Practice project: Harbor Home Care01 / GET READY
Before you start.
- Platform / editor
- HTML, CSS and JavaScript; Python local preview server
- Access & plan
- Text editor, modern browser and Python for local preview. Hosting and form-backend accounts are needed only for their corresponding lessons.
- Starting point
- Complete the previous lesson or use an equivalent prepared demo project.
Keep a note of the exact account, project and version you use. Work with demo data and record the expected result before making changes. Never place passwords, verification codes or private customer records in your evidence.

Open the official walkthrough.
Use the publisher's instructions and available screenshots to locate the current controls. Then return here for the SETLY exercise and its result checks. These links open on the publisher's website.
Source credit belongs to the named publisher. These are external references, not SETLY recordings or a claim of affiliation. Screen names and plan availability can change.
03 / PUT IT INTO PRACTICE
Your task, step by step.
Use one labelled demo record or project so you can find your work again. Finish each action before continuing; if the screen differs, consult the matching official source rather than guessing.
- 01
Step 1
Check the actual rendered width of the image area. Export a suitably sized copy in a browser-supported format and keep the source file.
- 02
Step 2
Set width and height attributes so the browser can reserve space. Write alt text for the information conveyed by the image.
- 03
Step 3
For below-the-fold images, consider loading=lazy. Keep the main visible image promptly loadable and avoid downloading an unnecessarily huge original.
- 04
Step 4
Compare page loading with a throttled connection and inspect the image on a high-density screen. Record dimensions, file size and visible quality.
04 / GET UNSTUCK
If something goes wrong.
Start with the likely cause
If the image is stretched, restore its aspect ratio. If it becomes blurry, increase dimensions before increasing compression quality blindly.
My screen is different from the guide
Check the product, editor, account role and selected project first. Open the credited official instructions for your version. Record the difference and pause any action whose effect you cannot verify.
The screen looks correct, but the result is missing
Inspect the saved record, published page or execution log that should prove the action. A preview, success message or draft is not always evidence that data was stored or a message was delivered. Retest with one unique demo value.
05 / PROVE THE RESULT
Check it before you call it done.
The image remains clear at its intended size and does not cause a large layout jump while loading.
Keep useful evidence
Record the test date, project/version, expected result, observed result and a non-sensitive screenshot or record reference. Mark anything you did not test as untested. Your checkmarks do not certify an untested result.
