Reviewer's GuideUpdates Twitter/X social icon usage and implements scroll-based navbar color behavior by introducing a reusable SVG icon, centralized CSS filter rules for different layout regions, and JavaScript scroll handling that toggles navbar state instead of forcing it during load.

Hey there - I've reviewed your changes - here's some feedback:
- The new
DOMContentLoadedhandler assumes.overlay-navalways exists; consider null-checkingnavbefore callingclassList.remove/addto avoid runtime errors on pages without that element. - The CSS for
.social-iconrelies on multiple!importantoverrides for different containers; it might be more maintainable to reduce!importantusage by tightening selectors or using modifier classes to express the state instead. - Now that
$('nav').addClass('show-content')is commented out with an inline note, consider either removing it or replacing it with a conditional that respects the scroll logic, so the behavior is encoded in code rather than in comments.

## Overall Comments
- The new `DOMContentLoaded` handler assumes `.overlay-nav` always exists; consider null-checking `nav` before calling `classList.remove`/`add` to avoid runtime errors on pages without that element.
- The CSS for `.social-icon` relies on multiple `!important` overrides for different containers; it might be more maintainable to reduce `!important` usage by tightening selectors or using modifier classes to express the state instead.
- Now that `$('nav').addClass('show-content')` is commented out with an inline note, consider either removing it or replacing it with a conditional that respects the scroll logic, so the behavior is encoded in code rather than in comments.

**issue (bug_risk):** Guard against missing `.overlay-nav` to avoid runtime errors on pages without that element.
On pages without `.overlay-nav`, `document.querySelector` returns `null`, so `nav.classList.remove` will throw and stop subsequent JS from running. Please add a null check (e.g. `if (!nav) return;`) after the query to make this safe.

**suggestion:** Clarify the `alt` text to better convey the destination/action rather than just the logo name.
Using just "X logo" as the `alt` text doesn’t convey the purpose of the link to screen reader users. Consider something like "FOSSASIA on X (Twitter)" or, for share buttons, "Share on X (Twitter)" so the action/destination is clear.
Suggested implementation:
```
<li><a href="https://twitter.com/fossasia" target="_self"><img src="img/x-logo.svg" alt="FOSSASIA on X (Twitter)" class="social-icon">
</a></li>
```
```
<a target="_blank" href="https://twitter.com/fossasia"><img src="img/x-logo.svg" alt="FOSSASIA on X (Twitter)" class="social-icon">
</a>
```
```
<img src="img/x-logo.svg" alt="FOSSASIA on X (Twitter) feed" class="social-icon">
```
