Create a web page that generates a series of boxes, where the number of boxes is given by the user via a text input box. Incorporate the following behaviour: Set the background of each box to a random colour.

Number the boxes in consecutive integers, i.e. 1, 2, 3, . . . 1

Set the left margin of each box to be double the previous boxs left margin, where the first box has 5px left margin.

Clear the old boxes when a new input is given by the user. For reference, your code should produce something similar to the below figure for five boxes.

\begin{tabular}{ll} 5 & Draw \\ \hline \end{tabular} 1 3 5
