Text Not Visible in Home Section on Responsive View Due to Background

In the home section of the website, when viewed on responsive screens (mobile or tablet), the text becomes hard to read or completely invisible due to the background image or color. This affects the readability and overall user experience.

Start at the home section in the HTML and inspect its responsive CSS rules and background declarations. Reproduce the issue at mobile and tablet widths, then verify that the home text remains visible and readable against the background in both viewport sizes.
