Css animation SiteOrigin Button

Hi

To my site , http://www.toimerologio.me , i use SiteOrigin Button and it looks fine when i use css animation with the below code, to my css editor

.so-widget-sow-button-wire-8825c63bca5d .ow-button-base {
zoom: 1;
animation: pulse 2s ease infinite alternate;
}

but to an other page of my site , http://www.toimerologio.me/ferik%202/

it doesnt work .

Am i doing something wrong ?
