5 blue Dots Loading Animation

This is a standard 5 dots horizontal loader with pulse animation.

You can add or remove the number of loading dots by adding or removing the HTML code <div class="dot-loader"></div>. You can also change the color of the loader by replacing all the background-color from #b3d4fc with the color of your choice.
