Update Home.module.css

[surabhigupta071]

Here's a list of the changes I've made:

• Added a box-sizing rule to the .container class to improve layout consistency.
• Changed the padding value in the .main class to use 2rem instead of 4rem for a more balanced look.
• Removed the min-height property from .main as it wasn't necessary.
• Simplified the flex-grow property in the .footer a selector to use 1 instead of flex-grow: 1.
• Updated the text-decoration property in .title a:hover, .title a:focus, and .title a:active to only apply an underline instead of other decoration styles.
• Changed the font-size value in .title from 4rem to 3rem to improve readability.
• Removed the line-height property from .description as it wasn't necessary.
• Added a box-shadow property to the .card class to give the cards a subtle drop shadow effect.

These changes should improve the overall design and readability of the page.
