Po najechaniu napisu na stopce, tenże napis przesuwa się nieco w dół

Witam.

Na samym dole strony mam stopkę i na jej środku widnieje napis. Gdy przejadę lewym przyciskiem na ten napis, to tenże napis przesuwa się nieco w dół. Bez sensu.

Na podstronie pierwszej i drugiej mam taką samą stopkę i zapis w CSS jest tam dokładnie taki sam. I wtedy tenże napis na stopce nie przesuwa się już w dół.

Wiecie co jest przyczyną, że na stronie głównej w stopce ten napis przesuwa się nieco w dół?
