.goog-te-banner-frame.skiptranslate {
    display: none !important;
}
body {
    top: 0px !important;
}

for some browser this command stil doesnt work, so you should another command, and it would be like this :

iframe.skiptranslate {
    visibility: hidden !important;
}

.goog-te-banner-frame.skiptranslate {
    display: none !important;
}
body {
    top: 0px !important;
}
