Question

I use something like this: 1,40 fo but I think is not the most efficient way.

What’s yours?

Answer 1

I use foldmethod=marker and have mappings to enter <!-- {{{ --> and <!-- }}} --> where I want the fold to start and end. I put the start marker on the line with the opening block tag like:

<div id="topmenu"> <!-- {{{ -->

so when it’s folded I immediately see what the fold contains without the need to add extra comment.

For CSS it’s even easier, I just use foldmarker={,} and all definitions are automagically folded showing me just a very clear list of all classes, tags and ids which I can open just when I need them. Actually all my CSS files have this line at the very end:

/* vim: set fdm=marker fmr={,}: */

You can also visually select the region you want to fold and press zf if you prefer.
