I've heard that WebStorm (JetBrains IDE) provides a short writing syntax for html-grids. Something like div.class.class.class#id
but I can't find a documentation for that.
Could you give a short example?
It's called Emmet. WebStorm supports such abbreviation expansion.
WebStorm has own implementation and does not support all Emmet features/actions .. but abbreviation expansion is supported.
