nav a versus nav a: link

I'm confused as to why Guil used nav a:link { text-decoration: none }

I simply used nav a and mine seemed to work just like his. Can someone explain to me why he used the link addition and when it'd be important to do it his way instead of mine?

Hey Victoria!

The :link selector specifically targets unvisited links! Upon first viewing the page (before you've clicked on any links) the page would appear the same. However, using Guil's method the CSS of the link could be different after it was visited whereas your method would have the link display the same regardless of if a user has click on it or not.

To break this down further:

a {
  /*This style applies to all of the links at ALL TIMES, regardless of status*/
}

a:link {
  /*This style applies ONLY to UNVISITED links*/
}

a:visited {
 /*This style applies ONLY to VISITED links*/
}

It's also important to note that due to the cascade, any pseudo-classes (:link, :visited, etc.) will over-rule a non-pseudo-class defined style. Meaning, if we were to use both of the methods like below:

a {
  color: black;
}

a:link {
  color: white;
}

The page would display the links as white and not black, because the pseudo-class is more specific.

Hope this helps!
