If you can compile elinks from source, the following patch (against
current git master) would do it. This adds toggle-margin action
(default keybind "M") to toggle the margin between 0 and the specified
margin_width (which can be up to 100 now).
It also adds document.browse.use_margin option to specify whether
margins are to be used at startup.
There is currently no check for too large of a margin. Strange things
may happen if 2*margin > #columns.
