Complete the code block such that any element that bumps into an h3 element on the left side will move to a new line.h3 {  position: ;}

To ensure that any element that bumps into an h3 element on its left side will move to a new line, you can use CSS properties effectively. Here’s how you can complete the code block:

Completed Code Block

h3 {
  position: relative; /* This allows for positioning context */
  clear: left;       /* This ensures elements after the h3 will not wrap left */
}

Explanation

1. Position Context: By setting position: relative;, you provide a context for positioning any absolutely positioned children or for using it with other properties.

2. Clear Property: The clear: left; property on the h3 element ensures that any following elements will start below it and not to the left of it, thus forcing a new line whenever an element would otherwise "bump" into it on the left side.

With this CSS, all subsequent elements will avoid appearing alongside the h3 on its left, effectively moving to a new line when the left side is affected.
