    Frequently Asked Questions
    What should I include when submitting content for HTML formatting?
    You should include the full article text, any image or video URLs you want to keep, and any structural notes such as headings, bullet points, or tables. The more complete the original content, the better the final formatted result.
    Will my original images and videos be preserved in the formatted HTML?
    Yes. All original images and videos will be retained with their correct aspect ratios. Images will be displayed with subtle shadows and borders for a polished look, and multiple images will be arranged in rows of two to three per line.

    Absolutely. The generated HTML uses responsive design principles, including flexible layouts and media queries, to ensure the content displays correctly on smartphones, tablets, and desktop screens.
    Will the HTML code conflict with my existing website styles?
