mam dziwny problem bo jak link był już odwiedzany, czyli visited to jak sie na niego najedzie to nie zmienia barwy!! co może być źle

a:link    { color: red }    /* unvisited links */
a:visited { color: blue }  /* visited links  */
a:hover  { color: yellow } /* user hovers    */
a:active  { color: lime }  /* active links    */

Note that the A:hover must be placed after the A:link and A:visited rules, since otherwise the cascading rules will hide the 'color' property of the A:hover rule. Similarly, because A:active is placed after A:hover, the active color (lime) will apply when the user both activates and hovers over the A element.
