These snippets include some element of HTML, whether it be vanilla CSS, or exensions like SASS/SCSS and (for older sites) LESS.
They have been organized in terms of the version of Bootstrap that they were originally built for. Some snippets are fully backwards- and forwards-compatible with other versions of Bootstrap, but others will need changes. If you feel that a snippet is included in the wrong section, you can edit this page to move it, then create a merge request with your example site / reasoning in a comment.
