Thirdly- “Create a new selector that targets the last fieldset
accordingly I have tried but not working!!!

Challenge: Learn HTML Forms by Building a Registration Form - Step 43

Link to the challenge:

lots of questions but maybe once you understand this exercise, many of these will be answers.

You are given some sample code:

p:last-of-type { }

And you are told that this selector targets the last element of type p (paragraph).

So click here to see how this works to target only the last ‘child’ of the document that is of type paragraph: W3Schools Tryit Editor

Feel free to try different code on the left side of the screen and then click Run to see the result.

Then this step wants you to target the last fieldset element.
So then, just replace the selector in the sample code from p to fieldset and it will do that.

Imagine every HTML document is a large family. The browser creates a family tree every time it parses an HTML document. And at the top of the tree it places the HTML tag, and underneath it (like children) are the body or main tags, and underneath them are their children which can be whatever elements you nested inside them.

Once this tree is created by the browser, it reads the CSS and can target specific parts of that tree. (that’s why there are CSS selectors, to tell the browser which style applies to which element in the tree).

Hope this helps somewhat.
