HI @seonathankk !

I would suggest resetting the lesson.

Your task is to select all but the last fieldset element.

You will need to first read about the not pseudo class

Then you will need to read about the last of type css pseudo class

Hope that helps!

i will take a look thank you!

thank you for replying! why does it see the last input element as a sibling? wouldn’t the fieldset:last-child just look for the last fieldset element? does a submit button count as its own fieldset?

thank you for your time! I now understand :blush:
it was trying to find a fieldset element which also has to be last sibling of the parent (form) but since input was the last sibling it didnt work.

Let me clarify one thing. The fieldset:last-child selector ignores the 3rd fieldset because it is not the last sibling and a fieldset element.

The use of last-of-type basically filters out all the other siblings and then looks at the last of the same type.

For example, if I had the following:


<div id="one">

<div id="second">
    text in div


p:last-child {
  background: green;

the only background that turns green is for the p with c as its text.

The nested div in the second div (with id=“second”) is the last sibling of the second group of p elements, but since it is not a p element, it does not get a green background.

If I use the same HTML but use the following CSS:

p:last-of-type {
  background: green;

both the c and the 3 get a green background.
