HTML tags turn 35

On October 29, 1991, Tim Berners-Lee, one of the founders of the World Wide Web, published a document called HTML Tags.

The document described the first 18 HTML tags: <title>, <nextid>, <a>, <isindex>, <plaintext>, <listing>, <p>, <h1> and other headings, <address>, <hp1> and other emphasis tags, <dl>, <dt>, <dd>, <ul>, <li>, <menu> and <dir>.

It was from these simple elements that the history of the markup language began, on which practically the entire internet is built today.
