Snackbars inform users of a process that an app has performed or will perform. They appear temporarily, towards the bottom of the screen.
To use the Snackbar, you need to copy & paste the below code

 <div class="snackbar flex-row">
<p class="para-s">Can't send picture. Retry in 5 seconds.</p>
<button class="snackbar-btn">RETRY</button>
<button class="snackbar-btn snackbar-dismiss-btn">X</button>
</div>
