I have some code I would like to add to the project. HTML CSS and Java script. The HTML is as follows. The CSS and JavaScript act on the div to simulate water level in a tank. With that said, I will need to add my own css and javascript to the project. Can you give some guidance as to how I might accomplish this?
<--! HTML -->
<div class="tk" data-amount="40">
40%
<div class="lq"></div>
</div>
