codegenweb/Hannah-Personal-Portfolio — reverse-engineered prompt

Build me a simple but polished personal portfolio website for someone named Hannah, using just HTML and CSS. I want it to feel clean, modern, and professional, with a nice visual landing section, a short about me area, a place to show a few projects or pieces of work, and an easy way for people to contact her. If there is a background image available, use it in a tasteful way so the page feels more personal without getting busy.

Please make it a single page site that looks good on both desktop and mobile. Keep the layout easy to scan, use readable text, smooth section spacing, and colors that feel elegant and friendly. Add basic portfolio content with placeholder text where needed so the page looks complete out of the box. I do not need anything complicated or app like, just a strong portfolio homepage that someone could quickly customize with their own info and links. If you need inspiration for current portfolio styles, feel free to look up a few examples online.
