Add a Custom Logo for the Website

Currently, the website has "codeX" written as text in the header. I would like to replace this with a custom logo to make the website look more visually appealing and professional.

**Requirements:**

- Design a custom logo that represents the codeX100 brand.
- The logo should fit well in place of the current "codeX" text in the website header.
- Ensure the logo looks good on both desktop and mobile views (responsive design).
- The logo should be modern, simple, and aligned with the current color scheme of the website.
- Tools: Feel free to use any design tools (e.g., Figma, Adobe XD, Photoshop) to create the logo.

**Deliverable:**

- A high-quality logo in SVG or PNG format.
- The logo should be integrated into the website in place of the "codeX" text.
