Key improvements in this CSS:

Modernized Color Palette: Uses a more modern and visually appealing color scheme with shades of gray, blue, and green.
Improved Typography: Better font sizes, line height, and spacing for improved readability.
Enhanced Code Styling: More distinct styling for pre and code elements, including borders and better padding.
Refined Image Styling: Added a subtle box shadow and border-radius to images to make them stand out more.
Clearer Chat Sheet: Improved the styling of the chat sheet with a white background, subtle box shadow, and better spacing. Used flexbox for message alignment.
Responsive Design: Added a media query to make the layout more responsive on smaller screens (like mobile devices).
Comments: Added comments to explain different sections of the CSS.

How to use this CSS:

External Stylesheet (Recommended):

Save the CSS code as a .css file (e.g., style.css).
In your HTML file, link to the stylesheet in the <head> section:

<head>
    <link rel="stylesheet" href="style.css">
</head>

Internal Stylesheet:

Place the CSS code within <style> tags in the <head> section of your HTML file:

<head>
    <style>
        /* Paste the CSS code here */
    </style>
</head>

Using an external stylesheet (style.css) is the recommended approach because it keeps your HTML cleaner and allows you to reuse the same styles across multiple pages.
