Share your Discourse Christmas decorations!

Hi,

Here are some Christmas animated lights you can add under Discourse’s header.

This is an implementation of Toby’s Christmas Lights on Codepen: https://codepen.io/tobyj/pen/QjvEex
I tweaked the code a bit to make it fit Discourse.

See it in action here: https://forum.monocycle.info/ (I’ll remove them in January)

Screenshots:

On mobile (they will not follow the sticky header):

With a dark theme:

How to add it to Discourse:

  1. Go to your admin panel -> customization -> choose your current theme -> custom CSS/HTML
  2. Add this code in your CSS tab:

.mobile-view .lightrope {
    margin-top: -26px;
}
  1. Add this code in your After header tab:
<ul class="lightrope">
<li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li><li></li>
</ul>

(You may want to add some more <li></li> if you want your lights to take all the width of a 4K monitor. Currently, it fits a 2k monitor)

Save & Enjoy!

If you want to change the lights’ appearance, edit these variables at the beginning of the SCSS code:

$globe-width:   12px;
$globe-height:  15px;
$globe-spacing: 40px;
$globe-spread: 3px;
$light-off-opacity: 0.4;
$speed: 0.5;

The classic Santa claus hats on avatars:


Hat from uihere.com : G6gA3Wn

How to add it to Discourse:

  1. Go to your admin panel -> customization -> choose your current theme -> custom CSS/HTML
  2. Add this code in your CSS tab:
.main-avatar:after {
    content: url(https://i.imgur.com/G6gA3Wn.png);
    position: absolute;
    top: -5px;
    left: -19px;
}
.mobile-view .main-avatar:after {
    top: -17px;
}

(the hats should only appear on a topic view)

Save and enjoy your hats!

I recommend you to host the hat image on your Discourse server.
