"Buy our E-book" button is not visible in night mode

[megh-bari]

Description:

• Problem: When switching to night mode, the "Buy our E-book" button is not visible or disappears from the page.
• Expected Behavior: The "Buy our E-book" button should be clearly visible and accessible in both day and night modes, with appropriate styling for night mode.
• Actual Behavior: The button is either not rendered or has a color/style issue that makes it blend into the background in night mode, making it appear as if it's not present.
