Help with nth-child(n)

Help with nth-child(n)

I usually figure out any issues and fix them myself but can’t seem to figure out how to get the nth-child(n) to target the second h1:

Is it the h1 that says “This has been modified”? If so, there are at least a couple of different options. One that would work is h1:nth-of-type(2).

Another selector that would work is h1:last-child, but if you add something after the last h1, I don’t think it would work because that h1 will no longer be the last child.

This page https://code.tutsplus.com/tutorials/the-30-css-selectors-you-must-memorize--net-16048 is a good reference for CSS selectors. Hope that helps!

nth-child index count every children in the parent, so… in your example you have to use body h1:nth-child (13) for the second h1. Btw, you can follow the advice of @nacla01 :wink:


#4

Still a little confused because in the tutorial on here he uses:
$(".target:nth-child(2)").addClass(“animated bounce”);
and it targets two different targets to be animated.
And I tried adding the:
$("h1:nth-of-type(2)").html("<p>This has been modified</p>");
and it still did not change the html.


#5

Can you make a codepen or jsfiddle example?


#6

I cleaned up your code.
You need to use triple backticks to post code to the forum.
See this post for details.

Ok, this is what I found.

You should use h1:nth-of-type(2) if you want to target the second <h1> element. To target only that of the <div class="container-fluid">, you’ll want to change it to .container-fluid h1:nth-of-type(2) (or add your own class/id and use that instead).

h1:nth-child(2) will only match an <h1> that is the second child of some parent element. Like

<div class="some-container">
  <p>Hi there!</p>
  <h1>h1:nth-child(2) will see me, because I'm the second child.</h1>
  <h1>Nope, I won't be seen :P </h1> <!-- If you used `h1:nth-of-type(2)` this will be matched instead -->
</div>

I did a lot of digging and then testing on my own because I still could not get the code to work and I figured out it’s a problem with this:

$("h1:nth-of-type(2)").html("<p>This has been modified</p>"); 

When I change it to a paragraph it does not change it to the same CSS properties that my other paragraph elements have. I changed the <p> tags to <em> tags to see if the sentence would at least change and it did so I guess I would have to go about it another way to have it also inherit <p> properties.

By the way, thanks, Kevcomedia. Wasn’t sure how to properly embed the code on here.
