Pull request overview

This PR adds a Japanese-themed landing page for Toyotomi Hideyoshi (豊臣秀吉), a historical figure. The implementation includes a modern, responsive design with traditional Japanese aesthetic elements including vertical text orientation, gold and dark color schemes, and smooth scroll animations. The page is built as a static HTML/CSS/JavaScript site added to a repository that previously contained only Python terminal effects code.

Changes:

Created a complete landing page with hero section, navigation, biography, achievements, gallery, and contact form
Implemented responsive design with mobile-friendly breakpoints and animations
Added JavaScript functionality for smooth scrolling, intersection observer animations, and form handling

The copyright year "1598" is historically significant (the year Toyotomi Hideyoshi died), but may confuse users or be flagged by automated tools as an error. Consider using the current year or adding a comment explaining the historical context if this is intentional.

+    animation: rotate 20s linear infinite;
+}


The animation for the kamon (family crest) rotates infinitely for 20 seconds. This continuous animation could be distracting for users with vestibular disorders or motion sensitivity. Consider adding a prefers-reduced-motion media query to disable or reduce this animation for users who have indicated a preference for reduced motion in their system settings.

+                    <button type="submit" class="btn-gold">送信</button>
+                </form>


The form collects email addresses and messages but has no client-side validation beyond the HTML5 required attribute and type="email". While the form submission is mocked, if this were to be connected to a real backend, consider adding input sanitization, CSRF protection, and rate limiting to prevent spam and abuse. Additionally, there's no privacy notice or consent mechanism for data collection.

+    animation: fadeIn 1.5s ease-out 0.5s forwards;

The fade-in animations (.fade-in and .fade-in-delay) use the 'forwards' fill-mode which keeps the final animation state. However, these classes are applied to elements that should always be visible (the hero title and subtitle). If JavaScript is disabled or fails to load, these elements will remain invisible (opacity: 0) permanently. Consider using a noscript fallback or applying a default visible state that only gets overridden when JavaScript is available.

+                    behavior: 'smooth'
+                });


The smooth scrolling implementation uses 'window.scrollTo' which is well-supported in modern browsers. However, the 'behavior: smooth' option is not supported in Safari versions before 15.4 (released March 2022) and Internet Explorer. Consider adding a polyfill or feature detection to gracefully degrade to instant scrolling for browsers that don't support smooth scrolling behavior.

Suggested change

window.scrollTo({

top: targetElement.offsetTop - 60, // Adjust for sticky nav

behavior: 'smooth'

});

const scrollTarget = targetElement.offsetTop - 60; // Adjust for sticky nav

if ('scrollBehavior' in document.documentElement.style) {

window.scrollTo({

top: scrollTarget,

behavior: 'smooth'

});

} else {

window.scrollTo(0, scrollTarget);

+                        <textarea id="message" name="message" rows="4"></textarea>


The textarea element for the message field doesn't have a 'required' attribute like the name and email inputs. This inconsistency means users can submit the form without providing a message. If a message is optional, this is fine, but if it's required, add the 'required' attribute. If it's optional, consider adding helper text to clarify this to users.

Suggested change

<textarea id="message" name="message" rows="4"></textarea>

<textarea id="message" name="message" rows="4" required></textarea>

The placeholder images in the gallery use div elements with gradient backgrounds and text, but lack proper accessibility attributes. These decorative elements should either have role="img" with aria-label attributes describing the content, or be marked as decorative with role="presentation". Additionally, since these are meant to represent images (大阪城, 黄金の茶室, 醍醐の花見), they should have descriptive labels for screen reader users.

The hero background uses a Base64-encoded SVG pattern which adds significant inline data to the CSS file. While this pattern is small, it increases the initial CSS file size and cannot be cached separately. Consider moving this pattern to a separate SVG file that can be cached, or simplifying the pattern if the decorative effect is not critical. This would improve initial page load performance.

The IntersectionObserver API is used without a fallback for older browsers. While IntersectionObserver has good support in modern browsers, it's not available in Internet Explorer 11. Consider adding a polyfill or a graceful fallback that simply shows all elements (by adding the 'visible' class immediately) for browsers that don't support IntersectionObserver. This can be done by checking if 'IntersectionObserver' exists in the window object before using it.

Suggested change

const observerOptions = {

root: null,

rootMargin: '0px',

threshold: 0.1

};

const observer = new IntersectionObserver((entries, observer) => {

entries.forEach(entry => {

entry.target.classList.add('visible');

observer.unobserve(entry.target);

}

});

}, observerOptions);

entry.target.classList.add('visible');

observerInstance.unobserve(entry.target);

}

});

}, observerOptions);

fadeUpElements.forEach(el => {

observer.observe(el);

});

} else {

// Fallback for browsers without IntersectionObserver support

fadeUpElements.forEach(el => {

el.classList.add('visible');

});

The page loads the Wikipedia image for the family crest (五七の桐) from an external domain without a fallback. If Wikimedia Commons is unavailable or the image is moved/deleted, this will result in a broken image. Consider hosting this image locally in the project or adding an onerror handler to display a fallback. Additionally, external images can affect page load performance and introduce a privacy concern as it makes a third-party request.
