Seeing Your Page Live
Your page is built. Now you preview it, which means opening it to see how it really looks.
Most AI coding tools show a live preview, or you can open the HTML file in a browser. Seeing the real page reveals things that prompts alone cannot.
Look Like a Visitor
When you preview, pretend you are a first-time visitor. Scroll slowly from top to bottom.
Ask yourself: Do I understand what this is in five seconds? Is the button easy to find? This honest look guides your next tweaks.
Spotting Small Problems
Previews often reveal tiny issues: text too close to an edge, a button that blends in, or a heading that is too big.
These are normal. Note what bothers you, then describe each fix to the AI in plain words.
The headline is too close to the top edge of the page.
Add some space above it so it does not touch the edge.Tweaking One Detail
Tweaking means making small, focused changes. You are polishing, not rebuilding.
Change one detail, preview again, then decide if you like it. This loop of tweak and preview is the heart of finishing a page.
Make the "Get Started" button a little bigger and add more space around it so it is easier to tap.Check It on Mobile
Many visitors arrive on phones. A page that looks great on a laptop can feel cramped on a small screen.
Ask the AI to make the page responsive, meaning it adjusts to fit phones, tablets, and computers nicely.
Make the page responsive so it looks good on phones.
Stack the feature cards in a single column on small screens and keep the text readable.Test the Button
The main button is the point of the page. Click it in the preview to see what happens.
If it should open a sign-up form or another page, tell the AI where it should go. A button that does nothing confuses visitors.
Make the "Get Started" button scroll smoothly down to the final call-to-action section when clicked.Fix Wording on the Spot
Seeing words in context often reveals awkward phrasing. A line that read fine in a prompt may feel clunky on the live page.
Just quote the text and ask for a smoother version. Small wording tweaks make a page feel professional.
Change the subtitle from "App that reminds plants" to something smoother and clearer, like a friendly one-line promise.Trust Your Eyes
If something looks off but you cannot name why, say exactly that. The AI can suggest options to try.
You can ask "Why does this hero feel empty?" and get ideas. Your eyes are a good judge, even without technical words.
The hero section feels empty and unbalanced.
Suggest two or three ways to make it look more complete and balanced.Avoid Over-Tweaking
It is easy to keep changing things forever. At some point, the page is good enough.
Make the changes that clearly help, then stop. Endless tweaking can break a page that was already working well.
Final Polish Pass
For your last pass, ask the AI for a gentle review. It can catch spacing gaps, mismatched colors, or a missing alt text on images.
This final check helps your page feel finished and trustworthy before you share it.
Do a final polish pass on the PlantPal page.
Fix any spacing issues, make colors consistent, and check that the page looks clean on both phone and desktop.You Built a Landing Page
You started with nothing and, using only plain-language prompts, built a styled landing page with real sections and a working button.
You scaffolded the bones, styled the look, added content, and polished it through preview and tweak loops. That is vibe coding in action.

Recap: Previewing and Tweaking
You learned to preview your page like a real visitor, spot small problems, and fix them one tweak at a time.
You made the page mobile-friendly, tested the button, polished the wording, and avoided over-tweaking. You can now build and finish a landing page entirely by prompt. Well done.
