How do you implement sections in layout pages

Sections in layout pages allow you to define specific areas of the layout that can be filled with content from individual pages. This feature provides greater flexibility and control over the layout, enabling you to customize different parts of the page as needed.

Benefits of Using Sections

Customizability: Individual pages can provide their own content for specific sections, allowing for unique layouts.
Modularity: Sections help keep your layout organized and modular, making it easier to manage.
Reusability: You can reuse the same layout for different pages while customizing specific sections.

How to Create and Use Sections

Define Sections in the Layout Page: In your layout page (e.g., _Layout.cshtml), you can define sections using the @RenderSection method.
Implement Sections in Individual Pages: In your individual web pages, you can define content for the sections using the @section directive.

Sample Code for a Layout Page with Sections

Below is an example of a layout page that defines two sections: HeadContent and FooterContent.

        
            <!DOCTYPE html>
            <html>
            <head>
                <title>My Website</title>
                @RenderSection("HeadContent", required: false)
            </head>
            <body>
                <header>
                    <h1>My Website Header</h1>
                </header>
                <main>
                    @RenderBody()
                </main>
                @RenderSection("FooterContent", required: false)
            </body>
            </html>

Using Sections in an Individual Page

To use the sections defined in the layout page, you would include the following in an individual page, such as Index.cshtml:

        
            @{
                Layout = "_Layout.cshtml";
            }
            @section HeadContent {
                <style>
                    body { background-color: lightblue; }
                </style>
            }
            <h2>Welcome to My Website!</h2>
            <p>This is the home page content.</p>
            @section FooterContent {
                <footer>
                    <p>Custom footer content for the home page.</p>
                </footer>
            }
