This script causes every single character in passages to be wrapped in a <span class="char"> element. This enables a number of mildly interesting CSS effects.

Note: in some versions of Twine, this won't take effect in the Start passage!

Javascript code is as follows:

Wikifier.formatters.push({name:"char",match:".",handler:function(a){insertElement(a.output,"span",null,"char",a.matchText);
}});Wikifier.formatters.forEach(function(e){if(e.name=="prettyLink"){e.handler=function(a){var b=new RegExp(e.lookahead,"mg");
b.lastIndex=a.matchStart;var c=b.exec(a.source);if(c&&c.index==a.matchStart&&c[2]){var d=Wikifier.createInternalLink(a.output,c[1]);
setPageElement(d,null,c[1]);a.nextMatch+=c[1].length+2;}else{if(c&&c.index==a.matchStart&&c[3]){var f;
if(tale.has(c[4])){f=Wikifier.createInternalLink(a.output,c[4]);
}else{f=Wikifier.createExternalLink(a.output,c[4]);}setPageElement(f,null,c[1]);
a.nextMatch=c.index+c[0].length;}}};}});

These characters have the class of "char", and also a class equal to themselves ("a" for the letter "a", "2" for "2", etc.) It's recommended that you use the :nth-child pseudo-class to select them. Some potential CSS effects that can be performed include the following (examples only):

Wavy text:

 .char{ position:relative; }
.char:nth-child(8n) { top:0px; }
.char:nth-child(8n+1) { top:-1px; }
.char:nth-child(8n+2) { top:-1.5px; }
.char:nth-child(8n+3) { top:-1px; }
.char:nth-child(8n+4) { top:-0px; }
.char:nth-child(8n+5) { top: 1px; }
.char:nth-child(8n+6) { top: 1.5px; }
.char:nth-child(8n+7) { top: 1px; }

Rapid rainbow text:

.char:nth-child(8n) { color:hsl(45,100%,75%); }
.char:nth-child(8n+1) {color:hsl(90,100%,75%); }
.char:nth-child(8n+2) {color:hsl(135,100%,75%); }
.char:nth-child(8n+3) {color:hsl(180,100%,75%); }
.char:nth-child(8n+4) {color:hsl(225,100%,75%); }
.char:nth-child(8n+5) {color:hsl(270,100%,75%); }
.char:nth-child(8n+6) {color:hsl(315,100%,75%); }
.char:nth-child(8n+7) {color:hsl(0,100%,75%); }

Remove all the T's in the passage text:

.char.t {
  display:none;
}

Change "u" to "U":

.char.u {
  visibility:hidden;
}
.char.u::before {
  content: "U";
  position:absolute;
  visibility:visible;
}

These are to be considered basic examples - prompts for more practical uses.

This code also enables some particularly interesting Javascript visual effects to be performed, which I shall explore in a future blog post.
