My task involves transforming a website page along with all its external stylesheets into a single HTML file with inline CSS. This is not for usage in emails, but rather to incorporate styled sections of that page into another website's page. After some research, I came across the tool CssToInlineStyles, which effectively handles most of the conversion process. However, I still need to consolidate all the stylesheets into one file before passing it to the CSSToInlineStyles class.
