To use CSS blend modes, you can apply the `mix-blend-mode` property on an element. Here's a simple example:

<div style="position: relative;"> <img src="image1.jpg" style="width: 100%; height: auto;"> <div style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; background-color: rgba(255, 0, 0, 0.5); mix-blend-mode: multiply;"></div> </div>
