W3.CSS provides several classes for styling images, such as rounded corners, circular images, and responsive scaling.
Here are some examples of styled images:
<img src="example.jpg" class="w3-round" alt="Rounded Image">
<img src="example.jpg" class="w3-circle" alt="Circular Image">
<img src="example.jpg" class="w3-responsive" alt="Responsive Image">
You can add a border to images using the w3-border class:
<img src="example.jpg" class="w3-border w3-border-blue" alt="Bordered Image">
