Why does the last-of-type selector work, but the first-of-type doesn't seem to?

The SCSS code snippet below is causing me some confusion:

li {
  &.menu-item-type-custom {
    margin-bottom: 10px;

    a {
      //
    }

    &:last-of-type {
      margin-bottom: 40px;
    }

    &:first-of-type {
      margin-top: 40px;
    }
  }
}

In this code, I am attempting to create spacing at the top and bottom of a section by targeting the first and last dynamically placed li elements.

Initially, I successfully added space at the bottom using the last-of-type selector as shown here:

&:last-of-type {
  margin-bottom: 40px;
}

However, when I tried to do the same for the top using the following code:

&:first-of-type {
  margin-top: 40px;
}

I encountered an issue. The style was not applied, the element did not move, and inspect element didn't show any changes. I attempted different solutions such as using &:nth-of-type(1) without success. To troubleshoot, I tested setting other properties within the &:first-of-type selector, but none worked.

Could this be my error or something else unnoticed? Is there a solution that can resolve this issue?

Thank you.

Understanding that :first-of-type, :last-of-type, and similar pseudo-classes apply to the specific element type they are targeting, such as li, is crucial.

Initially, it may be a little confusing, especially if you adhere to good markup practices where elements are properly segregated. The concept differs from what one might expect with something like :first-of-class (which isn't a valid selector).

Although there are workarounds available, none are foolproof. One particularly well-explained solution can be found in this resource. It offers a clear and insightful explanation.
