Is it possible to have a loading gif play while my HTML5 is loading in the browser?

I am using an unsupported aspect of UE4 with close to no info online about it other than some old video’s on YouTube. I don’t know html very well and would be willing to pay for help if my vision becomes a reality. I want some sort of animated gif to play wile my scene is loading in the browser. It has some text that displays but I want something more visual to people visiting the site realize its working. I have gotten a loading gif to display and play wile my “game” is loading but when it loads its doesn’t disappear and you cant interact with the “game”. I wasn’t sure where to even post this question.
