javascript - Icons in HTML and CSS as a code (eg: ) -


i participate on project displayed icons this:

<span class="streamline" aria-hidden="true" data-icon="&#xe006;">some label</span>

the project in ruby on rails, thought icons saved in /assets folder, they're not there.

in css files, see this:

.streamline[data-icon]:after, .filtericons[data-icon]:before, .slicons {   font-family: 'streamline';   content: attr(data-icon);   speak: none;   font-weight: normal;   font-variant: normal;   text-transform: none;   line-height: 1;   margin: 0 5% 0 0;   -webkit-font-smoothing: antialiased;   -moz-osx-font-smoothing: grayscale; }

how icons works? need add new icon, not sure @ how system of displaying icons working - it's thing of css?

thank you

the data-icon referencing character within icon font streamline. @ top of stylesheet:

@font-face {     font-family: streamline;     src: url( /* url .eot file */ ) format("embedded-opentype"),          url( /* url .woff file */ ) format("woff"),          url( /* url .tff file */ ) format("truetype"),          url( /* url .svg file */ ) format("svg");     font-style: normal;     font-weight:normal; }

that css defines font-family streamline. url's font files show they're located.

if want see icons available in font, can download .tff file , try this:

myfonts - how see characters in font?

to use different icon exists in font you're using, need change data-icon attribute corresponding html entity (&#*****;). code, copy character font want use, , paste 'decoded' box on page:

html entity encoder/decoder

to use icons don't exist in streamline need replace font files new ones include characters want.
