The art of CSS and its intricate selectors

There are 6 unique types of selectors in CSS style rules: type, universal, ID, class, pseudo-class, and descendant. Can you identify and name the four different selectors used in these style rules? 

#a1, .important { font-style:italic } 
ol span { background-color:aqua } 
a:hover { color:green }

I found the information on this website. http://www.w3.org/TR/CSS21/selector.html#simple-selector

The only selector I can guess is that #a1 is a universal selector?

Can someone please explain this to me? Or direct me to a website that can guide me through this concept better as w3 wasn't helpful.

Answer №2

The initial selector combines the ID "a1" with the class ".important", targeting specific elements. The second selector targets all spans that are grandchildren of an ordered list using descendant selection. Lastly, the third selector applies to all anchor tags in a hover state using the universal selector.

Answer №3

#a1  - Selects elements with the ID "a1"
.important    - Applies styles to all elements with the class "important"
ol span  -  Targets all <span> elements within an <ol> element
a:hover - Styles applied when a link is hovered over
