Blazor UI: Basic Theme

The Basic Theme is a theme implementation for the Blazor UI. It is a minimalist theme that doesn't add any styling on top of the plain Bootstrap. You can take the Basic Theme as the base theme and build your own theme or styling on top of it. See the Customization section.

If you are looking for a professional, enterprise ready theme, you can check the Lepton Theme, which is a part of the ABP Commercial.

See the Theming document to learn about themes.

Installation

This theme is already installed when you create a new solution using the startup templates. If you need to manually install it, follow the steps below:

• Install the Volo.Abp.AspNetCore.Components.WebAssembly.BasicTheme NuGet package to your web project.
• Add AbpAspNetCoreComponentsWebAssemblyBasicThemeModule into the [DependsOn(...)] attribute for your module class in the your Blazor UI project.
• Use Volo.Abp.AspNetCore.Components.WebAssembly.BasicTheme.Themes.Basic.App as the root component of your application in the ConfigureServices method of your module:

var builder = context.Services.GetSingletonInstance<WebAssemblyHostBuilder>();
builder.RootComponents.Add<App>("#ApplicationContainer");

#ApplicationContainer is a selector (like <div id="ApplicationContainer">Loading...</div>) in the index.html.

The Layout

Application Layout implements the following parts, in addition to the common parts mentioned above;

• Branding Area
• Main Menu
• Main Toolbar with Language Selection & User Menu
• Page Alerts

Customization

You have two options two customize this theme:

Overriding Styles / Components

In this approach, you continue to use the theme as NuGet and NPM packages and customize the parts you need to. There are several ways to customize it;

Override the Styles

You can simply override the styles in the Global Styles file of your application.

Override the Components

See the Customization / Overriding Components to learn how you can replace components, customize and extend the user interface.

Copy & Customize

You can run the following ABP CLI command in Blazor WebAssembly project directory to copy the source code to your solution:

abp add-package Volo.Abp.AspNetCore.Components.WebAssembly.BasicTheme --with-source-code --add-to-solution-file

Then, navigate to downloaded Volo.Abp.AspNetCore.Components.WebAssembly.BasicTheme project directory and run:

abp add-package Volo.Abp.AspNetCore.Components.Web.BasicTheme --with-source-code --add-to-solution-file

Or, you can download the source code of the Basic Theme, manually copy the project content into your solution, re-arrange the package/module dependencies (see the Installation section above to understand how it was installed to the project) and freely customize the theme based on your application requirements.
