We need to produce a concise 450-500 word WordPress blog post in HTML format. Title must be SEO-friendly, include “AI” and “ai”. Use plain HTML paragraphs and headings, using WordPress block comment syntax? They gave example:

…

. So we need to output HTML with those comments for each paragraph and heading? They said “write as plain HTML paragraphs and headings (e.g.,

…

)”. So we need to use that format for each paragraph and heading. Likely headings also have block comments:

…

. We’ll follow that. We need to start with title as a plain heading (e.g., “Title: …\n\n”), then HTML content. So first line: Title: … then blank line, then the HTML content. We must count words 450-500 inclusive. Must be concise but that many words. Let’s aim for ~470 words. We need to incorporate facts from e-book. Provide actionable content. Use the facts. We need to end with a paragraph promoting the e-book with link as given. We must not use placeholders. Write complete content. We must not include any thinking process. Let’s craft. First, title: SEO-friendly include “AI” and “ai”. Something like: “AI-Powered Tips for ai Assisted eBook Formatting: Achieving ePub Excellence Across Devices”. Ensure both AI and ai appear. Title line: Title: AI-Powered Tips for ai Assisted eBook Formatting: Achieving ePub Excellence Across Devices Now content. We’ll need paragraphs and headings. Let’s outline: – Introduction paragraph – Heading: Start with Semantic HTML and Mobile-First CSS – Paragraph about CSS reset, rem units – Heading: Convert DOCX to ePub3 – Paragraph about semantic HTML, mobile-first CSS – Heading: Image Handling – Paragraph about max-width, figure, figcaption, alt text – Heading: Avoid Background Reliance – Paragraph about backgrounds stripped – Heading: Test Reflow Across Devices – Paragraph about changing font size, family, rotate screen – Heading: Use Good CSS Practices – Paragraph about good vs bad examples – Heading: Navigation and TOC Validation – Paragraph about NCX/nav matching heading styles, test links – Heading: Internal Links and Back Button – Paragraph about testing cross-references, endnotes, back button – Heading: Avoid Floats Issues – Paragraph about floated image problem, solution – Heading: Use Reedsy Studio Preview – Paragraph about instant preview – Heading: Drop Caps and First-Letter Styling – Paragraph about ::first-letter pseudo-element – Heading: Manual Formatting Pitfalls – Paragraph about avoiding tabs, spaces, text boxes – Heading: Testing on Devices – Paragraph about Kobo, Nook, Apple Books, Kindle via Send to Kindle – Heading: Final Validation Checklist – Paragraph summarizing checklist items – Promotion paragraph (as required) We need to ensure word count 450-500. Let’s write and then count. We’ll need to include the block comments for each paragraph and heading. We’ll do:

Title

? But they said start with title as plain heading (e.g., “Title: …\n\n”), then HTML content. So title line is plain text not HTML block. Then after that we start HTML content with block comments. Thus output:

…

… Make sure no extra explanatory text. Now craft paragraphs. Let’s write content and then count words. I’ll write in a text editor mentally, then count. I’ll start: Title: AI-Powered Tips for ai Assisted eBook Formatting: Achieving ePub Excellence Across Devices

Self‑publishers who leverage AI tools can streamline ePub production, but the output must still meet strict reflowability standards to look great on every device.

Start with a Clean Semantic Foundation

Apply a CSS reset that normalizes margins and uses rem units for scalable spacing. This foundation lets the layout adapt when readers change font size or orientation.

Convert DOCX to ePub3 with Mobile‑First CSS

Export your manuscript as clean HTML, then package it into an ePub3 file. Write mobile‑first CSS that defines base styles for narrow screens and adds media‑only rules for tablets and desktops.

Handle Images Responsively

Ensure every image has max-width: 100% and is wrapped in a <figure> element with a descriptive <figcaption>. Insert meaningful alt text in Word so it carries over to the ePub.

Do Not Rely on Backgrounds or Borders

Many reading systems strip background colors or images; therefore, never convey essential information through them alone. Use contrasting text colors or icons instead.

Test Reflow Under Real‑World Conditions

Change the font size, switch the font family, and rotate the screen. If the text remains beautiful and readable, your stylesheet is truly fluid.

Adopt Good CSS Patterns

Use font-size: 1rem; margin-left: 2em; for paragraphs. Avoid hard‑coded values like font-size: 12pt; margin-left: 50px; that break when users adjust settings.

Validate Navigation and TOC

Check that the NCX or nav.xhtml document exactly mirrors your Heading 1‑3 hierarchy. Click every link in the table of contents to confirm it jumps to the correct location.

Test Internal Links and Back Button

Verify all cross‑references (“See Chapter 5”), endnotes, and the “Back” button work after following a link. Broken navigation frustrates readers and hurts reviews.

Avoid Problematic Floats

A floated image placed at the bottom of a chapter can cause the next chapter heading to wrap awkwardly around it. Instead, let images flow naturally or use clearfix techniques.

Leverage Reedsy Studio for Instant Preview

Reedsy Studio’s built‑in preview lets you see reflow changes in real time, catching layout issues before you export the final ePub.

Style Drop Caps Correctly

If you use drop caps or special first‑letter styling, implement them with the ::first-letter pseudo‑element. This prevents unwanted indentation shifts in the surrounding text.

Eliminate Manual Formatting Artifacts

Do not use manual tabs, spaces for indentation, or text boxes. Let HTML tags and CSS handle all spacing to keep the file clean and device‑agnostic.

Test on Multiple E‑Readers

Open the ePub in Apple Books on iPhone/iPad, preview it in a Kobo or Nook app, and send the final file to your Kindle via “Send to Kindle” email or USB. Spot‑check each device for consistent reflow.

Final Quick‑Check Checklist

Before publishing, confirm: CSS reset with rem units; images max‑width 100% inside figure/figcaption; alt text present; no background‑only info; good vs bad CSS patterns; TOC matches heading hierarchy; all internal links and back button work; no problematic floats; drop caps use ::first‑letter; no manual tabs/spaces; tested on Apple Books, Kobo/Nook, Kindle.

Now the promotion paragraph exactly as required:

Now we need to count words. We must count words in the entire output after the title line? The instruction: article must be between 450-500 words. Likely includes everything after title? Usually the whole article content (excluding title line?). Safer to count everything after the title line (the HTML content). But we can include title line in count? Safer to count everything after title line, but we can also count title line as part; still need to be within range. Let’s count words of the HTML content (excluding the title line and the initial blank line). We’ll count manually. I’ll copy the content into a counting method mentally. I’ll write each paragraph’s text and count. Better: I’ll approximate then adjust. Let’s list each paragraph’s textual content (excluding HTML tags and code snippets? Words inside code counts as words? Typically yes, but we can treat them as words. We’ll count everything visible. I’ll go paragraph by paragraph. 1. Introduction paragraph: “Self‑publishers who leverage AI tools can streamline ePub production, but the output must still meet strict reflowability standards to look great on every device.” Count words: Self‑publishers(1) who2 leverage3 AI4 tools5 can6 streamline7 ePub8 production,9 but10 the11 output12 must13 still14 meet15 strict16 reflowability17 standards18 to19 look20 great21 on22 every23 device24. => 24 words. 2.
