Problem with Pagination / CSS not showing in Chrome

Hello,

I've taken over to maintain a site for someone that uses an old JEvent.
I need to upgrade his page anyway but before we can it will take some time.

I would like to solve some issues until then.

one is with JEvents:

Like in that post (https://www.jevents.net/discussions/solved-pagination-problem) we had vertical pagination.
So I changed the templates "template.css" and added:

/*** Pagination ***/

div.list-footer {

    margin: 10px 0 0 0;

    padding: 10px 0 0 0;

    text-align: center;

}



div.list-footer ul {

    list-style-type: none;

    margin: 0;

    padding: 0;

}



div.list-footer li {

    display: inline-block;

    padding: 2px 5px;

    border: solid 0px #eee;

    margin: 0 2px;

    background: none;

}



div.list-footer li.pagination-start li.pagination-next li.pagination-end li.pagination-prev span.pagenav a.pagenav {

    border: 0;

	padding: 0;

	 float: left;

}

This works well in Microsoft Edge but in Crome I still see the certical pagination and none of the changed values are visible.
I had this before when I tried on other css things. Always only visible in other browsers than chrome.

Any Idea?
