Add telegram to social media icons

You can use the jetpack_social_media_icons_widget_array filter to add your own custom icon to the Social Media Icons Widget:

I hope this helps.

Well, it works, it shows next to facebook and twitter, but it seems I cannot display a telegram generic icon. Is there any way to add it?

I’m really grateful for your help.

That’s because the icon font used to display the other icons doesn’t include a Telegram icon. You’d have to add your own, or rely on another font that includes a Telegram icon on your site. For example, if you use Jetpack’s Sharing buttons on your site, your site already loads an icon font with a Telegram icon.

In the code snippet you used to add the Telegram icon, replace genericon genericon-telegram by social-logo social-logo__telegram, and then add the following CSS under Appearance > Customize > Additional CSS in your dashboard:

.widget_wpcom_social_media_icons_widget .social-logo__telegram {
	font-size: 16px;
    vertical-align: top;
    text-align: center;
    -moz-transition: color .1s ease-in 0;
    -webkit-transition: color .1s ease-in 0;
    display: inline-block;
    font-style: normal;
    font-weight: normal;
    font-variant: normal;
    line-height: 1;
    text-decoration: inherit;
    text-transform: none;
    -moz-osx-font-smoothing: grayscale;
    -webkit-font-smoothing: antialiased;
    speak: none;
}

That should help!

That did the trick! You are the boss!
