Preloaders (also known as loaders) are simple animations that are used to keep visitors entertained while the page is still loading - this helps to enhance the user experience.

Bootstrap “spinners” can be used to show the loading state in your projects. They’re built only with HTML and CSS, meaning you don’t need any JavaScript to create them. You will, however, need some custom JavaScript to toggle their visibility. Their appearance, alignment, and sizing can be easily customized with our amazing utility classes.

For accessibility purposes, each loader here includes role="status" and a nested Loading....

Default loader

Use a border spinner for a lightweight loading indicator.

Loader colors

The default spinner uses currentColor for its border-color, meaning you can customize the color with text color utilities. You can use any of our text color utilities on the standard spinner.

Why not use border-color utilities? Each border spinner specifies a transparent border for at least one side, so .border-{color} utilities would override that.

Growing spinner

If you don’t fancy a border spinner, switch to the grow spinner. While it doesn’t technically spin, it does repeatedly grow!

              <div class="spinner-grow" role="status">
                <span class="sr-only">Loading...</span>
              </div>

Once again, this spinner is built with currentColor, so you can easily change its appearance with text color utilities. Here it is in blue, along with the supported variants.

              <div class="spinner-grow text-primary" role="status">

              </div>
              <div class="spinner-grow text-secondary" role="status">
                <span class="sr-only">Loading...</span>
              </div>
              <div class="spinner-grow text-success" role="status">
                <span class="sr-only">Loading...</span>
              </div>
              <div class="spinner-grow text-danger" role="status">

                <span class="sr-only">Loading...</span>
              </div>

Alignment

Spinners in Bootstrap are built with rems, currentColor, and display: inline-flex. This means they can easily be resized, recolored, and quickly aligned.

Margin

Use margin utilities like .m-5 for easy spacing.

          <div class="spinner-border m-5" role="status">
            <span class="sr-only">Loading...</span>
          </div>

Placement

Use flexbox utilities, float utilities, or text alignment utilities to place spinners exactly where you need them in any situation.

Flex

              <span class="sr-only">Loading...</span>
            </div>
          </div>

Loader sizing

You can set different sizes of loaders, both default and material ones.

For default spinners add .spinner-border-sm and .spinner-grow-sm to make a smaller spinner that can quickly be used within other components or, use custom CSS or inline styles to change the dimensions as needed.

Usage

Immediately below the opening <body> tag put the following code.

Edit in sandbox 
        
            
        <div id="mdb-preloader" class="flex-center">
          <div id="preloader-markup">
          </div>
        </div>

The script runs until your page is fully loaded.

To change the Preloader go to mdb-addons/preloader.html in the folder of your unzipped MDB package and replace the existing (default) code with the new Preloader.
