Display html widget

I’m trying to insert code to display the widget.
But for some reason the widget is not displayed.
Here is code:

< script src="https://widgets.coingecko.com/coingecko-coin-price-static-headline-widget.js"></ script>
< coingecko-coin-price-static-headline-widget  coin-ids="bitcoin,ethereum" currency="eur" locale="ru"></ coingecko-coin-price-static-headline-widget >

How to solve this problem?

Where are you trying to embed the widget? The answer will depend on what you’re trying to achieve.

For example:

Does that mean you want it to show below the header on every page of your site?

Yes, sir! [or maybe on main.page] =)
