How to add icon when loading page ?

Hi there,

Sorry not sure what you mean...can you provide an example?

like this page http://hataraku.pw/. When you access this page you'll see the icon when the page is loading.

You'd have a find a plugin for that. Never used one before but maybe something like this: https://wordpress.org/plugins/popup-maker/

Thanks, Leo. :D

No problem!
