How Can I Center Text Over an Image Using Flexbox?

Center Text over an Image with Flexbox

Introduction

Centering text over an image is a common layout technique used to create visually appealing and engaging web pages. While centering text has traditionally been achieved using inline styles or absolute positioning, flexbox provides a more modern and flexible approach to this task.

Using Flexbox to Center Text Over an Image

Flexbox is a powerful layout system that allows developers to create complex layouts using only CSS. To center text over an image using flexbox, you can follow these steps:

1. Create a flex container around the image and text.
2. Set the flex direction to "column" to stack the items vertically.
3. Center the text vertically by setting the align-items property to "center".
4. Center the text horizontally by setting the justify-content property to "center".
5. Position the text absolutely within the image container using position: absolute.
6. Use the left and top properties to align the text's center with the image's center.
7. Adjust the translate transform property to center the text accurately within the image.

Example Code

.flex-container {
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
}

.image {
  max-width: 100%;
  height: auto;
}

.text {
  position: absolute;
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
  color: white;
  font-weight: bold;
  text-align: center;
}

<div class="flex-container">
  <img class="image lazy" src="/static/imghwm/default1.png" data-src="image.jpg" alt="Image">
  <div class="text">Center Text</div>
</div>

This code snippet creates a flex container that stacks the image and text vertically. The text is then centered within the image using absolute positioning and the translate transform property.

Alternative Method Using CSS Positioning

While using flexbox is a suitable method for centering text over an image, it's important to note that absolute positioning provides an equally effective solution. By setting the image as the nearest positioned ancestor for the text, you can use the left and top properties with the transform property to align the text precisely over the image.

This alternative method may be preferable in situations where you don't need the additional layout flexibility that flexbox provides or if you want to maintain backward compatibility with older browsers that don't fully support flexbox.
