Source Code

Step 1 (HTML Code):

To get started, we will first need to create a basic HTML file. In this file, we will include the main structure for our e-commerce website.

After creating the files just paste the following codes into your file. Make sure to save your HTML document with a .html extension, so that it can be properly viewed in a web browser.

Let's break it down step by step:

1. <!DOCTYPE html>: This declaration specifies that the document is an HTML5 document.

2. <html lang="en">: This opening <html> tag defines the beginning of the HTML document. The lang attribute indicates that the document's primary language is English.

3. <head>: This is the start of the document's head section, which contains meta-information about the document, such as character encoding, viewport settings, and external resources.

  • <meta charset="UTF-8">: This meta tag specifies the character encoding used in the document, which is UTF-8 (a widely used character encoding).
  • <meta http-equiv="X-UA-Compatible" content="IE=edge">: This meta tag instructs Internet Explorer to use its latest rendering engine (Edge mode) to display the page.
  • <meta name="viewport" content="width=device-width, initial-scale=1.0">: This meta tag sets the viewport settings for responsive design. It ensures that the page scales properly on different device screens.
  • <title>Anon - eCommerce Website</title>: This tag sets the title of the web page, which appears in the browser's title bar or tab.
  • <link rel="shortcut icon" href="favicon.ico" type="image/x-icon">: This link tag specifies the website's favicon, which is the small icon displayed in the browser tab.
  • <link rel="stylesheet" href="styles.css">: This link tag links an external CSS stylesheet (styles.css) to the HTML document for styling.
  • <link rel="preconnect" href="https://fonts.googleapis.com">: These link tags specify preconnect hints for faster loading of external resources, in this case, Google Fonts.
  • <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>: Another preconnect hint for Google Fonts, including the crossorigin attribute.
  • <link href="https://fonts.googleap..." rel="stylesheet">: This link tag loads a specific Google Font (Poppins) with various font weights.

4.<body>: The <body> tag encloses the content that is displayed on the web page.

  • Within the <body> tag, there are various <div> elements and other HTML elements that structure the content of the page.
  • These include a modal for newsletter subscription, notification toasts, a header section with navigation links and a search bar, a main content section with banners, product categories, featured products, testimonials, and a blog section, and finally, a footer with brand categories and navigation links.

5. <script src="script.js"></script>: This script tag links an external JavaScript file (script.js) to the HTML document for adding interactivity and functionality to the website.

6. <script type="module" src="https://unpkg.com/ion...icons.esm.js"></script>: This script tag imports the Ionicons library as an ES module for using iconography in the website.

7. <script nomodule src="https://unpkg.com/ion...icons.js"></script>: This script tag provides a non-module fallback for older browsers that don't support ES modules when using Ionicons.

This is the basic structure of our e-commerce website using HTML, and now we can move on to styling it using CSS.

Step 2 (CSS Code):

Once the basic HTML structure of the e-commerce website is in place, the next step is to add styling to the website using CSS. CSS allows us to control the visual appearance of the website, including things like layout, color, and typography.

Next, we will create our CSS file. In this file, we will use some basic CSS rules to style our website. Let's break down what each part of the code does:

Custom Variables: The code defines several custom variables using the -- prefix, like --spanish-gray, --sonic-silver, --eerie-black, and so on. These variables store values like colors, font sizes, font weights, and border radii.

Global Reset: The code selects all elements (including pseudo-elements ::before and ::after) and applies a global reset to remove margins and padding, ensuring a consistent starting point for styling.

Link Styles: Styles the anchor (a) element to remove underlines from links.

List Styles: Styles the list items (li) to remove default list markers (bullets or numbers).

Button Styles: Styles the button element to reset its appearance, remove the background, borders, and make it cursor:pointer for better interactivity.

Display Styles: Sets various elements (img, ion-icon, button, and a) to have a display of block, which means they will stack vertically, one below the other.

Font Styles: Sets the font-family for the html element to "Poppins" and defines some scrolling behavior properties.

Input Styles: Styles input elements and its placeholder text to inherit the font properties.

Body Background: Sets the background color of the body to a white color using the custom variable --white.

Scrollbar Styles: Styles the scrollbar of the page using vendor-specific pseudo-elements (body::-webkit-scrollbar, body::-webkit-scrollbar-track, body::-webkit-scrollbar-thumb). These styles affect the appearance of the browser's scrollbars.

Container Styles: Defines a class .container with padding to be used for layout purposes.

Scrollbar Behavior: Defines styles for scrollable elements with scrollbars, including the width and appearance of the scrollbar thumb.

Title Styles: Styles a class .title with specific font properties, color, and border-bottom to create a title-like appearance.

Overlay Styles: Styles a class .overlay to create a transparent overlay for modal dialogs. It starts with an opacity of 0 and becomes fully visible when it has the class .active.

Modal Styles: Styles a class .modal for modal dialogs, making it initially invisible (opacity: 0) and hidden. It becomes visible when it has the class .active.

Modal Animation: Defines CSS animations (@keyframes) for modal dialogs to control their appearance and disappearance with a fade-in effect.

Modal Close Button Styles: Styles a close button within modals, including background color and hover effect.

Newsletter Styles: Styles for a newsletter subscription form.

Notification Toast Styles: Styles for notification toast messages that appear at the bottom of the page. These notifications have a sliding-in animation.

Header Styles: Styles for a website header, including logo, search box, and navigation menu.

Step 3 (JavaScript Code):

Finally, we need to create a function in JavaScript. Let's break it down step by step:

1. 'use strict';: This is a directive that enforces strict mode in JavaScript. It helps catch common coding mistakes and prevents the use of undeclared variables.

2. Modal Section:

  • modal, modalCloseBtn, and modalCloseOverlay are variables that store references to HTML elements with specific data attributes.
  • modalCloseFunc is a function that adds a 'closed' class to the modal element, presumably to close a modal dialog.

3. Event Listeners for Modal:

  • modalCloseOverlay and modalCloseBtn are configured to trigger the modalCloseFunc function when they are clicked. This means clicking either the modal overlay or a close button will close the modal.

4. Notification Toast Section:

  • notificationToast and toastCloseBtn are variables that store references to HTML elements with specific data attributes.
  • An event listener is set up on toastCloseBtn, so when it is clicked, a 'closed' class is added to notificationToast to hide it.

5. Mobile Menu Section:

  • Several variables are defined to work with mobile menus.
  • A loop iterates through the mobileMenuOpenBtn elements.
  • For each button, a mobileMenuCloseFunc function is defined, which removes the 'active' class from a corresponding mobile menu and an overlay.
  • Event listeners are added to the mobile menu open button, close button, and overlay. Clicking the open button adds the 'active' class to the mobile menu and overlay, while clicking the close button or overlay removes it.

6. Accordion Section:

  • Variables are defined to work with accordion elements.
  • A loop iterates through the accordionBtn elements.
  • For each button, an event listener is added. When a button is clicked, it checks whether its associated accordion content is already active. If it is, it does nothing (presumably to allow toggling). If not, it deactivates all other accordions and activates the clicked one.

Create a JavaScript file with the name script.js and paste the given codes into your JavaScript file and make sure it's linked properly to your HTML document so that the scripts are executed on the page. Remember, you’ve to create a file with .js extension.

'use strict';

// modal variables
const modal = document.querySelector('[data-modal]');
const modalCloseBtn = document.querySelector('[data-modal-close]');
const modalCloseOverlay = document.querySelector('[data-modal-overlay]');

// modal function
const modalCloseFunc = function () { modal.classList.add('closed') }

// modal eventListener
modalCloseOverlay.addEventListener('click', modalCloseFunc);
modalCloseBtn.addEventListener('click', modalCloseFunc);

// notification toast variables
const notificationToast = document.querySelector('[data-toast]');
const toastCloseBtn = document.querySelector('[data-toast-close]');

// notification toast eventListener
toastCloseBtn.addEventListener('click', function () {
  notificationToast.classList.add('closed');
});

// mobile menu variables
const mobileMenuOpenBtn = document.querySelectorAll('[data-mobile-menu-open-btn]');
const mobileMenu = document.querySelectorAll('[data-mobile-menu]');
const mobileMenuCloseBtn = document.querySelectorAll('[data-mobile-menu-close-btn]');
const overlay = document.querySelector('[data-overlay]');

for (let i = 0; i < mobileMenuOpenBtn.length; i++) {

  // mobile menu function
  const mobileMenuCloseFunc = function () {
    mobileMenu[i].classList.remove('active');
    overlay.classList.remove('active');
  }

  mobileMenuOpenBtn[i].addEventListener('click', function () {
    mobileMenu[i].classList.add('active');
    overlay.classList.add('active');
  });

  mobileMenuCloseBtn[i].addEventListener('click', mobileMenuCloseFunc);
  overlay.addEventListener('click', mobileMenuCloseFunc);

}

// accordion variables
const accordionBtn = document.querySelectorAll('[data-accordion-btn]');
const accordion = document.querySelectorAll('[data-accordion]');

for (let i = 0; i < accordionBtn.length; i++) {

  accordionBtn[i].addEventListener('click', function () {

    const clickedBtn = this.nextElementSibling.classList.contains('active');

    for (let i = 0; i < accordion.length; i++) {

      if (clickedBtn) break;

      if (accordion[i].classList.contains('active')) {

        accordion[i].classList.remove('active');
        accordionBtn[i].classList.remove('active');

      }

    }

    this.nextElementSibling.classList.toggle('active');
    this.classList.toggle('active');

  });

}
