Created an interactive blank filling worksheet with blank-boxes darken when clicked - with POE app creator

 The last attempt made use of lines for the blank filling: Ss click on the line (a blank), and then click on a word in the Word Bank. The word in Word Bank will appear in the blank. 

But: (1) it may not be easy for Ss to click on a line, and (2) when a line is clicked, there is not a clear sign that the line has been clicked. Hence when Ss have found their intended word in the Word Bank, and go back to the previous line blank, they may miss it. 

This time, after a couple of prompt revisions, I obtained the following interactive page. This time, when a box (instead of a line) is clicked, it darkens. That makes it easy for Ss to recognise which is the blank in question.
