Backend Blog U I - Copy this Html, Bootstrap Component to your project

I need a user interface for a Back End Developer's blog. The UI should be modern, elegant, and responsive, with the ability to toggle between light and dark modes. The key components should include: A header featuring the blog's name on the left and a dark/light mode switch on the right. A main section with a list of blog posts displayed in a card format. Each card should include a title, a brief description, and the date of the post. A sidebar that contains links to different technical categories like ‘Databases’, ‘REST APIs’, and ‘DevOps’. A footer with links to social media profiles and a brief author bio. The design should be implemented using Tailwind CSS or MUI and must look clean and professional. It should use a minimal color palette, with subtle highlights in neutral or soft blue tones to accentuate titles and buttons. The overall style should reflect the technical nature of the blog while maintaining a sleek, modern look.
