ox-html: Include the line number as a data attribute
* lisp/ox-html.el (org-html-do-format-code): If line numbers are enabled then include a data-ox-html-linenr attribute that contains this line's line number. This allows you to have more control over line number formatting and placement. For example, the following CSS hides the span that contains the line number, and uses a CSS :before property to position and format the line number with a border instead of a semi-colon separating content and line number. span.linenr { display: none; } code[data-ox-html-linenr]:before { content: attr(data-ox-html-linenr); display: inline-block; border-right: 1px solid; width: 1rem; text-align: right; } TINYCHANGE
