6,183 PointsRight at the end of the video you can see that the 'color: white' bit got ignored after he deleted 'a'. Wondering why.
I'm an absolute noob at this stuff, so if someone answers this, please do so with this in mind! Thanks.
Just to clarify, this is at the end of the video when he is showing the ':focus' pseudo-class. When it was written 'a:focus' the text showed up as white with an orange background, but once he deleted the 'a' in the beginning then the orange background still showed up, but the text stayed lightblue. Just wondering why!
Thanks again if anyone takes the time to clear up my doubts :)

231,007 PointsThe selector "a:focus" means "an anchor element (link) that has focus", but just ":focus" by itself means "any element that has focus". So there won't be any change to "a" elements, but now the rule will cover other input elements (if there are any) when they have focus.
The other thing that happens is the rule now has lower specificity. A rule that targets both a tag and a class is considered more important that one that targets only a class. So while this rule previously superseded the color set by other CSS rules, without the "a" it does not.
For more details, see the MDN page on Specificity.
