How to Vertically Center Font Awesome Icons in Bootstrap Input Boxes

When designing web forms, incorporating icons can enhance usability and aesthetics. However, a common challenge developers encounter is vertically centering Font Awesome icons within input boxes. If you've tried using Flexbox properties like justify-content and align-content, but still haven't achieved the desired result, don't worry! This guide will walk you through a simple and effective solution using Bootstrap 4.

Step 3: Adding the Bootstrap Class

The key to vertically centering the icon is to add the align-items-center class to the root div of your form group. This uses Bootstrap's Flexbox capabilities to align items in the center vertically.

Breakdown of the Code

d-flex: Enables Flexbox on the container, allowing for alignment options.

align-items-center: Centers the items vertically within the Flexbox container.

position-relative: Ensures the absolutely positioned icon aligns correctly relative to the container.

pl-5: Adds padding on the left of the input to make space for the icon.

Complete Code Example

Here’s what the final code looks like, ensuring your Font Awesome icon is centered:

Give it a try in your next project, and say goodbye to alignment woes!
