Topic on Extension talk:CookieWarning

Use the CSS provided. This is however not recommended.

What must i do? Thanks for help

Add the following in one of the stylesheets:

.mw-cookiewarning-container {
    top: auto;
    bottom: 0;
}

Thanks @Ciencia Al Poder for the answer :) @Evetro Please note, that the bottom is probably not prominent enough for the warning. It would also be possible for a user to click the links in the personal tools bar to e.g. create an account or login, which will potentially add more cookies to the users browser without having him read the cookie notice.
