If you read editorial after solving one of the archived problems and don't want to spoil unsolved ones, you might find this custom javascript extension snippet useful:
$(function() {
if ($("a.tag:contains('editorial'),a.tag:contains('tutorial')").length === 0) return;
$(".content h2, .content h3").each(function(a,b) {
var <span class="tex-span"><i>h</i> = </span>(b);
var $t = $h.nextUntil('h2, h3');
$h.after("<a href='#' class='show-spoiler'>show</a>");
var $l = $h.next('.show-spoiler');
$l.click(function() {
$t.css('visibility', 'visible');
$l.remove();
return false;
});
$t.css('visibility', 'hidden');
});
})
I have not tested it on each and every editorial ^_^ upd1: fixed issue with picking 'editorial' links from new's block
Cool! I also did something like this some time ago: Unspoil. It's just a simple bookmarklet, so it should work on more browsers, and doesn't need any extensions. :)
(All the heavy work is being done by spoiler alert, so credits goes to them)
nice one! added to bookmarks :) thank you!
