TOC presented in left side when converted into HTML file

Usually, TOC is shown just below the page title or first section of the converted HTLML document.
However, when markdown is converted into HTML file, it's position in upper section decreases readability and it's hard to find specific topics in the document.

When TOC is presented on the left side of HTML document, it would be much better like outline plugin function in Joplin

This is possible in with exporting as 'Styled HTML with TOC'.

Is there any way of implementing this with any css or other plugin in Joplin?
