Which theme is suitable for Blazor?

Dear Everybody!

I'm woring on Blazor Webassembly for a month.

I'd like to use theme for my project so that it looks like so fantastic.

I have find out Syncfusion and Telerik finally, but they are so expensive for me.

Could you please let me know which theme is suitable for my project?

It's so helpful if you let me know.

Thanks.
