<span class=picon>app</span>

Mardown Integration

If you don't need the ~~strikeout~~ mardown feature you can create a rule to show striked text as icons:

del, s {
	font-family:picon; 
	text-decoration: none;
}

Live Demo

Composition

To stay lightweight, Picon does not provide any composed icons like call-in, call-out, call-forward.

Following the previous Mardown <del> example, you can compose using:

<style>
del {
	font-family: picon;
	word-spacing: -2em; /* Same size overlay */
	text-decoration: none; /* un-strike */
	text-shadow:/* white halo */
	-1px -1px 0 white,
	-1px -0px 0 white,
	-1px  1px 0 white,
	-0px -1px 0 white,
	-0px -0px 0 white,
	-0px  1px 0 white,
	 1px -1px 0 white,
	 1px -0px 0 white,
	 1px  1px 0 white;
}
del>sup,del>sub{
	font-size: .5em; /* twice smaller */
	margin-left: -1em; /* right side*/
}
del>sup{vertical-align:text-top;}
del>sub{vertical-align:text-bottom;}
</style>

Note: replace del with s or .picon according to your Mardown processor

you can now associate any parent with any child icon:

<del>microphone not</del>
<del>wifi4<sub>!</sub></del>
<del>printer<sub>magnifier</sub></del>
<del>bluetooth<sub>add</sub></del>
<del>gsm0<sub>chain</sub></del>
<del>wifi4<sub>5g</sub></del>
<del>lock<sub>warning</sub></del>
<del>file<sub>attachment</sub></del>
<del>calendar<sub>add</sub></del>
<del>battery<sub>bolt</sub></del>
<del>file<sub>markdown</sub></del>
<del>call<sup>rightward</sup></del>
<del>drive<sub>wrench</sub></del>
<del>screen<sub>colors</sub></del>
<del>picture<sub>contrast</sub></del>

HTML text element

As opposed to SVG, ligatured font can be used in text-only elements (<option>, <input> ...):

<input type=reset class=picon value=cross>

<select>
	<optgroup label=iconless>
		<option>wifi0
	</optgroup>
	<optgroup class=picon label="wifi0">
		<option>wifi0
		<option>wifi4
	</optgroup>
</select>

Pseudo-element

Font can react from states and attributes.

For example it can automatically display the corresponding language icon to a <pre> element:

<pre lang=js>
function example(){
	return 0;
}
</pre>

<style>
pre[lang]::before{
	font-family: picon;
	content: attr(lang);
	float: right;
}
</style>

Live Demo

It can also help to unify browser style for input typefile/checkbox/radio:

<input type=file data-before=file style=width:1em>
<input type=checkbox data-before=ballot data-before-checked=checked style=appearance:none>
<input type=radio data-before=false data-before-checked=true style=appearance:none>
<style>
[data-before]::before{
	font-family: picon;
	content: attr(data-before);
}
[data-before-checked]:checked::before{
	font-family: picon;
	content: attr(data-before-checked);
}
</style>

Color gradient

<style>
.rainbow{
	background: linear-gradient(
	#5eb544 00.0% 37.5%,
	#f5b226 37.5% 50.0%,
	#ed7e1e 50.0% 62.5%,
	#d9383c 62.5% 75.0%,
	#913b92 75.0% 87.5%,
	#0098d5 87.5% 100%);
	-webkit-background-clip: text;
	-webkit-text-fill-color: transparent;
}
<style>
<input type=search class="picon rainbow">
