I need to extract the texts from a site and save it to pdf

Description

I need to extract the texts from a site and save it to pdf, I need to get all the legal reports from 'https://www.lawlanka.com/', and all the text documents to a PDF with the same format and folder structure.
For example, on the above website, there is a section named 'Case Law' in the navigation bar. You can find different case laws there like New Law Reports and Sri Lankan Law Reports. If you go to the New Law Reports, you can find all available volumes in the right sidebar. If you select one volume from there, all the individual reports will be opened in the main window.
What I need is, you should get all those individual reports and save it as PDF with certain formats, like change the font to Times New Roman with 12 font size.
