Instead of building every UI component from scratch, use a component library to get production-quality buttons, tables, dialogs, forms, and charts out of the box.

MudBlazor — Most Popular

// Install: dotnet add package MudBlazor

// Program.cs:
builder.Services.AddMudServices();

// Usage:
<MudButton Variant="Variant.Filled" Color="Color.Primary"
           OnClick="HandleClick">Save</MudButton>

<MudDataGrid Items="products" Sortable="true" Filterable="true">
    <Columns>
        <PropertyColumn Property="p => p.Name" Title="Name" />
        <PropertyColumn Property="p => p.Price" Format="C" />
    </Columns>
</MudDataGrid>
