/* =================================================================
   GLOBAL.CSS - Combined styles from index.html and blog.ejs
   =================================================================
   
   CẢNH BÁO - CONFLICTING CLASS NAMES:
   
   Các class sau đây có tên trùng nhau nhưng styles khác nhau:
   
   1. .container - Có 2 styles khác nhau (search page vs blog page)
   2. .search-input-wrapper - Có 2 styles khác nhau 
   3. .search-input - Có 2 styles khác nhau
   4. .search-icon-wrapper - Có 2 styles khác nhau
   5. .search-icon - Có 2 styles khác nhau
   6. .footer - Có 2 styles khác nhau (search page vs blog page)
   7. .footer-link - Có 2 styles khác nhau
   8. .blog-description - Có 2 styles khác nhau
   
   SOLUTION: Added modifier classes like .search-page-style, .blog-page-style
