Source Code

Step 1 (HTML Code):

To begin, create a new directory for your project and set up the necessary files. You'll need an HTML file for the structure, a CSS file for styling, and a Javascript file for adding functionality.

Start by defining the structure of your booking app UI using HTML. This includes elements such as forms for inputting booking details, buttons for submitting bookings, and containers for displaying information.

Here's a breakdown of the HTML code:

1. <!DOCTYPE html>: This declaration specifies the document type and version of HTML being used.

2. <html lang="en">: This is the root element of the HTML document, specifying the language of the document as English.

3. <head>: This section contains metadata about the HTML document, such as character encoding, viewport settings, and links to external resources.

  • <meta charset="UTF-8">: Specifies the character encoding of the document as UTF-8.
  • <meta name="viewport" content="width=device-width, initial-scale=1.0">: Specifies the viewport settings for responsive design.
  • <title>Booking App UI</title>: Sets the title of the web page.
  • <link rel="stylesheet" href="styles.css">: Links an external CSS file (styles.css) for styling the HTML content.

4. <body>: This section contains the main content of the web page.

  • <div class="app-container">: Acts as a container for the entire application.
  • <section class="navigation">: Represents the navigation section of the application.
  • Various navigation links and buttons.
  • <section class="app-actions">: Represents the action buttons and search functionality.
  • Search input, location button, search button, contact actions, and social media links.
  • <section class="app-main">: Represents the main content area of the application.
  • Cards displaying hotel information with images, names, locations, and prices.
  • <div id="modal-window" class="shadow">: Represents a modal window that opens when a card is clicked, displaying detailed information about a specific hotel.
  • Information such as image, name, location, price, description, and reviews are displayed.
  • Options to book the hotel and add it to favorites are provided.

Step 2 (CSS Code):

Once the structure is in place, use CSS to style the elements and create an appealing visual design. Consider factors such as color scheme, typography, and layout to enhance the user experience.

Here's a breakdown of the CSS code:

1. Importing Fonts: The @import rule imports the Quicksand font family from Google Fonts.

2. Global Styling:

  • *: Applies the following styles to all elements.
  • box-sizing: Ensures that padding and border are included in the element's total width and height.
  • outline: Removes default outline styles.

3. :root: Sets global CSS variables that can be reused throughout the stylesheet. These variables define colors and other design properties.

  • font-family: Sets the default font family to Quicksand or a generic sans-serif if Quicksand is not available.
  • Various custom properties define colors, background colors, border colors, and other design elements.

4. Dark Mode Styling:

  • .dark:root: Overrides the default variables for dark mode.

5. Navigation Styling:

  • .nav-right-side: Styles the right side of the navigation bar.
  • .mode-switch: Styles the dark mode switch button.
  • .nav-link: Styles navigation links.

6. Profile Button Styling:

  • .profile-btn: Styles the profile button with an image.

7. Search Styling:

  • .search-wrapper and .search-input: Styles the search input field and wrapper.

8. App Actions Styling:

  • .app-actions: Styles the container for various actions in the application.

9. Card Styling:

  • .cards-area and .card-wrapper: Styles for the container and individual cards.
  • .card: Styles for card appearance, including background color and border radius.
  • .card-info: Styles for the information section within a card.

10. Modal Styling:

  • .main-modal: Styles for the main modal container.
  • .modal-image-wrapper: Styles for the image container within the modal.
  • .modal-left and .modal-right: Styles for the left and right sides of the modal.
  • .btn-close: Styles for the close button of the modal.

11. Media Queries: Responsive styling for different screen sizes.

Step 3 (JavaScript Code):

Next, use Javascript to add interactive features to your booking app UI.

Here's a breakdown of the JS code:

1. DOMContentLoaded Event Listener:

  • This event listener waits for the HTML document to be fully loaded before executing the enclosed function.
  • Inside this function, it selects an element with the class .mode-switch and adds a click event listener to it. When clicked, it toggles the dark class on the <html> element.

2. openModal() Function:

  • This function selects an element with the ID modal-window and adds the class showModal to it, making it visible.

3. closeM() Function:

  • This function removes the class showModal from the element with the ID modal-window, hiding it.

4. mode-switch Event Listener:

  • This event listener attempts to attach a click event listener to elements with the class .mode-switch, but it's done incorrectly. getElementsByClassName returns a collection, not a single element, so the assignment won't work as intended.

5. cardItems Event Listeners:

  • This code selects all elements with the class .main-card.
  • It attaches a click event listener to each of these elements.
  • When clicked, it selects certain elements within the clicked card, such as .cardText-js and .card-price, and updates the text content of elements with classes .modalHeader-js and .amount respectively with the text content of the clicked card's elements.

6. Keyboard Event Listener:

  • Listens for the keydown event on the window.
  • When the escape key (keyCode 27) is pressed, it calls the closeM() function to hide the modal.

7. Window Click Event Listener:

  • Listens for clicks on the window.
  • If the click target is modal (identified by the modal variable), it calls the closeM() function to hide the modal.
document.addEventListener('DOMContentLoaded', function () {
  var modeSwitch = document.querySelector('.mode-switch');

  modeSwitch.addEventListener('click', function () {
    document.documentElement.classList.toggle('dark');
  });
});

function openModal(){
  let modal= document.querySelector('#modal-window');
  modal.classList.add("showModal");
}

function closeM(){
    let m= document.querySelector('#modal-window');
  m.classList.remove("showModal");
}

document.getElementsByClassName('.mode-switch').onclick = function() {
  document.body.classList.toggle('dark');
}

const cardItems = document.querySelectorAll('.main-card');
const modalHeader = document.querySelector('.modalHeader-js');
const modalCardPrice = document.querySelector('.amount');

cardItems.forEach((cardItem) => {
  cardItem.addEventListener('click', function () {
    const cardHeader = cardItem.querySelector('.cardText-js');
    const cardPrice = cardItem.querySelector('.card-price');

    modalHeader.innerText = cardHeader.innerText;
    modalCardPrice.innerText = cardPrice.innerText;
  });
});

window.onkeydown = function (event) {
  if(event.keyCode == 27) {
    closeM();
  }
}

var modal =  document.querySelector('#modal-window');
window.onclick = function (event) {
  if(event.target == modal) {
    closeM();
  }
}
