I'm new to the webdevelpment and I want to know whether HubSpot supports W3.CSS and Bootstrap 4. If not what is the best practice to create responsive website.
sure, you just need to embed the w3.css or the bootstrap4 files to your page / template (however you like).
If you have embeded the files, you can use the respective classes to create a responsive page.
HubSpot uses as default - Bootstrap 2 and jQuery 1.7x or 1.11.x
You might want to upgrade the jQuery aswell, you can to that in Setting -> Website -> Pages under jQuery, you can exclude the default one and embed your own, like other js files
