides ready-made classes such as img-responsive that automatically resize images based on user screen size.
Of course, although changing the size affects the regular appearance, reducing the size of the images is also on the agenda of these classes, which increases the performance and speed of the pages and helps improve the site’s SEO.
If you are thinking of changing the images’ shape and want to fit the images inside the content of the pages according to your needs, you can use other classes such as img-circle and img-rounded.
Ability to customize
A beginner developer may meet their needs with ready-made Bootstrap classes, but you will not always have the exact conditions. With some knowledge of CSS, you can customize Bootstrap’s visual elements to your liking.
Buttons, navigation bars, menus, and tables are all re-designable, so if you need more information to customize them, don’t worry because the Bootstrap community is so vast. Many websites provide Bootstrap customization codes for free, and you can take the first steps in this direction using them. CodePen is one of the most popular that shares creative ways to customize Bootstrap that you can use to take your Bootstrap project to the next level.

What is the structure of the Bootstrap framework?
Now that we’ve taken an overview of Bootstrap, it’s time to get into the details.
If you want to learn Bootstrap, the first step is to install this framework. If you are starting and don’t think about customizing the components, it is better to ignore the source code version and go to the Bootstrap site and download the compiled version.
When you open the compressed file, you will see two folders, CSS and JS, each of which has its structure:
CSS:
CSS folder files are used to manage the website page layout. When the content and structure of a website are specified with HTML, it is CSS’s turn to do the styling work.
The functions related to this folder help the developer to adjust the appearance of pages, tables, or… more quickly.
For the structure of the whole page, refer the website page to Bootstrap.css, and apply the necessary changes in the CSS file itself.
In general, the files in this section are your cheat sheet, and you can use them to determine the style of the grid structure, tables, images, and other elements on the page.
JS:
The files in this folder are responsible for the website’s interaction; for this reason, it is considered one of the most essential parts.
Developers use the jQuery library to avoid repeating JavaScript syntax and many tasks related to website development, such as creating widgets, creating custom CSS animations, and generally adding dynamic website interactivity. Go ahead with this library.
Although Bootstrap works well with CSS and HTML features, it needs jQuery to make a website look monotonous and static.
How to use Bootstrap in your project?
In general, there are two ways to use Bootstrap:
Download Bootstrap framework
In this method, download the bootstrap file and use the CSS and JS files that are inside this file.
You must call the desired file as follows in the Head section of the HTML file of the page:
<head>
<meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1">
<!-- Bootstrap CSS library -->
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
</head>
This library you have imported has different classes you can apply to style the elements inside the page according to your needs.
For example, in the example below, we have used the text-center class to create a div in the central part of the page, and the text-success class to determine the color (green) and size of the title, and named the file project, along with the JS folders. And we put CSS inside a folder called Bootstrap.
<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset=”utf-8″>
<meta name=”viewport.”
content=”width=device-width, initial-scale=1″>
<!– Bootstrap CSS library –>
<link rel=”stylesheet”
type=”text/CSS.”
href=”css/bootstrap.min.css”>
</head>
<body>
<div class=”container text-center”>
<!– Text color class used –>
<h1 class=”text-success”>First Bootstrap Project</h1>
<p>The first bootstrap project has been successfully created.</p>
</div>
</body>
</html>
This page will be as follows:
Of course, here, we only used the CSS library for styling, and if you want to use the JS library, you need to add two more lines to the code.
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- JavaScript library -->
<script src="js/bootstrap.min.js"></script>Elements such as toggle buttons or sliders require JavaScript, and if you want to use these elements, you must first import the jQuery library and then call the JavaScript library.
2. Using a CDN
If you don’t want to download the bootstrap file and like to call the libraries using links, this method suits you.
In the CDN method, the desired library is downloaded from the nearest server so that accessing and displaying the page is done at a higher speed, which can benefit user satisfaction.
In this method, it is enough to find the link of the desired libraries on sites such as BootstrapCDN and put it in the Head part of the HTML file of the page as follows:
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.4/jquery.min.js"></script>
<!-- Latest compiled JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script >
So, if we want to implement the previous project with CDNs, its source code will be as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport"
content="width=device-width, initial-scale=1">
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.4/jquery.min.js"></script>
<!-- Latest compiled JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></scvs
</head>
<body>
<div class="container text-center">
<!-- Text color class used -->
<h1 class="text-success">First Bootstrap Project (CDN)</h1>
<p>The first bootstrap project has been successfully created.</p>
</div>
</body>
</html>
The page will be as follows:
