An editor preview is not the whole test
1 · Learn
A page can look correct in an editor but fail after export or publication because links, paths or media are missing. Test the actual permitted viewing copy, including every navigation link and important action.
Check a narrow screen and keyboard navigation as well as a wide screen. Keep publication under adult control; a classroom draft does not need to become a public website to demonstrate page design.
2 · Worked example
I discover a Models link points to an editor-only location. I replace it with the correct relative destination in the private project and retest from the home page.
3 · Your turn
Does a screenshot prove that a page's links work?
Check your answer
No. It shows appearance at one moment, not successful navigation or interaction.
4 · Apply your learning
Use a checklist to test a private three-page project, recording the action, expected result and actual result.
Adult guidance and safety
Use a school-approved offline or supervised tool and fictional data. Keep work private, respect media permissions and check accessibility. Paper traces support understanding but do not replace running, saving and testing a real project. Do not enter passwords, addresses or other personal details into exercises.
Open your writing and drawing pad
Write, draw or show your working. Use a mouse, pen or finger. This pad is not a submitted answer.
Not saved to your account. Download your drawing as PNG and your typed notes as TXT before leaving or refreshing. They are separate files. Do not enter private information.
Open a picture saved on this device to draw on it again. Opening replaces the drawing, but Undo can restore it. PNG only, up to 4 MB and 4096 × 4096 pixels. The picture stays in this browser; it is not uploaded. Paper lines in a saved picture become part of that picture.
Clear the drawing? Your typed notes will stay. You can undo this action.
Your pad is empty.
Open a UTF-8 TXT file from this device, up to 40 KB and 10,000 characters. It stays in this browser. Opening can be undone until you type again. Downloads keep a new copy; they do not change the file you opened.
Replace the notes on this page with the opened file? Download the current notes first if you want to keep them.
Typed notes are not submitted answers.
Check a calculation · Year 5 onward
Use this only when your teacher or adult allows a calculator for the task. Show your thinking first. It does not replace mental or written arithmetic and does not mark your lesson answer.
