Link in .site-footer area


i want to add a link to the buttom of all of my pages in my .site-footer area.

Right now i use additional css to disable the presented by wordpress text with this snippets:

    .site-info.container {
        display: none;

    .site-footer {
        background-color: #d65050;

I read some other topics about changing the footer.php but i guess this will conflict with my css.

thank you in advance

Hello, please check this topic:

Please feel free to ask any other questions that you might have.

I’ve read the topic.
However I thought my additional CSS display: none will prevent the text to be displayed.

Am I wrong?
