Arrange the child divs on top of the parent div

Question

Arrange the child divs on top of the parent div

<div id="1">
 <div id="2">
 </div>
</div>

It is proving challenging to position div2 above div1 in the vertical dimension. Applying a negative top position does not have the desired effect, as it appears that the top border of the parent div acts as the boundary for its children.

      |-------|
      | div2  |
------|       |
|     |_______|
|          |
|   div1   |
|__________|

It's challenging to pinpoint the problem without seeing the exact code causing the issue. However, by utilizing this CSS snippet, you can replicate your diagram:

#div2 {
    position:relative;
    top:-30px;
    left:100px;
}

You might be aware already, but ensure to include the position:relative. To observe it in action, check out this fiddle.

Let's not forget that the position: relative attribute grants the children inside an element to be positioned relative to that specific element. This effectively establishes a new reference point for placing elements in relation to each other.

To illustrate, if we have a div (oneDiv) with position: relative, and then another div (twoDiv) nested within it with position: absolute, the second div (twoDiv) will be absolutely positioned, but relative to its parent.

.oneDiv {
  position: relative;
  top: 100px;
  background-color: red;
  height: 200px;
  width: 200px;
}

.twoDiv {
  position: absolute;
  right: -50px;
  top: -50px;
  background-color: blue;
  height: 100px;
  width: 100px;
}

<div class="oneDiv">
  <div class="twoDiv">
  </div>
</div>

Therefore, "top" no longer refers to the top of the entire document, but rather the top of the parent element. By employing the example above, you can ensure consistent layout positioning, so moving .oneDiv will also move twoDiv accordingly.
