Now you can start creating overlay effects.

Basic Image Overlay

The most common overlay technique uses relative and absolute positioning.

Example

<div class="relative w-96">

<img 
src="https://picsum.photos/600/400"
class="rounded-lg">

<div class="absolute inset-0 bg-black/50 rounded-lg"></div>

</div>

Explanation:

Class Purpose
relative parent container
absolute overlay positioning
inset-0 cover entire image
bg-black/50 semi transparent overlay

This creates a dark overlay over the image.

Image with Text Overlay

A common design pattern is placing text over images.

Example

<div class="relative w-96">

<img 
src="https://picsum.photos/600/400"
class="rounded-lg">

<div class="absolute inset-0 bg-black/40 rounded-lg"></div>

<div class="absolute inset-0 flex items-center justify-center text-white">

<h2 class="text-2xl font-bold">
Beautiful Nature

</div>

</div>

Result:

  • image background
  • dark overlay
  • centered text

Used in hero banners and portfolio layouts.

Gradient Overlay

Gradients can make overlay designs more attractive.

<div class="relative w-full h-80">

<img
src="https://picsum.photos/1200/600"
class="w-full h-full object-cover">

<div class="absolute inset-0 bg-gradient-to-t from-black/80 to-transparent"></div>
