I am developing a static website using HTML/CSS. I have 7 pages in my website and each page has the exact same header content. Is there some sort of import/include capability in HTML?

Here is an example of the kind of thing I would be looking for (note I completely made up the syntax):

[Source (header.html)]

```
<html>
    <head><title>Source Page</title></head>
    <body>
        <div id="myheader">Hello, World!</div>
    <body>
</html>   

```

[Page That Imports From Source]

```
<html>
    <head><title>My Title</title></head>
    <body>
        <div import="id:myheader;source:url('header.html');"/>
    <body>
</html>

```

Thank you!
