How to Align Child Divs Side-by-Side within Non-Nested Parent Divs

You have two divs side by side, each within their own parent div. These parent divs are repeated multiple times. You desire to position each pair of child_div_1 and child_div_2 horizontally next to each other.

To achieve this, use the display:inline-block; style property on the child divs. This property allows the divs to align as inline elements without interrupting the normal flow of content. While the divs will display alongside each other, they will retain their status as block elements.

This method provides a simpler way to achieve the desired layout compared to using floats. Here's an example of the modified HTML and CSS:

.child_div_1, .child_div_2 {
  display:inline-block;
}
