Issue Description :
I propose updating the UI for the Features Page and Get Started Page to improve usability and aesthetics:

• Modernize the layout with better spacing, alignment, and responsive design.
• Enhance typography and color scheme for a consistent and engaging look.
• Add interactive elements (hover effects, transitions) for better user engagement.
