HTML Code Improvements and Best Practices Suggestions

[gstarv]

Description:
After reviewing the current HTML code, I noticed some areas that could be improved for better accessibility, security, and performance. Below are my suggestions:

1. HTML Validation Errors:

The lang attribute in the tag should use a valid language code like en-US instead of just en, especially if the dialect is known.

IDs such as 🔧-core-blockchain-features and 🤖-ai-integration-features contain emojis. While technically valid, they could cause issues in older browsers or parsing tools. Consider replacing them with conventional IDs, e.g., core-blockchain-features.

2. Missing alt Attributes:

tags should include descriptive alt attributes for accessibility and SEO. For instance:

3. Potential Script Execution Issues:

Ensure the app object is defined before it is referenced in <script> code inside . For example, app.showPage() should not execute until the object is properly initialized.

Avoid relying on fixed delays like setTimeout(500ms) to wait for the object; an event-based approach would be more reliable.

4. JavaScript Error Handling:

Wrap <script> code in a try...catch block to gracefully handle errors:

try {
document.documentElement.dataset.theme = localStorage.getItem("tsd-theme") || "os";
document.body.style.display = "none";
setTimeout(() => app ? app.showPage() : document.body.style.removeProperty("display"), 500);
} catch (error) {
console.error("Error initializing the page:", error);
}

5. Security Concerns:

Avoid inline JavaScript to reduce XSS vulnerabilities. Move inline scripts to external files where possible.

Sanitize and validate all user inputs, especially those that interact with localStorage or the DOM.

6. Accessibility Improvements:

Add aria-label or title attributes to icons for better accessibility. For instance:

7. SEO and Usability:

Enhance the description for clarity and keyword relevance. For example:

8. Performance Optimization:

Use the async or defer attribute for all <script> tags unless immediate execution is necessary.

Benefits:
These changes will:

Improve accessibility and usability for all users.

Increase compliance with web standards and validation tools.

Mitigate security vulnerabilities and improve performance.
