Using CSS to style the last element in a set of dynamic content

Question

Using CSS to style the last element in a set of dynamic content

I am currently working on targeting the last element in a dynamically generated content set.

For instance, here is an example of how the generated content appears:

<div class="block">
  <div class="block-inner">
      <div class="box">
        <h1>Title</h1>
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </p>
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </p>
        <a href="#">A link</a>
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </p>
      </div>
  </div>
</div>

In this scenario, I want the final paragraph to have a margin-bottom: 0;

However, the content could also be generated differently like this:

<div class="block">
  <div class="block-inner">
      <div class="box">
        <h1>Title</h1>
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </p>
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </p>
        <a href="#">A link</a>
        <div class="inner-box">
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </p>
        </div>
      </div>
  </div>
</div>

In this case, I would like the final paragraph within the inner-box div to have zero margin.

I attempted using

block-inner:lastchild {margin-bottom:0;}

but it did not work as expected. I am seeking advice on the best way to target this specific element. Thank you!

There is no foolproof method to accomplish this task. Using .box > p:last-child will only target a p element that is a direct child of .box; it will not select anything in your second example because the last child of .box is .inner-box, not a p.

.box p:last-child is unreliable as it will match all p elements that are the last children of their parent containers, including the last child of .inner-box, even if it's not the final p within the entire .box:

<div class="block">
  <div class="block-inner">
      <div class="box">
        <h1>Title</h1>
        <div class="inner-box">
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
        </p>
        </div>
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. [...]
        </p>
        <a href="#">A link</a>
        <p>
          Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. [...]
        </p>
      </div>
  </div>
</div>

You must consider all potential ways the last p element could be nested inside different structures.

However, if you can determine that the last p element will only ever be either a child of .box or a child of the last .inner-box, then you can outline these two possibilities:

.box > p:last-child,
.box > .inner-box:last-child > p:last-child

If you are unsure about the class name of the intermediate element, you might try omitting the qualification for :last-child entirely:

.box > p:last-child,
.box > :last-child > p:last-child

Even so, this approach does not cover scenarios where the last p may not reside inside the final child within .box.

In essence, you need to devise a selector that considers every possible nested structure in which the last p element may appear; there is no simple way to specify "select the last p descendant of this container in a dynamic structure."

Try using p:last-child

This CSS selector targets the last instance of a <p> tag and applies styles specifically to that element.

.box {
  border: solid 1px
}
.box p:last-child {
  margin-bottom: 0;
  color: red;
}

<div class="block">
  <div class="block-inner">
    <div class="box">
      <h1>Title</h1>
      <p>
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

      </p>
      <a href="#">A link</a>
