<1b> The static html template is given. Please transfer the pdf document to the html template. Keep the same format, including font size, line height etc the same. You may need to write some new code to the existing template.
<2> For the left panel, make an expandable index similar to the idea shown in the picture. The idea is to guide the user efficiently.
