  • The HTML file sets up the structure of the web page, including references to external CSS and JavaScript files, as well as external resources like the Swiper CSS and Font Awesome for icons.
  • It defines a container with a header, logo, and an image slider section.
  • Inside the image slider section, individual cards are created using the Swiper structure, and each card contains an image and a “Book Tour” button.

  • The CSS file defines styles optimized for the project, including font imports, base styling, variables for colors and fonts, and styles for the container, header, logo, and cards.
  • It also includes styles for the navigation buttons and scrollbar of the Swiper image slider.


// Swiper JavaScript Code
let swiperCards = new Swiper(".cards", {
    loop: true,
    spaceBetween: 32,
    grabCursor: true,
    navigation: {
      nextEl: ".swiper-button-next",
      prevEl: ".swiper-button-prev",

    scrollbar: {
      el: '.swiper-scrollbar',
      draggable: true,
  • The JavaScript file initializes Swiper, the image slider library.
  • It sets options such as loop, space between images, and navigation controls (next and previous buttons).
  • Additionally, it configures a scrollbar to enable users to scroll through the images.

This web application provides users with an interactive image slider featuring multiple images, each accompanied by a “Book Tour” button. The project’s structure and styling have been optimized and well-commented for clarity and a visually appealing user experience. You can customize it further to suit your needs.
