Add Section-Specific Styling for Enhanced Structure and Visual Appeal (…

…#419)

Issue Closed: #416

### Description

This PR addresses the styling issues for individual sections as
described in #416. Each section (Home, Upload, Features, Feedback, About
Me, Sign Up, and Contact) has been styled to create a cohesive theme and
enhance readability and user experience. Key improvements include
background colors, section spacing, text alignment, and image styling.

### Changes Made

- Styled each section with unique background colors and fonts to
maintain consistency with the website's theme.
- Added appropriate padding and spacing between sections to prevent
visual overlap and enhance clarity.
- Improved text and image styling to ensure readability, especially for
sections with dense content.
- Ensured content alignment within each section for a balanced and
visually appealing layout.

### Implementation Details

- Updated styles.css with new section-specific classes for each of the
seven sections.
- Applied unique background colors and font styles in line with the
theme of the website.
- Added spacing (padding and margin) to separate sections and avoid
blending.
- Styled images to ensure they are well-aligned with the text and scaled
appropriately across different screen sizes.
- Enhanced section borders and heading styles to make each section
easily distinguishable and visually appealing.

### Testing

- Verified that each section is properly styled and separated on mobile,
tablet, and desktop devices.
- Checked text readability and image alignment across all sections.
- Ensured each section's content remains visually balanced and
consistent with the overall design.
