Masks

Bootstrap masks

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

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 the class .view.



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

      

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



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

      

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



        <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.



        <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 the class .flex-center to center it, and .white-text to give your text a stronger contrast and make it more visible.



        <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>

Usage

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

See the full list of the overlay colors and intensity below



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

Map of dependencies of SCSS files in MDBootstrap:


    Legend:

    '-->' means 'required'

    All free and pro files require files from 'core' catalog

    'none' means 'this component doesn't require anything except core files'

    A file wrapped by `< >` means that this file make the base component prettier but it isn't necessary for the proper working

    All PRO components require 'pro/_variables.scss' file
