Frontend-design Skill

Sorcha uses MudBlazor 8.15.0 for Material Design components with CSS Isolation as the primary styling approach. The design system follows Material Design 3 with custom extensions for blockchain/workflow visualization.

Quick Start

Styling a New Component

@* MyComponent.razor *@
<MudPaper Elevation="1" Class="pa-4 mb-3">
    <MudText Typo="Typo.h6" Class="mb-2">Component Title</MudText>
    <MudText Typo="Typo.body2" Color="Color.Secondary">
        Description text
    </MudText>
</MudPaper>

Custom Component with CSS Isolation

@* MyCard.razor *@
<div class="custom-card @(IsSelected ? "selected" : "")">
    <div class="card-header">@Title</div>
    <div class="card-content">@ChildContent</div>
</div>

@code {
    [Parameter] public string Title { get; set; } = "";
    [Parameter] public RenderFragment? ChildContent { get; set; }
    [Parameter] public bool IsSelected { get; set; }
}

/* MyCard.razor.css */
.custom-card {
    background: white;
    border: 2px solid #1976d2;
    border-radius: 10px;
    box-shadow: 0 2px 8px rgba(0,0,0,0.12);
    transition: all 0.2s ease;
}

.custom-card:hover {
    box-shadow: 0 4px 12px rgba(0,0,0,0.18);
    transform: translateY(-2px);
}

.custom-card.selected {
    border-color: #0d47a1;
    border-width: 3px;
}
