Hey @Zache, I've added a search button to improve mobile usability.

Changes:
Added button in JS: code diff
Responsive CSS: code diff

Elements in searchInputContainer stay inline down to 150px width, then wrap cleanly. I made sure all existing functionality works properly while adding button support.
Please review it and let me know if you'd like any adjustments!

Thank you, I will check it!

Hey @Shellygarg10, I’d use a real form, both for accessibility and to make the code simpler (including the removal of a basically copy-pasted event handler):

• $searchInputContainer would be a <form> instead of a <div>;
• $searchButton would have type: 'submit' instead of type: 'button';
• the click handler of $searchButton would call .preventDefault() on its first parameter to avoid submitting the form to the server;
• and the keypress could be removed from $searchInput – with this thing being a form, pressing Enter activates the submit button automatically (but doesn’t activate a button button, which is why its type needs to be changed), so we don’t have to intercept it on our own.

Hey @Tacsipacsi,
Thank you for the guidance! I've implemented the improvements exactly as you suggested. The functionality remains the same.
