What problems would this solve? =============================== Sometimes MDN authors have tangential content that is longer than a "callout", but not big enough to be a separate article, or is best viewed along with the main article. The "aside" element is appropriate for this type of content. In the context of MDN, it makes sense to format asides as sidebars. An example of where this could be applied (which currently uses table layout): https://developer.mozilla.org/en-US/docs/L20n#What_L20n_looks_like Who would use this? =================== MDN authors would use it, though hopefully sparingly. What would users see? ===================== The aside content could be floated right, with some padding and space, and maybe a border or background difference to set it apart from the main text. If the viewport is too narrow for multiple text columns, the aside could appear in the main flow, but with the same border/background difference. What would users do? What would happen as a result? =================================================== MDN authors could fully use the capabilities of HTML5, and would not have to resort to table layout. Is there anything else we should know? ====================================== If there might be other uses for asides, this could be done with a class such as <aside class="sidebar">.
