What's Going Wrong?

The user is trying to use vertical-align: middle;, but this property does not apply in the way they expect. The vertical-align property only works with inline or table-cell elements, which means it won't center a block-level element like <h3> vertically within a <div>.

Let's dive into a better solution!

The Solution: Use Flexbox

Flexbox is a powerful layout module in CSS that makes it straightforward to align elements both horizontally and vertically. Here’s how to do it:

Step 1: Set up the Flexbox Container

You’ll need to apply Flexbox properties to the parent <div>. This allows it to align its child elements in a flexible manner.

Explanation of the Properties

display: flex; - This turns the <div> into a flex container.

justify-content: center; - This property centers the flex items (the child elements) horizontally within the div.

align-items: center; - This property centers the flex items vertically. This is what we need to achieve the desired effect!

Final Output

Your final code will look like this:
