How to create and use HTML anchor tags for linking within the same page in Go?

In Go, you can use the "html/template" package to create and use HTML anchor tags for linking within the same page. Here's an example:

Import the necessary packages:

import (
    "html/template"
    "net/http"
)

Define a struct to hold the data for your HTML template:

type Page struct {
    Title  string
    Anchor string
}

Create a handler function to render the HTML template:

func handler(w http.ResponseWriter, r *http.Request) {
    data := Page{
        Title:  "My Page",
        Anchor: "#section1",
    }

    tmpl, err := template.New("index").ParseFiles("index.html")
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }

    err = tmpl.Execute(w, data)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
}

Create an HTML file (index.html) containing the anchor tag:

<html>
<head>
    <title>{{ .Title }}</title>
</head>
<body>
    <h1>My Page</h1>
    <a href="{{ .Anchor }}">Go to Section 1</a>

    <!-- Rest of your HTML content -->

    <h2 id="section1">Section 1</h2>
    <!-- Section 1 content -->

</body>
</html>

Initialize your HTTP server and register the handler function:

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

Now, when you run your Go program and visit http://localhost:8080, you will see a link titled "Go to Section 1". When clicked, it will scroll down to the target section with the ID section1.
