Answer

The CSS rule p { display: inline; } changes the display type of the <p> elements from block (which takes full width) to inline. This allows them to sit next to each other rather than stacking vertically.

Step 3

Re-write the line of code which will use a JavaScript event to call the function displayHelp when the image 'question.jpg' is clicked.

Step 4

Explain why the text is still not displayed when the function displayHelp is called.

Answer

The text is not displayed because the ID 'display' is not associated with any element in the HTML. The function is trying to access an element that does not exist.

Step 5

Re-write the line of HTML code to ensure that a reading has been entered for the electricity meter.
