Materialize CSS | Preloader
  • Last Updated : 30 Jun, 2020

Preloaders are used for providing symbolic messages that tells users about the website status like “Loading” or “Not crashed”. Materialize provides CSS classes to give various types of preloaders. The following are the available classes provided by Materialize CSS.

Linear: It identifies an element as a progress bar class required for “div” element. There are two different types of linear progress bars.

  • Determinate: It provides basic materialize function to progress indicator.
    <div class="progress">
        <div class="determinate" style="width: 70%"></div>
    </div>
    
  • Indeterminate: It provides animation to progress indicator.
    <div class="progress">
        <div class="indeterminate"></div>
    </div>
    

    Circular: In circular, there are 4 colors and 3 sizes. The spinner should be nested in a “div” preloader-wrapper. The default size is medium, but big or small classes can be added to adjust the size accordingly. You can add the classes spinner-red-only, spinner-blue-only, spinner-yellow-only and spinner-green-only , if you want to show one color.

    <div class="preloader-wrapper big active">
        <div class="spinner-layer spinner-blue-only">
            <div class="circle-clipper left">
                <div class="circle"></div>
            </div>
            <div class="gap-patch">
                <div class="circle"></div>
            </div>
            <div class="circle-clipper right">
                <div class="circle"></div>
            </div>
        </div>
    </div>
    
    <div class="preloader-wrapper active">
        <div class="spinner-layer spinner-red-only">
            <div class="circle-clipper left">
                <div class="circle"></div>
            </div>
            <div class="gap-patch">
                <div class="circle"></div>
            </div>
            <div class="circle-clipper right">
                <div class="circle"></div>
            </div>
        </div>
    </div>
    
    <div class="preloader-wrapper small active">
        <div class="spinner-layer spinner-green-only">
            <div class="circle-clipper left">
                <div class="circle"></div>
            </div>
            <div class="gap-patch">
                <div class="circle"></div>
            </div>
            <div class="circle-clipper right">
                <div class="circle"></div>
            </div>
        </div>
    </div>
    

    Circular Flashing Colors: They are same as circular except it uses all four colors provided by materialize during its display.

    <div class="preloader-wrapper big active">
        <div class="spinner-layer spinner-blue">
            <div class="circle-clipper left">
                <div class="circle"></div>
            </div>
            <div class="gap-patch">
                <div class="circle"></div>
            </div>
            <div class="circle-clipper right">
                <div class="circle"></div>
            </div>
        </div>
    
        <div class="spinner-layer spinner-red">
            <div class="circle-clipper left">

            </div>
            <div class="gap-patch">
                <div class="circle"></div>
            </div>
            <div class="circle-clipper right">
                <div class="circle"></div>
            </div>
        </div>
    
        <div class="spinner-layer spinner-green">

            <div class="circle-clipper right">
                <div class="circle"></div>
            </div>
        </div>
    </div>
