Offcanvas Sidebar Behavior

This section describes the interactive behavior of the Bootstrap 5.3 offcanvas sidebar when used on screens 1129px wide and below.

• Toggler icon opens the sidebar and dims the background
• Close button hides the sidebar and removes the dim
• Clicking outside the sidebar closes it and removes the dim
• Clicking non-dropdown links inside the sidebar:
  • Closes the sidebar
  • Navigates to the section
  • Removes the dim
• Clicking a dropdown link inside the sidebar:
  • Expands the dropdown
  • Shows the child items
  • Keeps the sidebar open
• Clicking a dropdown child item:
  • Closes the sidebar
  • Navigates to the section
  • Removes the dim

Search Modal

Details on how the Search modal behaves in various user actions.

• Modal closes when:

  • User clicks the close button
  • User clicks outside modal
  • User presses "Search"
  • User types a query and presses Enter

• Modal stays open if:

  • User presses Enter with an empty Search field

Login/Signup Modals

This script handles the opening, closing, panel-switching, and form validation behavior for the Login and Signup modal.

Opening Modals

• Open and Close Modal

  • Clicking the login icon opens the modal and defaults to the Login panel.
  • Clicking the close button or clicking outside the modal closes it.
  • When the modal closes, all input fields in both panels are cleared.

• Switch Between Panels

  • Users can toggle between Login and Signup without restriction.
  • Switching panels also resets validation states and form fields.

Form Reset on Close

Closing the modal:

• Clears all input values.
• Resets validation state and active panel to Login.

Login Validation

Pressing Enter or clicking Continue checks that the Username field is not empty.

• If empty:
  • Native browser validation is triggered.
  • Default form submission is blocked.

Validation uses HTML5 form validation (required attribute) to show browser-native warning like:

• "Please fill out this field"

Signup Validation

info

This is still a work in progress.

Sequential field validation: Prevents submitting the form (via Enter or "Sign Up" button) unless the following fields are all filled:

• Full Name
• Email Address
• Username
• Password

The first empty required field triggers the browser's built-in validation message.

• Uses checkValidity() on the form
• Ensure native handling of "Please fill out this field".

Banner (Video Hero Section)

The banner is a full-width hero section that creates an engaging first impression using a background video and a prominent message overlay. It provides key calls-to-action to guide user interaction.

• Background video

  • Plays automatically, loops continuously, and remains muted
  • Provides a modern, dynamic visual to capture attention

• Fallback image

  • Displays when video is unsupported or loading
  • Ensures consistent visual presentation across all devices

• Overlay content

  • Bold headline to introduce the brand message
  • Descriptive paragraph explaining the service value
  • Two prominent buttons:
    • “See solutions” directs users to the shipping services section
    • “Talk to us” connects users to the support section

• Responsive layout

  • Content and visuals adjust gracefully across screen sizes
  • Ensures readability and interaction on both desktop and mobile devices

Responsiveness

The layout uses Bootstrap grid and utility classes to ensure mobile-friendliness:

• Text and buttons are center-aligned
• Video and image scale responsively to fit different screen sizes
• Overlay adapts its size and alignment on smaller viewports

Additional Notes

The banner section is optimized for performance and accessibility.

• Autoplay settings comply with modern browser policies.
• Fallback visuals ensure compatibility.
• The calls-to-action are placed to drive engagement and support navigation flow.

Carousel

The carousel section features an auto-sliding image gallery with manual navigation controls for a dynamic user experience.

• Automatic slide transition

  • Slides change every 3 seconds
  • Pauses on hover is disabled for continuous motion

• Navigation buttons

  • Previous and Next buttons allow manual navigation
  • Icons for intuitive control

• Indicators

  • Shows clickable buttons to jump to specific slides
  • Active slide is clearly highlighted

• Responsive design

  • Ensures smooth experience across all devices
  • Images scale accordingly for different screen sizes

Country Dropdown

Dynamically Populate Countries

To dynamically populate the country dropdown, I used a country-fetching Javscript:

• Fetch the list of countries using the Intl.DisplayNames API.
• Sort them alphabetically.
• Inject them into the <select id="country"> dropdown.

Initial script:

document.addEventListener("DOMContentLoaded", function () {
  const countrySelect = document.getElementById("country");

  const placeholderOption = countrySelect.options[0];
  countrySelect.innerHTML = "";
  countrySelect.appendChild(placeholderOption);

  // Get country names using Intl API
  const regionNames = new Intl.DisplayNames(['en'], { type: 'region' });

  const countries = Array.from(
    new Set(
      Intl.supportedValuesOf('region')
        .filter(code => /^[A-Z]{2}$/.test(code)) // Ensure ISO country codes
    )
  ).map(code => regionNames.of(code));

  // Sort alphabetically
  countries.sort((a, b) => a.localeCompare(b));

  // Append countries to the dropdown
  countries.forEach(country => {
    const option = document.createElement("option");
    option.value = country;
    option.textContent = country;
    countrySelect.appendChild(option);
  });
});

Then configured the section in HTML:

<body>
  <!-- Other sections above -->

    <div class="form-group">
      <div class="custom-select 
                  supp-sec-3-select-wrapper">
        <select class="form-control" 
                id="country">
          <option value="" disabled selected>Country/Region</option>
        </select>
        <img src="./icons/arrow-down.svg" class="dropdown-arrow" alt="arrow icon">
      </div>
    </div>

  <!-- Other sections below -->

  <script src="./src/js/fetch-countries.js"></script>

</body>

To use this approach, the browser must support the Intl.DisplayNames and Intl.supportedValuesOf APIs (available in Chrome 102+, Edge 102+, Firefox 103+, Safari 15.4+). I gave it a try, but it didn’t work, so I did some troubleshooting:

• Opened the browser’s DevTools → Console
• Noticed errors like Uncaught ReferenceError and 404s in the Network tab

To confirm support, run this in the console:

Intl.supportedValuesOf('region')

If your browser doesn’t support it, you’ll see an error like this:

Or from the script:

fetch-countries.js:14 Uncaught RangeError: Invalid key : region
    at Intl.supportedValuesOf (<anonymous>)
    at HTMLDocument.<anonymous> (fetch-countries.js:14:12)
(anonymous)	@	fetch-countries.js:14 

Error:

Uncaught RangeError: Invalid key : region

This confirms the API isn’t supported in the current browser.

Workaround: Use a fallback list of country codes instead.

Using a Static Country List

Instead of using an API, I opted for using a static list of country codes. The script below populates a select dropdown with all countries using ISO 3166-1 alpha-2 codes and their display names.

• Generates country names from ISO codes
• Clears default options except placeholder
• Sorts country names alphabetically
• Appends each country as an option in the dropdown

This provides accurate, localized country listing without external APIs.

document.addEventListener("DOMContentLoaded", function () {
  const countrySelect = document.getElementById("country");

  // Save and clear the placeholder
  const placeholder = countrySelect.querySelector("option[disabled]");
  countrySelect.innerHTML = "";
  countrySelect.appendChild(placeholder);

  const regionNames = new Intl.DisplayNames(['en'], { type: 'region' });

  // Full ISO 3166-1 alpha-2 country code list
  const countryCodes = [
    "AF","AX","AL","DZ","AS","AD","AO","AI","AQ","AG","AR","AM","AW","AU","AT","AZ",
    "BS","BH","BD","BB","BY","BE","BZ","BJ","BM","BT","BO","BQ","BA","BW","BV","BR",
    "IO","BN","BG","BF","BI","KH","CM","CA","CV","KY","CF","TD","CL","CN","CX","CC",
    "CO","KM","CG","CD","CK","CR","CI","HR","CU","CW","CY","CZ","DK","DJ","DM","DO",
    "EC","EG","SV","GQ","ER","EE","SZ","ET","FK","FO","FJ","FI","FR","GF","PF","TF",
    "GA","GM","GE","DE","GH","GI","GR","GL","GD","GP","GU","GT","GG","GN","GW","GY",
    "HT","HM","VA","HN","HK","HU","IS","IN","ID","IR","IQ","IE","IM","IL","IT","JM",
    "JP","JE","JO","KZ","KE","KI","KP","KR","KW","KG","LA","LV","LB","LS","LR","LY",
    "LI","LT","LU","MO","MG","MW","MY","MV","ML","MT","MH","MQ","MR","MU","YT","MX",
    "FM","MD","MC","MN","ME","MS","MA","MZ","MM","NA","NR","NP","NL","NC","NZ","NI",
    "NE","NG","NU","NF","MK","MP","NO","OM","PK","PW","PS","PA","PG","PY","PE","PH",
    "PN","PL","PT","PR","QA","RE","RO","RU","RW","BL","SH","KN","LC","MF","PM","VC",
    "WS","SM","ST","SA","SN","RS","SC","SL","SG","SX","SK","SI","SB","SO","ZA","GS",
    "SS","ES","LK","SD","SR","SJ","SE","CH","SY","TW","TJ","TZ","TH","TL","TG","TK",
    "TO","TT","TN","TR","TM","TC","TV","UG","UA","AE","GB","US","UM","UY","UZ","VU",
    "VE","VN","VG","VI","WF","EH","YE","ZM","ZW"
  ];

  const countries = countryCodes.map(code => ({
    code,
    name: regionNames.of(code)
  }));

  countries.sort((a, b) => a.name.localeCompare(b.name));

  countries.forEach(({ name }) => {
    const option = document.createElement("option");
    option.value = name;
    option.textContent = name;
    countrySelect.appendChild(option);
  });
}); 

Switching from ID to Class

To improve reusability, I updated the script to use a class selector instead of a specific ID. This allows the same logic to apply to multiple dropdowns on the page.

• Replaced getElementById with querySelectorAll to select all elements with a specific class
• Used forEach to loop through and populate each matching dropdown

This version supports multiple dropdowns with the class country-select, which makes the script modular and reusable across different parts of the page.

document.addEventListener("DOMContentLoaded", function () {
  const selects = document.querySelectorAll(".country-select");
  const regionNames = new Intl.DisplayNames(['en'], { type: 'region' });
  const countryCodes = [ /* ISO 3166-1 alpha-2 list here */ ];

  const countries = countryCodes.map(code => ({
    code,
    name: regionNames.of(code)
  })).sort((a, b) => a.name.localeCompare(b.name));

  selects.forEach(countrySelect => {
    const placeholder = countrySelect.querySelector("option[disabled]");
    countrySelect.innerHTML = "";
    if (placeholder) countrySelect.appendChild(placeholder);

    countries.forEach(({ name }) => {
      const option = document.createElement("option");
      option.value = name;
      option.textContent = name;
      countrySelect.appendChild(option);
    });
  });
});

Responsive Web Design

Common Screen Widths

Device Type	Screen Width (CSS px)	Example Devices
Small phones	320px	iPhone SE (1st gen), older Androids
Compact phones	360px – 375px	iPhone SE (2022), Pixel 4a, Galaxy A series
Average smartphones	390px – 414px	iPhone 13/14, Galaxy S23, Pixel 7
