Disclaimer:
These solutions are based on my experience and best effort. Actual results may vary depending on your setup. Codes may need some tweaking.

1) Your landing page bounce rate is high. How would HTML structure alone help reduce bounce?

I’d audit headings to form a clear outline so users grasp content fast.
I’d add a meaningful <title> and meta description to set correct expectations.
I’d place primary CTA near the top with proper semantic grouping.
I’d ensure hero text isn’t hidden behind images and loads as real text.
I’d use landmark roles (<header>, <nav>, <main>, <footer>) for quick navigation.
I’d trim decorative HTML clutter so the first screen answers “what, why, how.”.

2) Lighthouse flags “Links do not have descriptive text.” How do you fix this purely in HTML?

I replace “Click here” with specific link text that sets destination context.
I avoid empty anchors and make icons have accessible text via aria-label.
I ensure surrounding text doesn’t carry meaning that the link itself lacks.
I keep one interactive element per link, not nested buttons.
I include visible focus states to show which link is active.
I remove duplicate links when one descriptive link suffices.

3) Stakeholder wants a “text-only mode.” What HTML choices support that quickly?

I use semantic elements so content stays meaningful without CSS.
I avoid images for headings; headings stay actual <h1- h6> text.
I add alt text to essential images so meaning survives.
I expose critical messages as plain text, not background images.
I ensure <details> can reveal summaries without styling.
I keep forms usable with native controls instead of custom divs.

4) Your page feels slow even after image compression. Which HTML decisions improve perceived speed?

I prioritize above-the-fold content order so HTML paints useful parts first.
I inline the critical hero copy as real text early in the DOM.
I defer non-essential iframes with loading="lazy" where appropriate.
I use decoding="async" for large images to avoid blocking render.
I place script tags low or use defer so HTML paints before JS runs.
I preconnect via <link rel="preconnect"> to speed initial fetches.

5) SEO team says Google reads titles poorly on some pages. What HTML pitfalls cause this?

Multiple <title> tags or titles generated after load can confuse crawlers.
Missing <h1> or inconsistent headings reduce page meaning.
Overuse of emojis/special characters can dilute keywords’ clarity.
Important text stored in images lacks searchable content.
Template reuse with identical titles creates duplication.
Titles too long or vague fail to communicate page purpose.

6) Your product cards render inconsistently across browsers. What HTML do you review first?

I check for unclosed tags and improper nesting that browsers autocorrect differently.
I verify unique IDs and avoid duplicate IDs across cards.
I confirm lists actually use <ul>/<ol>/<li> not random <div>s.
I ensure alt text is present and size attributes are consistent.
I use valid, minimal attributes to avoid quirky parsing.
I run HTML validation to catch structural errors early.

7) Designer wants a clickable container and inner button. Any HTML concerns?

Nesting interactive elements causes confusing focus and event order.
Screen readers may announce both, creating double interaction.
I’d keep one primary interactive element per region.
If the container must be clickable, inner element becomes static.
I use role="button" only when truly necessary.
I ensure keyboard users can activate exactly one target clearly.

I provide helpful placeholders without replacing labels.
I add input constraints (required, min, max, pattern) for instant feedback.
I simplify tab order so users move naturally through the form.

9) You must support screen readers well. Which HTML patterns are non-negotiable?

Alt text for informative images; empty alt for purely decorative ones.
Keyboard focus visible and predictable across interactive elements.
Avoid using <div>/<span> for controls that native elements cover.

10) Marketing demands auto-playing media on load. What’s your HTML-first stance?

Stacking dialogs can trap focus or hide content behind overlays.
Multiple interactive layers confuse screen readers.
Back navigation becomes inconsistent if content is dialog-only.
I’d propose pages or <details> for secondary info instead.
If modal is needed, one at a time with clear close controls.
The underlying page must remain inert while the modal is open.

I move text out of images and into the DOM.
I ensure figures with captions describe context, not restate.
I avoid ASCII art in alt that adds noise.

20) Your team uses custom components everywhere. What HTML principles keep them honest?

Each custom piece must map to a native role and behavior.
Keyboard interaction should match native expectations.
Labels, name, and value relationships must remain accessible.
Focus order and semantics must match the visual intent.

I load only necessary weights to cut payload.
I ensure key content is readable even before fonts load.
I avoid hiding text while fonts download.

I ensure the text is still selectable and readable in DOM.
I avoid fast or infinite scroll speeds that annoy readers.
I keep the important text visible in static fallback.
I highlight that users may disable animations in settings.

53) Your site uses nested forms. What HTML risks do you flag?

Nested forms are invalid HTML and break submissions.
Only the outer form submits, inner ones get ignored.
It confuses screen readers about which fields belong together.
I’d restructure into one form with grouped <fieldset>.
Or I’d separate into multiple independent forms.
Clear labels and consistent buttons keep intent obvious.

54) You must show progress in long operations. Which HTML approach?

I avoid hiding the input behind custom elements without labels.
I ensure error text exists for unsupported files.
I test on mobile since file pickers vary by device.

56) Your client pushes heavy inline styles. Any HTML trade-offs?

Inline styles bloat HTML and repeat rules everywhere.
They block caching, so every page reloads styles.
They’re harder for teams to maintain or override later.
Inline styles mix content and presentation, hurting readability.
I recommend semantic HTML with external CSS for clarity.
Reserve inline styles only for critical, one-off cases.

57) A page has multiple `<h1>`s. What’s the impact?

One <h1> is ideal for clarity, but HTML5 allows multiple.
Too many <h1>s can confuse screen readers’ outlines.
Search engines may dilute importance of the true title.
I’d keep one <h1> as page topic, use <h2–h6> for sections.
I validate heading order to form a logical hierarchy.
Consistency helps both accessibility and SEO.

58) You need to highlight code snippets. How to do it cleanly in HTML?

Wrap inline code in <code> for semantic meaning.
For blocks, use <pre><code> so spacing is preserved.
Avoid images of code, since they can’t be copied.
Add language hints for syntax highlighting if needed.
Ensure line breaks and spacing are kept accessible.
Keep contrast strong so text remains readable.

59) Your product description repeats same text in multiple places. What HTML risk is there?

Duplicate content may dilute SEO rankings.
It makes pages harder for readers to scan uniquely.
Repeated IDs or anchors can cause conflicts in DOM.
Screen readers may read redundant info unnecessarily.
I’d consolidate into one description and cross-link.
I ensure each section adds unique value.

60) A client insists on full-page image backgrounds. What’s your HTML view?

Large background images slow down initial paint.
Key content should never be inside those images.
I provide alt text only if image conveys meaning.
I compress and size them per device to cut weight.
I ensure text contrast stays readable over the image.
I offer fallback colors for cases where the image fails.
