Responsive Images
An image can be set to automatically resize itself to fit the size of its container.
If you want the image to scale down if it has to, but never scale up to be larger than its original size, use the w3-image class.
Example
<img src="img_lights.jpg"
alt="Lights" class="w3-image">
If you want the image to scale both up and down on responsiveness, set the CSS width property to 100%:
Example
<img src="img_lights.jpg"
alt="Lights" style="width:100%">
If you want to restrict a responsive image to a maximum size, use the max-width property:
Example
<img src="img_lights.jpg"
alt="Lights" style="width:100%;max-width:400px">
Opacity
The w3-opacity classes make images transparent:
Normal
w3-opacity-min
w3-opacity
w3-opacity-max
Example
<img src="img_forest.jpg" alt="Forest" class="w3-opacity-min">
<img src="img_forest.jpg" alt="Forest" class="w3-opacity">
<img src="img_forest.jpg" alt="Forest" class="w3-opacity-max">
Grayscale
The w3-grayscale classes add a grayscale effect to an image:
Normal
w3-grayscale-min
w3-grayscale
w3-grayscale-max
Example
<img src="image.jpg" alt="Table" class="w3-grayscale-min">
<img src="image.jpg" alt="Table" class="w3-grayscale">
<img src="image.jpg" alt="Table" class="w3-grayscale-max">
Note: The w3-grayscale classes are not supported in IE 11 and earlier versions.
Sepia
The w3-sepia classes add a sepia effect to an image:
Normal
w3-sepia-min
w3-sepia
w3-sepia-max
Example
<img src="image.jpg" alt="Table" class="w3-sepia-min">
<img src="image.jpg" alt="Table" class="w3-sepia">
<img src="image.jpg" alt="Table" class="w3-sepia-max">
Note: The w3-sepia classes are not supported in IE 11 and earlier versions.
Hover Effects
You can also add special effects on hover/mouse-over.
w3-hover-opacity
w3-hover-grayscale
w3-hover-sepia
Example
<img src="image.jpg" alt="Einstein" class="w3-hover-opacity">
<img src="image.jpg" alt="Einstein" class="w3-hover-grayscale">
<img src="image.jpg" alt="Einstein" class="w3-hover-sepia">
Opacity Off
Add transparency on hover:
Remove transparency on hover:
The w3-hover-opacity class adds transparency to the image on mouse-over, and the w3-hover-opacity-off class removes transparency on mouse-over.
Example
<img src="snowtops.jpg" class="w3-hover-opacity" alt="Alps">
<img src="snowtops.jpg" class="w3-opacity w3-hover-opacity-off" alt="Alps">
Constructing a Photo Album
