This is not possible out of the box. You might use some Babel code to
generate the needed HTML but I guess it wouldn't be particularly easy.

Nevertheless, there's a solution. `html' back-end can redefine what
a paragraph is, instead of following Org's own definition. More
explicitly, an HTML paragraph can be defined as a cluster of elements
not separated by any blank line and containing at least an Org
paragraph. Hence:

  #+attr_html: :width 10%
  #+attr_html: :width 10%

consists of two paragraphs in Org, but would be seen as a single
paragraph by HTML, and exported as such.

Implementation is simple using pseudo-elements. `latex' back-ends does
it already for tables and math snippets. However, I'm no HTML
specialist, so there may be drawbacks I cannot foresee.
