How to remove the "topics _per week_" count?

Here’s what I did:

th.topics, td.topics {
    display: none;
}

Ok, so I am new to the discourse world and I have not so much clue about CSS. So could you maybe explain a bit where did you put this in or what one have to do to switch from the topic per week to the amount of posts.

Thanks in advance.
