Hi There @fxground
Thanks for writing in! Custom development is outside the scope of our support, however I can provide some guidelines to follow.
1.You can add a Text element and then add the following HTML.
<span class="my-caption">LIVE</span> STREAM
Then you can add the following CSS rules into your page’s custom CSS area.
.my-caption{
background-color:red;
color:#fff;
}

2.For the animations, you need to check one of the following resources below and implement accordingly.
