Even Tabber is not a recommended practice.

"When the Tabber extension was developed many years ago, we did not anticipate changes to the web would make it a less than ideal choice for content. We now know that there are several issues that go along with using tabbers in articles, and we do not feel they are a great solution overall. As we've mentioned before, the usability of tabbers can be very tricky and most readers tend to ignore everything on tabs after the initial one. We have done tracking studies to verify this, and always get consistent results. At best, the use of tabbers should follow the 12 design guidelines listed by the Nielsen-Norman Group. In practice, there are many communities that use tabbers properly. On the other hand, there are impacts to search engines (including recent changes by Google in how their algorithm and crawling engine work). Tabbers function by obscuring or cloaking content. Hiding content inside secondary tabs signals to Google that you don't value it; they would rather a user to be able to search something - click a result - and get their answer. If you have competition for the same information and another site satisfies Google's user, Google will begin to favor the site with more immediately visually obvious results. We strongly suggest moving to a model described in the paragraph above (linked subpages) if you feel pages are too long, rather than using tabbers to reduce the article size. We strongly suggest not using tabbers at all unless necessary, and to find alternatives where possible that are more aligned with the way the web works today."
