Angular Bootstrap Masks

Angular Masks - Bootstrap 4 & Material Design

Note: This documentation is for an older version of Bootstrap (v.4). A newer version is available for Bootstrap 5. We recommend migrating to the latest version of our product - Material Design for Bootstrap 5.
Go to docs v.5

Angular Bootstrap masks alter the visibility of an element by either partially or fully hiding it. Masks are used to make content more visible in the picture.

Usage

Step 1: Create a wrapper containing class .view.

Show code

HTML

        
            
            <div class="view">
                [...]
            </div>

Step 2: Set a path to the image. If you want to make your image responsive, remember to add a class .img-fluid.

Show code

HTML

        
            
            <div class="view">
                <img src="https://mdbootstrap.com/img/Photos/Others/nature-sm.webp" class="img-fluid" alt="">
            </div>

Step 3: Add a class .mask to cover the image with the pattern.

Show code

HTML

        
            
            <div class="view">
                <img src="https://mdbootstrap.com/img/Photos/Others/nature-sm.webp" class="img-fluid" alt="">
                <div class="mask">
                </div>
            </div>

Step 4: Choose a pattern class from the examples above.

Show code

HTML

        
            
            <div class="view">
                <img src="https://mdbootstrap.com/img/Photos/Others/nature-sm.webp" class="img-fluid" alt="">
                <div class="mask pattern-1">
                </div>
            </div>

Step 5: If you want to add some text, you can use a class .flex-center to center it, and .white-text to give your text a stronger contrast and make it more visible.

Show code

HTML

        
            
            <div class="view">
                <img src="https://mdbootstrap.com/img/Photos/Others/nature-sm.webp" class="img-fluid" alt="">
                <div class="mask pattern-1 flex-center">
                    <p class="white-text">.pattern-1</p>
                </div>
            </div>

Overlays

slight overlay

light overlay

strong overlay

Usage

Instruction and markup are the same like for the patterns. It means you add an overlay class (.rgba-black-strong in the example below) to the .mask.
